This paper present a novel numeric SEA algorithm. Based on the universe principle of monotony, the hyperbox is applied to numerical approximation of mission locus. By a simulated token-ring method, the processing is dealt with parallelly. This algorithm minish the computation remarkably when searching the mission locus. Moreover, it gets over the limitation of depending on analytical function to get mission locus, thus makes it possible to get mission locus of complex systems. Then, the system evaluation model and analysis models for Moe indexes sensitivity and relation are presented. Finally this paper combines the algorithm and simulation means to analyse a notional anti-stealth-air-defense system. And the output is satisfying.
