Abstract

The invention provides a multi-objective optimization scheduling method and system for remote-sensing satellite earth stations. According to the multi-objective optimization scheduling method, a complicated resource scheduling process can be refined and decomposed through five stages of screening processes such as ability screening, state screening, conflict screening, optimization screening and configuration screening so as to obtain a multi-objective resource scheduling result; and the optimization screening process can be designed on the basis of a weighted summation method so as to realizea multi-objective resource scheduling method architecture. Through the method and system, the using rate of resources of current earth stations and the balance of resource loads can be enhanced, andmeanwhile, the influences, on system task quality and task success rate, of performance differences between the resources are reduced.

Description

technical field

[0001] The invention relates to the application field of satellite ground stations, in particular to a multi-objective optimal scheduling method and system for remote sensing satellite ground stations. Background technique

[0002] With the development of aerospace technology and applications, more and more remote sensing satellites are in orbit at the same time, making the receiving resources of satellite ground stations face more and more serious multi-satellite scheduling conflicts. Therefore, it is of great significance to study the scheduling strategy and optimization method of multi-satellite equipment and realize the unified scheduling and optimal utilization of satellite ground station system equipment to improve the quality of space data transmission tasks and the use efficiency of ground station equipment.

[0003] According to the existing domestic ground station operation experience, the allocation of resources often adopts a first-come, first-ser...
