Railway Emergency Supplies Management System Research, The Layout Model Of The Emergency Supplies

Emergency supplies is the material guarantee of emergency response, also the material basis for the operation of the emergency system, management of emergency supplies directly determines the effectiveness of emergency response, so it must build a management system which is maturity and scientific for emergency supplies. There is need for modeling and analysis as emergency material storage site allocation and emergency supplies configuration management is key issues and emergency decision-making module in materials management systems. Therefore, this paper combine with emergency supplies management practices, studied the allocation and configuration, two aspects of building emergency material management system, building emergency supplies management information system and Emergency supplies layout problems, in order to achieve a scientific storage site layout, reasonable storage structure and sufficient reserves, full use of limited human, material and financial resources to improve the efficiency of emergency management.This paper began study base on three theories, emergency management, emergency supplies management and emergency supplies layout, to construct the main line building emergency supplies management system, and the sub-line building emergency material management information system and railway emergency supplies layout model.To assist decision-making of railway emergency material management and improve the efficiency of railway emergency material management system, this paper constructs railway emergency material management system, which is to resolve emergency material management at wartime and peacetime. This paper integrates the whole system of organization, process, resource, information and other factors of emergency material management in a scientific and standardized way in order to manage emergency material dynamic with overall process and comprehensive dynamic.We set up hardware and software structure and function structure of emergency material management information system which is the part of emergency material management system, and specified status of MIS, emergency supplies, in the emergency management system, and the relationships of emergency material management information system and emergency material management systems and emergency management system.To achieve emergency supplies management optimization and decision-making optimization module function in the emergency supplies management system, in view of the existing emergency supplies reserve system and location of railway emergency supplies reserve point and the characteristics of configuration, the paper studies railway emergency supplies layout in two aspects, emergency material storage site allocation and configuration through modeling. At first, the paper establishes storage point location model based on the theory, emergency supplies point covering line, and applies to the improved branching pruning search method for solving. Then relaxing constraints for model optimization: under the condition of specified storage points, for the railway emergency supplies storage site allocation problems and the maximum three-arc-sect covering problems based on quantitative restrictions situation, we separately establish comprehensive AHP method, the goal programming method of allocation model and the biggest three-arc-sect cover allocation model. Secondly, the paper proposes emergency storage material classification based on clustering analysis, and we supply different storage way aiming at these different categories, through combining the fuzzy evidence reasoning and case fuzzy reasoning method, we analyse various emergency supplies needs, and then made sure each kind of emergency supplies reserves based on the stock material theory, in order to lower storage cost and inventory cost under the situation of guaranteeing emergency supplies needs.
