   1. A Route-Planning Algorithm Based on Subway Passenger Routes Choice Behavior Analysis
    作者姓名: Yongsheng Zhang, Enjian Yao, and Yang Yang  
  摘要:   With the rapid development of city subway system, subway networks get more and more complex in some China cities and subway route planning service becomes necessary. Usually, conventional route planning algorithms are based on the least travel time rule. However, it shows that the route with least travel time is only chosen by 68% passengers based on a subway passenger’s travel behavior survey in Beijing in 2012. It illustrates that travel time is not the only factor influencing passenger’s route choice behavior. So it is necessary to establish a new route planning algorithm based on the generalized cost which considering multiple influencing factors to reflect the real route choice preference. First, using the questionnaire surveyed data collected in Beijing Subway, a passenger route choice model is established to analyze the subway passenger route choice behavior based on the discrete choice theory. In which, the factors such as travel time, transfer time, number of transfers and congestion degree in the car of train are included in utility function, but ticket price is excluded because of the uniform fare ticket system in Beijing Subway. Second, the route planning algorithm is proposed. In which, the most suitable route for subway passengers is found by Dijkstra Algorithm with the greatest utility value, and together with another two routes with the least travel time and the least number of transfers respectively are provided to passengers. Finally, the proposed new route planning algorithm is compared with the conventional one. The results show that the greatest utility value route is more consistent with the real situation.

    作者姓名: Li Li, Baocen Yang, Guannan Zhou, and Shuo Xu  
  摘要:   Among the various modes of transportation, inland water transportation is a mode that has special advantages of large capacity, high productivity and low fuel consumption. So the inland water transportation has stronger competition ability as well as a tremendous potential in further development. In China, Chang Jiang has already become the world’s busiest river with the lead of world’s cargo volume for 7 years. To meet the rapidly increasing need of inland waterway transportation of Chang Jiang, besides the regular waterway maintenance, the new technology should be adopted to make the full use of the established navigation environment, among which the inland ENC is the most used and developed through the worldwide. Due to China’s special navigation environment, the inland navigation in China has some fundamental distinctions from U.S and European navigation. Furthermore, with different navigation aids and other objects, a valid quality control method of those source data hasn’t been determined yet. So China has come up with its own standard – the CJ-series. However, the standard is newly developed and, for the first time, used in Chang Jiang. In order to conduct the standard more efficiently, this paper analyzes the producing procedure of Chang Jiang inland ENC source data, starts from the quality inspection of pre-processed data, source data production method and its quality check method, and finally investigates a set of effective Chang Jiang inland ENC source data quality control method, which is already proved to be useful and productive in the source data production of Chang Jiang inland ENC.

In China, Chang Jiang has already become the world’s busiest river with the lead of world’s cargo volume for 7 years. To meet the rapidly increasing need of inland waterway transportation of Chang Jiang, besides the regular waterway maintenance, the new technology should be adopted to make the full use of the established navigation environment, among which the inland ENC is the most used and developed through the worldwide. Due to China’s special navigation environment, the inland navigation in China has some fundamental distinctions from U.S and European navigation. Furthermore, with different navigation aids and other objects, a valid quality control method of those source data hasn’t been determined yet. So China has come up with its own standard – the CJ-series. However, the standard is newly developed and, for the first time, used in Chang Jiang. In order to conduct the standard more efficiently, this paper analyzes the producing procedure of Chang Jiang inland ENC source data, starts from the quality inspection of pre-processed data, source data production method and its quality check method, and finally investigates a set of effective Chang Jiang inland ENC source data quality control method, which is already proved to be useful and productive in the source data production of Chang Jiang inland ENC.

