System compartition and module sorting algorithm of diagram configuration simulation software

System compartition and module sorting algorithms of diagram configuration simulation software were proposed. The introduced system compartition algorithm is the tree-searching algorithm based on adjacent matrix, and this kind of algorithm can be easily applied by programming. For the simulation systems which include many loops, the loops can be quickly found out, and the input/output relation between the modules in the loop can be also recorded. Two different sorting algorithms were discussed, one is based on the number of the unknown inputs, the other is based on the distance between input module. Comparatively, the second algorithm is much simpler, because it doesn't care about the number of unknown inputs. The sorting results of the two different sorting algorithms may be different. Finally, the efficiency of the algorithms was proved by analyzing a specific configuration simulation system.
