Study On Integrated Optimization And Safety Monitoring Information System Of Railway Dangerous Goods Stations

To perform railway dangerous goods transport successfully, special car, stations, sidings(enterprise railway), safety facilities and devices, unblocked transportation corridors, stable amount of goods, efficient transportation organization, perfect information management systems are needed. As one of the railway dangerous goods transportation basic infrastructure, the location selection, construction scale and functional division reasonability of railway dangerous goods stations and sidings are important to improve the railway dangerous goods transport efficiency, satisfy transportation requirements and control environmental risk.So the railway dangerous goods stations and sidings integration and location optimization play a important role not only in the railway dangerous goods transport efficiency but in environmental risk control, this is a urgent issue which is worthy of studying. Among the whole railway goods transport accidents, railway dangerous goods transport accidents account for quite proportion, it affects on economic loss and social influence greatly. So it is important to strengthen railway dangerous goods transportation safety management, however, the research on railway dangerous goods transportation safety management literature limits strategies, lacks technology and system research. Railway dangerous goods transport information construction is just unfolding, but there are no ripe study on theoretical gudance and successful construction project, therefore, further studies are needed. The research of thesis included the following several respect mainly:(1) Based on the practical situation in railway dangerous goods transport, thesis firstly limits its attention to the influence of railway dangerous goods stations and sidings upon the economic scale and scope of railway dangerous goods transportation as well as the potential enviromental risks, on the basis of which suggestions for reasonable allocation of railway dangerous goods transportation resource and integration of stations and sidings are put forth. Then, thesis summaries and compares the railway dangerous goods transportation relative researches direction and progress in-china and abroad, points out railway dangerous goods transportation productivity distribution, location optimization, and relative theoretical system construction, modern maths method researches are lack, and makes an overview of location problems research and railway dangerous goods transport information construction situation.(2) The railway dangerous goods transport system components and the relationship of them are analyzed. Using the research method of system dynamics, the relationship among railway dangerous goods transportation system and its main external factors is analyzed, and the causality-feedback-loops are studied, such as railway dangerous goods transportation and social economy, other modes of transportation, science and technology, environment, security causality, supply&demand cost causality-feedback-loops. On the base of the analysis, some countermeasures and suggestion of developing railway dangerous goods transportation are proposed pertinently.(3) In order to analyze the present railway dangerous goods stations and sidings distribution, from the supply and demand adaptability view, thesis constructs the evaluation model of the radiation power of railway dangerous goods stations and sidings, and the fuzzy C-means algorithm is used in the service level clustering of regional railway dangerous goods transport productivity distribution based on GIS, the railway dangerous goods transport productivity distribution situation in sichuan as example is analyzed. Proposed the study of the railway dangerous goods stations functional division, based on CAS theory, railway dangerous goods stations complex adaptive system model with require and service pattern is established, by using the computer simulation method, studies the process of railway dangerous goods stations functional division and hierarchy system.(4) Railway dangerous goods stations and sidings hazard assessment system is studied, applying the set pair analysis theory to the hazard assessment in the given field, the new approach here recommended is not only suitable for the risk assessment, but also provides the gist to find the potential hazards that are likely to lead to dangerous accidents so as for the managers and departments concerned to take measures beforehand, and carry on safety management by setting up a relevant standard for the corresponding departments facing similar problems. Introducing the quantitative regional environmental risk theory into railway dangerous goods stations and sidings, based on the inherent environmental risk calculation of railway dangerous goods station and sidings, through the model of physical field, the regional environmental risk field model of railway dangerous goods station and sidings is established, the application effectiveness of the method is demonstrated.(5) The multi-criteria integrated railway dangerous goods stations and sidings multi-objective location-allocation optimization method is proposed, the method firstly comprehensively considers present railway dangerous goods stations and sidings conditions, makes multi-criteria decision evaluation to reject railway dangerous goods stations and sidings which need to be optimized allocation, the dangerous goods carried by these stations and sidings need to transfer the remaining stations and sidings, then, makes transportation demand investigation, based on the comprehensive utility evaluation of transportation demanders'selection about stations and sidings and the quantitative stations and sidings regional environmental risk evaluation, railway dangerous goods stations and sidings multi-objective location-allocation integrated optimization model is builded, and the combined Genetic Algorithms and bi-level Simulated Annealing are designed to solve model.(6) Railway dangerous goods transport system is a control system, the control theory which is the guiding theory of railway dangerous goods transport safety monitor information construction is studied, thesis analysis the necessity and feasibility of railway dangerous goods transport system safety monitoring information, studies the present developing, building and working railway dangerous goods stations and sidings safety monitor information system construction scheme.Finally, thesis summarizes the research work and results of the full paper, and puts forward several innovative points and jobs proposed needing to further investigate in the some futures of the thesis.
