Instrument optimization in parallel test system development

The increase of instruments could enhance the better test efficiency, which could lead to the increase of the parallel test system´s budget as well. To settle this problem, this paper proposed the instrument effectiveness model, and released seasoned engineers from arranging the instruments artificially. Firstly, to clarify the goal of parallel test system development, the efficiency of parallel test and the saving cost of instrument were construed. Secondly, introducing the stochastic theory into the test task scheduling field, static scheduling algorithm was designed, and efficient test sequences were got. Then, the instrument effectiveness model was proposed, which could meet different developers´ needs. At last, the feasibility and rationality of the model were validated by an instance of one parallel system instrument configuration, which could test three some-type UUT simultaneously. The instrument effectiveness model in this paper offers a fine measure to configure the instruments of parallel system, which could not only guides the engineers to develop parallel systems, but also offers similar problems a referential model.
