A Test Process Model and Optimization Framework Based on Network Schedule

Abstract

In order to shorten the test period of spaceflight articles at the launch site and improve facility utilization and launch rate, the paper proposes our research about test process model and optimization framework. The approach overlays test activity on activity-on-arrow for network schedule. The test process model is composed of the test network schedule. Based on the relativity of test items and input driving as well as output response, the test process optimization framework is formed. The test critical paths are dismantled and shortened as much as possible to shorten the entire test period. Through practice, our achievement effectively improves the test efficiency of flight articles at the launch site. It lays the foundation for constructing the integrated test system.
