Abstract:

Aim at the problem of sensitivity analysis and parameters optimization for equipment maintenance support simulation system, the application research framework based on the simulation experimental means is proposed. In analyzing the simulation system modeling method basis, the obtaining method of the input parameters based on simulation entity is proposed. At the same time, the simulation output parameters is determined considering the operational readiness, sustainability and maintenance support system level.The key inputs screening method based on sequential bifurcation, and the sampling experimental design method of the inputs based on the orthogonal array are studied. The sensitivity analysis principle based on the range analysis and variance analysis is researched. On the basis of variance analysis, a new method of input parameters optimization is proposed.Finally, the software tool developed for sensitivity analysis is used to do an practical example. The result shows that the methods proposed above are of good engineering value.
