摘要

摘要: 根据大型复杂装备研发周期长、耗资大、风险大的特点,引入前馈控制机制,建立了大型复杂装备研发项目成本控制专家系统的体系结构,同时以该体系结构为主体,给出专家系统的知识表示及推理机的一种实现方法,最终使得知识库和推理机得以独立实现.实现后的系统以知识库和专家系统相结合的方式对装备研发成本进行实时监控和预测,对于输入的问题,系统经过推理后给出相应的参考建议,为成本管理智能化提供可行依据.由于知识库和推理机是相对独立实现,因此该系统相对传统专家系统来说具有更好的可维护性和可靠性.

Abstract: Because the research and development of complex equipment have a long cycle, cost too much and are high-risk,a cost control structure of large scaled complex equipment development according to the feed-forward control was presented. At the same time the method of knowledge representation and inference engine were given based on this structure,which enabled the knowledge base and inference engine to be realized independently. This system could make real-time monitor and prediction of manufacturing cost with the application of cost control system and knowledge management system. For the input problem, the system gave decision support to administrator after reasoning, which offered a feasible basis for the realization of intelligent management on research cost. Because the realization of knowledge base and inference engine was relatively independent, this system had better maintainability and reliability compared to conventional expert system.