   33. Study on 3-D stereo of Marine Features on UAV High Resolution Remote Sensing Images
    作者姓名: Jing Bai, Jun Sun, Bolin Zhu, Weiwei Ma, Guixiang Zheng, and Fang Wu  
  摘要:   Unmanned Aerial Vehicle remote sensing (UAV-RS) has been applied in many fields, due to its advantages of high time and high-resolution. But recent research is mainly focused on two-dimensional applications such as image registration, mosaic, classification and so on. What’s more, most of such applications are confined to the land application. Creatively, this study focuses on three-dimensional applications based on UAV high resolution remote sensing images for marine management. Firstly, SIFT(Scale-invariant feature transform) algorithm is employed to detect correspondence points between every two adjacent UAV images automatically, which will help match the same maritime feature on different images. Secondly, multi-view geometry is used to rebuild the three-dimensional reconstruction of three-dimensional scene for specific features on the image by obtaining the three-dimensional position and orientation of the camera while photographing. Thirdly, the theory of binocular stereo vision is used for 3-D stereo processing of images. Finally, the two images are synthesized for enhanced display with three-dimensional display devices. Developed in VC program environment, this study builds its prototype system, which achieves a nice three-dimensional visualization under any of the three modes including Anaglyphic 3D, Polarization 3D and Active Shutter 3D. The result shows that 3-D stereo processing brings structured details of maritime feature such as ships, cruises, sailing assistance and security facilities and so o, which provides a new way for feature interpretation on UAV-RS images and provides a new idea for marine management.

    作者姓名: Tao Guo, Huaihan Liu, and Xiumin Chu  
  摘要:   Chan Jiang is the largest inland water system in China. The length of the trunk is 6300 kilometers, the longest in China and third longest in the world. The section above Yibin is considerably small and the shipping at present is underdeveloped. Below Yibin, the river is wide and deep, this section of Chang Jiang makes itself an important transport line and the shipping there is flourishing. However, due to its special geographical condition, the water level of the trunk varies from section to section and time to time, which, to some extent, will affects the environment of navigation. To guarantee the smooth passage for sailing vessels and make the full use of the navigable trunk, the paper introduces a short- and mid -term water level forecasting method. With the analysis of the water level and flow records of the past decade, the paper determines the flow and water level models of the key water level station to forecast the water level based on the flow information. Then, with the method of corresponding water level,establishes the corresponding water level relation along the Chang Jiang river and provides a real-time hydrological information for Chang Jiang waterway management.

    作者姓名: Zhenyi Chen, Xiumin Chu, Zhe Mao, Yichen Li, and Tong Liu  
  摘要:   It is the foundation of intelligent inland waterway management to collect the location information of aids to navigation (AtoN) with high precision. Differential Global Positioning System (DGPS) is an effective approach to improve the accuracy of the Global Positioning System (GPS). This paper gives an accurate positioning method for AtoN through applied the DGPS and ZigBee. In this system, via ZigBee in ZigBee network, AtoN transmits its own GPS data to the GPRS AtoN which has a GPRS module. The GPS reference station receives and decodes the local DGPS data. Then, the GPS data of AtoN and the local DGPS data are broadcasted to the supervision center of AtoN management through GPRS. The accurate position of AtoN is computed in supervision center. This system will improve the positioning accuracy of AtoN in nearby area of reference station. It can be used for alarm of AtoN drift and improve the navigation safety of inland vessels.

    作者姓名: Zhenyi Chen, Xiumin Chu, Zhe Mao, Yichen Li, and Tong Liu  
  摘要:   It is the foundation of intelligent inland waterway management to collect the location information of aids to navigation (AtoN) with high precision. Differential Global Positioning System (DGPS) is an effective approach to improve the accuracy of the Global Positioning System (GPS). This paper gives an accurate positioning method for AtoN through applied the DGPS and ZigBee. In this system, via ZigBee in ZigBee network, AtoN transmits its own GPS data to the GPRS AtoN which has a GPRS module. The GPS reference station receives and decodes the local DGPS data. Then, the GPS data of AtoN and the local DGPS data are broadcasted to the supervision center of AtoN management through GPRS. The accurate position of AtoN is computed in supervision center. This system will improve the positioning accuracy of AtoN in nearby area of reference station. It can be used for alarm of AtoN drift and improve the navigation safety of inland vessels.

  摘要:   Typhoon is one of the most serious disastrous weather that threatens the safety of ship’s navigation. The ocean going ship typhoon avoidance system under the shore-based information support was designed and achieved. The system includes three subsystems and five databases. Based on electronic chart platform, through ship-shore communication subsystem automatically, the system obtains shore-based meteorological information (especially typhoon intensity and motion path information). Combined with ship data information (ship limited wind wave resistance ability and cargo carrying condition), the system gives a risk assessment on the original route, uses the goal circle method and radar plotting principle to calculate the starting time that ship takes typhoon avoidance action and the measures to avoid typhoon. The application results indicate that the system can reduce the influence of typhoon on the ship operation, improve the safety and economy of ships.

