Computer-Aided Decision-Making System On Railway Transportation Program For Out-of-Gauge Freight

The transportation for out-of-gauge freight,an important part in railway transportation,is of great importance to meet the transportation requirements in large national projects and building of the national defence.lt is always the master key for railway transportation to assure the transportation safety of out-of-gauge freight,improve transportation organization efficiency and avoid the interference for transportation.For some reasons,it still stays on the primitive methods with features of long time ,lower efficiency and much more mistakes. The level and the program for transportation for out-of-gauge freight are drawn through manual calculation and consulting references. And even there is the phenomena of increasing the limit level for guarantee transportation safety.The capability of transportation is seriously wasted .The transportation organization is interfered .The railway image and transportation benefits are infected loo. At the same time ,accidents occur more frequently in railway transportation for out-of-gauge freight in recent years .The leaders in each level pay much more attention on it .It is of great importance to develop computer-aided decision-making system on transportation program for out-of-gauge freight.After complete analysis on problems in transportation organization for out-of-gauge freight, this article systematically analyzes the transportation organization for out-of-gauge freight,introduces the performance, aim, principal in the design of computer-aided decision-making system transportation program for out-of-gauge freight (in 2 chapter).A deep study for system is carried out. It covers general structure, design in structure of data base , decision-making on car type, realization for loading detection, selection of limit level ,and also the realization of route safety detcction(in 5 chapter).It is the first time for railway transportation equipments GIS system to be applied in the route detection of car operation , which load out-of-gauge cargos. There will be come true for video management of cars which load out-of-gauge cargos (in 5.8 chapter). There are also studies on some improvements in system, for example, It is in gray-relationship decision -making theory that we can realize the selection of transportation program, simulated loading and automatic drawing of loadingprogram picture(in 6 chapter).This article studies the primitive technology on transportation for out-of-gauge freight.and also how to decide the level of freight beyond the limits.With the reference of achievements ,the decision on level of round out-of-gauge cargo is discussed(in 4.4chapter).
