Abstract: In the distributed parallel computing environment based on MAS，some new characteristics has brought forword to the Task Scheduling.Aimed at task scheduling in distribution fast simulation and modeling that is based on MAS，develope a new model for Task Scheduling；Propose a new heuristic task scheduling optimization algorithm based on fuzzy C-means clustering algorithms.This algorithm not only has linear time complexity，but also gets near-optimal solution or optimal solution stably，and significantly improves the performance of masDSE.This conclusion is proved by large number of case test.