   93. Navigation Marks Collision Detection Based on Millimeter Wave Radar and Accelerometer
    作者姓名: Qizhi Yin, Gang Huang, Zhe Mao, Chen Zhou, and Jianglong Wan  
  摘要:   The navigation mark is collided by the sailing ships frequently during working. It is important to establish the navigation mark collision detection system for reducing the collision between the navigation mark and the sailing ships and finding out the ship that causes trouble. According to the features of the navigation mark and the current detection technique, a kind of navigation marks collision detection system is established. In the collision alarm part, the distance, which is between the navigation mark and the ship nearby, is measured by millimeter wave radar. When the distance is less than the critical value which is set in advance, the alarm information will be transmitted to the administration of navigation affairs through AIS, and the image information of the ship will be recorded by the camera on the navigation mark. In the collision detection part, the accelerometer is used to judge whether there is a collision happened through detecting the acceleration of the navigation mark.

    作者姓名: Ping Deng, Shiqing Lu, and Hanbin Xiao  
  摘要:   This study aims to evaluate the influence of port factors (port logistics demand, port logistics supply, and port logistics effect) on the capabilities of port logistics. Econometric aspects of SEM over port logistics industry are sought because recently the measurement of unobservable variables has gained increasing attention in port logistics capability, and the SEM could employ multi-index to reflect unobservable variables (latent variables) and provide a method for processing measurement error. SEM can more accurately than other mathematical methods estimate the relationship between the factors of the entire model. The construction of hypothesized model proves to fit the port logistics very well. The findings reveal the restrictive factors of the impact on port logistics development, and provide port administrators with scientific and policy guidance. In addition, this paper presents a tutorial on the application of SEM, and offers port logistics researchers a better understanding of the application of this useful statistical modeling technique.

Using training sampling and K-multiple principal component analysis to optimize parameters of the kernel function, it obtained a model of condition assessment compatible with SVM. Simulation using MATLAB shows that it can provide high precision and is suitable for generalization as well as improving ship safety.

  摘要:   China's Yangtze River has become the largest volume of the navigable rivers in the world, however, there are some problems of its development compared with the inland water transportation of the developed countries, especially the imbalance between shipping supply and demand of Yangtze River. This paper focuses on the demand from two perspectives of the time series and the influencing factors, it forecasts the demand with Regression Analysis, Output Value of Coefficient Method, Elastic Coefficient Method, Time Series Analysis and the weighted combination of those methods. And then this paper analyzes the supply with the econometric model, which predicts the capacity and ship trends in order to determine the trend of change in the form of ship operational organization. By comparison and calculation, the results indicate that the imbalance between the supply of Yangtze River and the shipping demand of economic society along the river has become the principal contradiction of the development of the inland water transportation of Yangtze River in China. Finally, this paper proposes that it can solve the problem through optimizing the structure of freight capacity.

    作者姓名: Shengli Li, Zhengwei He, Jia Shi, Youqin Zheng, Xiaoqiao Geng, and Zhenghao Wu  
  摘要:   Mooring lines tension determination is of significant importance for mooring design and berthing structures. Tension determination model is the base for mooring lines force analysis and morphological simulation. After analyzing the mooring force of a ship mooring system, a mooring lines tension determination model is proposed, based on spring-micro-element model, for calculating the mooring lines force which a ship mooring system subject to wind, waves, and currents. Then, a morphological simulation model is put forward to simulate the spatial form of mooring lines, by the approach of function force balance under three-dimensional coordinate system. Next, a fast solution method of the model is found for optimizing the solution of morphological simulation model. This research can provide methodological and technological support for describe the shape, position and posture of mooring lines in navigation simulator, and can also provide exploration on ship mooring system research.

   145. Research on the Lateral Load Capacity of Offshore Platform Piles under Scour Conditions
    作者姓名: Fen Li, Dan Hu, and Renjun Yan  
  摘要:   To the offshore and coastal structures that founded on piles, scour has coming to be one of the most significant factors to be considered in the design. This paper is aimed at investigating the effect of scour on the lateral response of piles embedded in clay. Factors such as the scour depth (S), the pile slenderness ratios (L/D), and the pile head configurations were studied to show their effect on the variation of lateral load capacity (PVC). The results show that for the piles with smaller ratio value of scour depth to pile diameter (i.e. S/D <1), scour has smaller influence on the lateral load capacity, and for the piles with smaller pile slenderness ratio (i.e. L/D <10), the lateral load capacity will largely influenced by the scour. Meanwhile, the free-head pile is more sensitive to the PVC induced by scour than that with a fixed-head.

