System conceptual design mainly utilizes automated tools based computer to accomplish the design of weapon system while reducing time and lowing cost , and evaluate the combat effectiveness of weapon system in simulation environment . nevertheless as far as it goes the improvemeni of efficiency of weapon system design is even not poor but limited and far behind the amicipaton considering the cost put into this field with the light of advanced compllter tool . the main reason is the complexity and difficulty of interaction arnong users and models from different discipline
但就目前的总体概念设计的应用现状而言，先进的计算机辅助设计或分析工具的引入，对于总体概念设计效率的提高并没有预期的那么显著，其原因在于：武器系统总体概念设计过程是一个复杂的多学科多用户协作的迭代反复过程，在提高了部门自动化水平后，整个总体概念设计效率提高的瓶颈在于不同学科领域、不同设计人员、不同工具及模型之间交互的困难。
