Abstract:

As the normality of spacecraft launch with highfrequency and an improvement in reliability of space products, using the scheduling mode of parallel multitask to improve the usingrates of launch resource is an objective requirement. To avoid launch system deadlock caused by stochastic iteration of mission processes, the paper constructs the mechanism of forecasting deadlock and evaluating losses, establishes the object function of integrating minimizing completion time and minimizing total weighted tardiness time, designs a parallel scheduling model of multitask, develops a scheduling optimization algorithm of several group agents working together, and verifies the feasibility of the model and algorithm by an example. The application effects of the model and its algorithm in launching “Tiangong1” and the “Shenzhou8” are better.