    作者姓名: Huaqin Zhang, Weiguo Wu, Zhonghua Tan, and ZhiYou Cheng  
  摘要:   Collision between ship and bridge or anti-collision device of bridge is a complicated nonlinear dynamic response process with water influence in a short time which will result in disaster. And to study its mechanism becomes essential and complicated. A collision experiment that a wood ship model collides with a fixed pressure sensor was carried out with water or without water in this paper. The peak values of impact forces of these collisions are compared, and the influence of water on collision is studied. Based on a large number of experiment data fitting analysis, it is shown that the peak values of impact forces of model with water are smaller than that without water in the same draft, and the decreased range is from 2 percent to 8 percent. It is proved that collision motion is impeded by the damping effect of water, and then the peak values of impact forces decreased. It is concluded that when added mass coefficient is used for studying collision problems between ship and bridge or anti-collision device of bridge, the coefficient value should be negative with the damping influence of water.

  摘要:   In the mechanical seal of the marine stern shaft, the structure of the narrow face seal is usually superior to the wide face seal. However, it will also lead to larger deformation and higher temperature on the seal face. Based on the narrow face seal, the structure of seal face will be designed to be dam seal, and we optimize it to improve its sealing performance in the aspect of temperature, stress, deformation etc. Build its finite element model using the integral-contact method. Study it by thermal-structural coupling. The results show that the dam seal structure can reduce the maximum temperature and the maximum stress of the seal face of narrow face sealing. It also will reduce the deformation and the seal gap of seal face.

  摘要:   As the fast development of marine transportation in China and the increasing amount of worldwide coal trading, the proportion of coal carrier in ocean transportation increased every year in China. At the same time, the frequency of accidents is increasing every yea. Furthermore, because of the special properties of coal, the safety of coal during marine transportation as bulk cargo attracts extensive attention. In order to avoid accident during a voyage, both International Maritime Organization and some countries have instituted regulars related. In this paper, the mechanism of coal spontaneous combustion was analyzed and main forecast and prevention technology about coal spontaneous combustion were also summarized. According to the recent accidents during coal marine transportation and based on the latest “International Maritime Solid Bulk Cargoes Code”, we provide some useful recommendations to avoid damage and ensure the coal marine shipping safety.

   173. Safety Analysis of Typhoon Anchorage in Haikou Bay and its Countermeasures
    作者姓名: Shanshan Du and Houzhong Chen  
  摘要:   Haikou Bay has a large traffic flow, and it is affected by typhoon significantly, and the typhoon anchorages in Haikou Bay have some glaring problems. Through questionnaire survey and consulting experts, the situation of typhoon anchorages is evaluated by using fuzzy comprehensive evaluation & Analytic hierarchy process (AHP). The results show that the typhoon anchorages have a high risk, and the volume of typhoon anchorages tend to be saturated, and the anchorage berths are strained, and the number of typhoon anchorages cannot adapt to the traffic flow. Some countermeasures are given to ease the risk of typhoon anchorages efficiently, such as optimizing the arrangement of typhoon anchorages, building a new typhoon anchorage, implementing dynamic monitoring, etc.

    作者姓名: Zhengwei He, Dongwen Zhan, Tianhao Wu, and Shaolong Zhou  
  摘要:   Oil film extension model is regards as one of the main methods to calculate the track and fate of continuity of oil spill, which is accurate to calculate the oil spill trajectory, but is still inadequate for the form of the analog reliability of oil film (OF) diffusion range and OF shape. One of the reasons is that the methods only considering the OF leading-edge extension, but ignoring the expansion of oil film’s flanks. Based on the theory of Fay, the Whole Oil Film Elliptic Extension Model (WOLEEM) is established to reflect the whole oil film (WOF) overall expansion. The WOF is divided into four sections of elliptic arc, the length change of major and minor axis of which describe the expansion of OF. Then using three-link model of Fay, obtains the track of film leading-edge extension that can drive the expansion of back film flanks. Finally, basing on the elliptical extension theory of Lehr to make sure the wind would affect the film shape by changing the size of major and minor axis of elliptic arc. The conclusion is WOLEEM realize the extension movement of oil film flanks by creatively relating flanks boundary to leading-edge extension.

