Abstract

The invention discloses a method for allocating satellite concurrent testing resources based on a genetic algorithm. The method comprises four steps of: defining the stability and the total time limit of a resource allocation scheme; solving a dual-objective scheduling model of the allocation of the satellite concurrent testing resources by adopting a non-dominated sorting genetic algorithm (NSGA-II) to obtain a non-dominated solution set; solving the dual-objective scheduling model by adopting an optimal solution filtering algorithm to obtain an optimal resource allocation scheme; and finishing a design. The method for allocating the satellite concurrent testing resources based on a genetic algorithm in an uncertain environment is provided by the invention to obtain a stable resource allocation scheme, so that limitations of the conventional method for allocating the concurrent testing resources are overcome, the aim of optimal allocation of the satellite concurrent testing resources is fulfilled, the test efficiency is improved, and the test cost is reduced. The method has a good practical value and a wide application prospect in the technical field of an aero-space concurrent testing technology.

Description

Technical field [0001] The invention involves a satellite parallel test resource allocation method based on genetic algorithms, especially a satellite parallel test resource allocation method based on genetic algorithms in uncertain environment.The present invention belongs to the field of aerospace parallel test technology. Background technique [0002] In recent years, my country's aerospace technology has developed rapidly, and aerospace technology has begun to expand rapidly from the national defense military field to the civil aerospace field. The number of satellites owned by my country has increased sharply, and the development and production of satellites have begun to enter the stage of mass.The traditional satellite test uses a serial test method -low test efficiency, low resource utilization and high test costs.This test method can no longer meet the requirements of satellite mass production.In this case, it is urgent to change the existing satellite test mode and achi...
