利用影响图方法进行卫星应用效能评估

Appliance of Signed Digraph to the Efficiency Evaluation of Satellite Applications

影响图方法是一种规范化系统动力学建模方法,近年来被越来越多地应用于对复杂战争过程的建模之中.它体现了定性分析与定量分析相结合的建模思想,从实际系统出发进行建模,能够较真实地反映原始系统的特性,较好地反映出系统中的反馈和非线性的影响关系,并可以得到系统的状态方程,建立复杂战争过程的微分方程模型.讨论了影响图方法在卫星应用效能评估中的具体应用和数值仿真,分析了利用影响图方法对复杂现代战争过程进行建模的优越性,指出了应注意的几个问题.

Signed digraph is used to model the dynamic system problems. It is used more and more popular in the modeling of the complicate process of modern warfare. Signed digraph represents the combination of the quality analysis and the quantity analysis, and could better reflect the various influence relationships of the original systems, and to deduce the equations to model the whole process of the warfare. In this paper the applications and simulations of signed diagraph is discussed, especially about its use in the efficiency evaluations of satellite applications. Further more, the advantages and disadvantages of signed digraph are discussed the attentions are presented.
