Relativity-Driven Optimization for Test Schedule of Spaceflight Products at Launch Site

The test preparation of flight products determines the length of the entire cycle from flight products entering the launch site to launch. The improvement of test efficiency is beneficial to the launch efficiency of the launch site. According to the test scheduling plan of flight products at the launch site, we propose test scheduling model based on related data-driven optimization and superimpose test elements on the test network schedule diagram. By means of the correlation between test item input, excitation and output response, the optimization strategy of test process was proposed to decompose and shorten the critical path on test network schedule. The strategy shortens the test cycle of flight products. Through practice, integration testing and good results have been obtained.
