For the problem of determination of maintainability quantitative requirements of equipment in demonstration phase, a model of tradeoff analysis of maintenance time is developed in this paper. Through the operational requirements analysis, the model of maintenance time of system level of equipment is determined. By constraint analysis, the models of maintenance time of levels based on design and maintenance concept constraints are presented. The model of tradeoff analysis that reflects maintainability quantitative requirements is established. The best matching between design concept and maintenance concept was achieved by tradeoff analysis with the model.