   201. A Game-Theoretic Analysis on Dividing the Limited Budget between Building Emergency Facilities and Preparing Resources
    作者姓名: Bing Shi, Wei Yang, and Xianqiao Chen  
  摘要:   Given the limited budget, when making plans, the relevant emergency authority first needs to determine how to divide the budget between building the emergency facilities (including the construction of facilities and the training of emergency team) and preparing emergency resource (including various types of resource). However, because of the limited budget, there exists a conflict between building emergency facilities and preparing emergency resource. Therefore, the authority should have an effective way to split the budget between building facilities and preparing resource in order to maximize the recovery of the loss. In this paper, a game theoretic method is proposed to address this problem. In more detail, this paper proposes a mathematical framework to describe this problem. Then this paper uses evolutionary game theory to address this problem to find the Nash equilibrium solution, and describe how to split the budget effectively.

   202. A Game-Theoretic Analysis on Dividing the Limited Budget between Building Emergency Facilities and Preparing Resources
    作者姓名: Bing Shi, Wei Yang, and Xianqiao Chen  
  摘要:   Given the limited budget, when making plans, the relevant emergency authority first needs to determine how to divide the budget between building the emergency facilities (including the construction of facilities and the training of emergency team) and preparing emergency resource (including various types of resource). However, because of the limited budget, there exists a conflict between building emergency facilities and preparing emergency resource. Therefore, the authority should have an effective way to split the budget between building facilities and preparing resource in order to maximize the recovery of the loss. In this paper, a game theoretic method is proposed to address this problem. In more detail, this paper proposes a mathematical framework to describe this problem. Then this paper uses evolutionary game theory to address this problem to find the Nash equilibrium solution, and describe how to split the budget effectively.

    作者姓名: Die Wang and Dangli Wang  
  摘要:   Nowadays, low-carbon economy develops rapidly. The growing overall carbon emissions of waterway transportation industry attract more and more attentions all over the world. Inland vessel, as an important part in China’s transportation industry, has huge potential in achieving lower level of carbon emissions, which will directly contribute to the reduction of carbon dioxide emissions and the mitigation of greenhouse effect. Consequently, establishing a comprehensive and objective system that can scientifically evaluate the low carbon emissions of Inland vessel is of great significance to implement energy conservation, control the inland ship carbon emissions, and develop green ship, low-carbon economy. Constructing a carbon emission evaluation system for inland vessels systematically and scientifically takes the characteristics of inland vessels and greenhouse gas emission into consideration, what’s more, it bases on maneuverability and comparability principle, uses qualitative and quantitative methods, and combines with detailed illustration of corresponding evaluation criteria and level. In addition, analytic Hierarchy Process(AHP)can determine the weight of all related factors in the carbon emission evaluation system and help to assess the evaluation criteria of inland vessels' carbon emission. Finally, to further develop low carbon, several measures be put forward. The measures,base on the characteristics carbon emissions of inland vessels and inland waterways and factors affecting the carbon emissions of inland vessels, will be demonstrated from operational, technical and market perspectives. It is proved that employing these measures can greatly reduce the carbon emissions of inland vessel, boost operation economic efficiency, and enhance global competitiveness of shipping industry.

    作者姓名: Lingzhi Sang, Zhe Mao, Xinping Yan, and Xiumin Chu  
  摘要:   The vessel track contains straight line segment when the vessel is straight ahead and the curve when the vessel is turning. At this stage, there are two methods to describe the track: (1) simplify the curve to a point and get the track by connecting straight line segments; (2) simplify the curve to an arc and connect the line segments to get the track. A new quantificational description method of vessel track is expounded. It could show the track more accurately and clearly and describe the state of vessel motions more really, which are important for analysis vessel motions and generalizing the voyage methods in a specific area. Based on the maneuvering characteristics of vessel, the track is divided into five parts: two line segments, two cubic curves and an arc, and they are tangent sequentially at the joint points. The tangent points need be found from AIS data firstly, and with the rest data, the center point, the radius and the central angle of the arc can be calculated to describing the arc, and the two cubic curves can be described by cubic spline interpolation, and the whole track can be shown by connecting the five segments. By this method, the vessel track could be described quantitatively as the tangent points, center point, radius and central angle.

