Effectiveness evaluation method of multi-aircraft parallel test process

Abstract

The invention relates to an effectiveness evaluation method of a multi-aircraft parallel test process. The method comprises the steps of converting the multi-aircraft parallel test process into an aircraft test activity set, acquiring a consumption time, ending time constraint and occupied resource set of each test activity, creating a directed acyclic graph by adopting each test activity as a node and the consumption time of each test activity as an edge, acquiring a preset test activity set of each test activity according to the directed acyclic graph, and then calculating the test efficiency, the test activity coverage rate and the utilization rate of each resource; and finally calculating a process evaluation index and judging the test process according to the test efficiency, the test activity coverage rate and the gross resource utilization rate. Compared with the prior art, the method is indicative for quantitatively evaluating the index, the evidence for comparing the multi-aircraft parallel test process can be provided, an orientation can be provided for continuously optimizing the subsequent test process, and the multi-aircraft parallel test process efficiency can be integrally improved.

Description

technical field [0001] The invention relates to the evaluation of a comprehensive test process at the system level of a spacecraft, in particular to an efficiency evaluation method for a multi-spacecraft parallel test process. Background technique [0002] The spacecraft system-level comprehensive test is a comprehensive verification of the function and performance of the electrical equipment on the tested spacecraft during the final assembly and test phase of the spacecraft, including a series of engineering activities such as test design, test preparation, test implementation, and test summary. The key link to ensure the quality of spacecraft. The test cycle is generally long, and the process management is very complicated.

The test cycle is generally long, and the process management is very complicated

For a long time, the traditional spacecraft comprehensive test field lacks effective quantitative process evaluation methods. When there are not many spacecraft parallel test tasks, the demand for a single spacecraft test process and resource allocation optimization is not obvious, and decisions can be made by relying on intuitive judgment. The demand for quantitative evaluation of the testing process is not urgent
