Study On The The Fundamental Subjects Of Instant Simulation During The Design Phase Of Factory Railway

Industrial factories railway transportation system is a relatively independent transportation system, the system has a small scale, line rail transportation and dense, combining the characteristics of production, domestic production stage in study of the railway transport simulation obtained some achievements, to fully tap potential, enhance the transport equipment capacity, reduce transportation cost has certain practical significance.Based on the design phase of the industrial factory rail transportation network real-time simulation as a starting point, and the expectations for the design phase, found that factory network bottlenecks, optimize network structure factory.This paper studies the industrial factories in the two main railway transport simulation based problems, one is the basic theory and according to chart a production function different covers road network and another is grading theory based on established hierarchical network model, and then puts forward the region in search of the shortest path between and partitions for rapid shortest path algorithm, and realize the shortest path to go do.First studied CAD drawings of railway sections on realizing factory line network information extraction technology, then puts forward the integrity of the hierarchical network keep matrix method, the model is established with program realization network information quickly retrieve and establish grading road adjacency matrix and weighted matrix; Finally the algorithm for grading path is the program realization. Taking a retrofit design of the steel for example, have examined the foundation of molten iron simulation program is practical.This article for design phase factory railway real-time simulation provides basic paper puts forward basic network problems and the shortest path problem, after the procedure for the further development of algorithm provides the basis.