  摘要:   Centered on the problems of system failure on civil nuclear-powered ship, the first problem asked to resolve is that suitable and operational method is needed to build system fault model for nuclear-powered ship in order to provide a theoretical basis and technical support for safety analysis of operating nuclear-powered ship. Analyzing the failure of nuclear-powered plant, professionals in the industry usually adopts relatively mature determinism assessment and increasingly mature probability risk assessment (PRA). The vast models of fault tree assessment (FTA) and event tree assessment (ETA) are built under the system of PRA. Having analyzed the functions and relationships of each system of civil marine nuclear power plant, relatively complete fault model of primary system is built for nuclear-powered ship based on three elements, combining some methods of system failure modeling in the system security theory. It is an open model, and the successors can refine and expand it. The modeling contains some thought and logic of FTA, ETA and analytic hierarchy process, but it does not rely on any method, which will be used as the platform of civil nuclear-powered ship analysis in the future.

   229. An Application of Cloud Focus Theory in Assessment for Ship Oil-spill Risk
    作者姓名: Ming Huang and Weidong Gan  
  摘要:   As ship oil-spill has become one of the most important factors incurring ocean pollution, it is important to predict and evaluate the risks of ship oil-spill by scientific methods. The paper identifies risk factors via analyzing historical data and expert experience in terms of man-machine-environment and builds an evaluation model of the risk of ship oil-spill based on cloud focus theory. The application of cloud focus theory quantitatively evaluates the risk of ship oil-spill and confirms the risk level of ship oil-spill. Finally, the model has been applied to NingBo-ZhouShan port waters, resulting that the risk level of ship oil-spill in this waters locates between lower and very low, more inclining to very low. The work has a certain reference value for making a emergency plan of ship oil-spill in some waters.

   237. Consequence analysis of LNG leakage accident based on numerical simulation
    作者姓名: Shanshan Fu, Xinping Yan, Di Zhang, Zhiyong Lu, and Chengpeng Wan  
  摘要:   With respect to global warming, energy consumption has gradually transformed into clean resources. Especially in terms of transportation industry, conventional sources are replaced by liquid natural gas, which is produced by compressing and cooling natural gas to -162 degree Celsius, is growing with the speed of 10% per annum. On account of the different provenance and criterion, chemical property diversity existed in different kinds of LNG. With the continued development of LNG consumption, the safety issues are worth concerning in the LNG transportation process, e.g. the ultra-low temperature may be threatening once leakage happens. Furthermore, LNG leakage may also give rise to the concern of fire and explosion. Therefore, it is significant to study the LNG leakage accident in the transportation process. In various LNG transportation modes, tank container is a flexible transportation method which supports waterway, road and railway as well as multimodal transport. This article chooses the 40 feet tank container as a demonstration and researches its safety problems in transportation process, especially the consequences of LNG leakage from tank container. For the difference property of LNG resources, component influence has been considered. Due to the fact that relevant historical data is rare, a numerical simulation method is used in this paper to simulate the different constituents LNG leakage accident. The research findings would be helpful for the emergency planning and response of LNG accident.

    作者姓名: Jishuang Zhu and Yujun Tian  
  摘要:   Big swings in container shipping have been paid widespread attention in recent years. To provide effective early warning methods, the leading indicator for China's foreign trade container transport are mainly investigated. Firstly, the effects of domestic and international macroeconomic situation on China’s foreign trade container transport are analyzed. The key influence factors and fluctuation characteristic are discussed. Secondly, the four monitoring indexes, including new export orders index of China, China’s electricity generation, America's consumer-confidence index and the inventories/sales ratios of America's merchant wholesalers, are presented. Finally, a composite leading indicator for China's foreign trade container throughput is proposed by the principal component analysis method. The trial operation result demonstrates the validity of the proposed indicator.

    作者姓名: Wenjuan Zhang, Qing Wu, Zhe Mao, and Lingzhi Sang  
  摘要:   Inland waterways are relatively narrow, in which vessel yaw risk is high. Without timely warning and course correction, yaw will lead to grounding or running on the rocks or other accidents. To find an early warning method, a geometric model of vessel yaw risk is established by predicting the possible locations of the vessel after a certain period of time. As vessels yaw under the influence of wind and current, the drift caused by wind and current are taken into consideration when the model is modified. The model is used to quantify vessel yaw risk. According to the value of risk, warning levels are divided and evasive strategies are discussed.

