【Abstract】 In order to improve the combinatorial optimization performance of resource scheduling for high-tech virtual enterprise,the correspondences between the resource transport sequence and the timed Petri net was investigated by serial scheduling rule and ant colony optimization algorithm to establish the model of resource scheduling for high-tech virtual enterprise,and the calculation formula of the scheduling model was obtained.An example was taken to illustrate the application of the resource scheduling model.It is proved to be more effective and accurate by compared with the results gained by the scheduling methods of minimal time and time-cost tradeoff.At the same time,it also avoids many man-induced factors.The achievements above solve the problem of resources configuration optimization for high-tech virtual enterprise,which is very significant in theory and reality.更多还原