    作者姓名: Di Cui and Hua Zhang  
  摘要:   Structural properties of the ship container logistics network of China (SCLNC) are studied in the light of recent investigations of complex networks. SCLNC is composed of a set of routes and ports located along the sea or river. Network properties including the degree distribution, degree correlations, clustering, shortest path length, centrality and betweenness are studied in different definition of network topology. It is found that geographical constraint plays an important role in the network topology of SCLNC. We also study the traffic flow of SCLNC based on the weighted network representation, and demonstrate the weight distribution can be described by power law or exponential function depending on the assumed definition of network topology. Other features related to SCLNC are also investigated.

  摘要:   Structural properties of the ship container logistics network of China (SCLNC) are studied in the light of recent investigations of complex networks. SCLNC is composed of a set of routes and ports located along the sea or river. Network properties including the degree distribution, degree correlations, clustering, shortest path length, centrality and betweenness are studied in different definition of network topology. It is found that geographical constraint plays an important role in the network topology of SCLNC. We also study the traffic flow of SCLNC based on the weighted network representation, and demonstrate the weight distribution can be described by power law or exponential function depending on the assumed definition of network topology. Other features related to SCLNC are also investigated.

    作者姓名: Haiyan Wang, Hui Jiang, and Liang Yin  
  摘要:   Human factors is becoming the main cause of maritime accidents which occurred frequently in recent years, however the key of preventing accidents is to grasp the cause mechanism of human factors and the weakest link in human factors system. Based on numerous researches on human factors in maritime accidents, the complex system brittleness theory is applied to the cause mechanism research of the human factors. We built up a human factors brittle model which analyzes all kinds of brittle-relationships inside the system and vital human factors. According to the analysis of human factors’ influence on system brittleness in light with simulation results, targeted control strategy is proposed which provides a new method for the research on cause.

   301. Navigation Environment Factors for the Investigation and Evaluation of Water Traffic Safety in the Yangtze River
    作者姓名: Bing Wu, Xinping Yan, Xing Sun, and Guoping Guo  
  摘要:   This work aims to investigate the traffic safety in Yangtze River taking the navigation environment factors into account. Since accident data can directly represent the water traffic safety situation to some extent, it is widely used to evaluate the water traffic safety in Yangtze River. The absolute accident index and relative accident index are two kind of reasonable assessment data, but they can hardly represent the real sense in different waterways when the navigation environment is changed. To overcome this problem, the data envelopment analysis (DEA) is employed for the evaluation of water traffic safety aiming at different navigation environments in this paper. Firstly, a detail accident data during 2009-2011 is described which is officially issued by Maritime Safety Administration (MSA) of China in four different waterways and three water levels, Moreover, the corresponding navigation environments are also analyzed. Then the evaluation of water traffic safety is studied by applying C2R and C2GS2 model. Finally the results of the theoretical models are compared with traditional methods. This method can evaluate the water traffic safety in different waterways. The traffic flow, traffic accident and the level of water traffic safety can be evaluated more scientifically and precisely. In the face of different navigational environment and water-traffic safety situations, the MSA can use these data and/or conclusion to improve their management level.

   305. Study on Waterway Traffic Risk Assessment and Countermeasure of Guangxi Reservoir Area
    作者姓名: Songyin Yan, Huiyuan Jiang, and Chengpeng Wan  
  摘要:   There are three inter-provincial co-administration oversize reservoirs in Guangxi area, which are Tianshengqiao, Longtan and Baise hydro-junction. Also, Guangxi is the foundation of the development of cascade hydropower stations of a national project named power transmission from west to east, where distributes a number of key hydropower complex project reservoir areas. Because of numerous small ships and complex navigation environment, the water safety situation is serious in reservoir area. In this paper, the water traffic safety evaluation index system of this region has been established, by analysis of the status of the water traffic safety of the reservoir and key risk factors identified from four aspects like human, ship, environment and management. What’s more, through risk assessment and analysis of water traffic safety of the reservoir area, the safety level of indicators of the reservoir safety evaluation system has been obtained, and the state of the region's water traffic safety has been determined, by using PSR (pressure - state - response) evaluation theory, combined with the Analytic Hierarchy Process method and linear quadratic evaluation function. On the basis of safety evaluation, ten major risk sources of water traffic safety with characteristics of the reservoir have been identified, such as the crew education level, safety and technical conditions of ships, management of shipbuilding and so on. Finally, regulatory countermeasures of water traffic safety have been put forward, with respect to the characteristics of reservoir and key risk sources.
