摘要
正确有效的评价方法和反馈方法对于方案设计专家系统的质量是至关重要的。本文提出了评价子系统的基本模式,研究了评价数学模型和优化反馈模型,研制了建立评价子系统的工具软件E&F,并对该软件进行了应用试验。
The fundamental strategy adopted in an expert system for conceptual design is to carry out iteratively 'design-analysis-evaluation-redesign' until a 'satisfactory' scheme is arrived at. 'Evaluation and feedback-redesign' is obviously the key in such intelligent design strategy. The structure pattern of the evaluation subsystem and the basic methods for building an evaluation subsystem are suggested. The evaluation subsystem may generally consist of four parts: (a) the index system frame, an overall description of the design scheme; (b) the evaluation of the index parameters of the scheme; (c) giving an optional sequence of the feasible schemes by hierarchical fuzzy evaluation; (d) the optimization feedback model with which to provide information for further improvement of the redesign scheme. The program E & F (Evaluation and Feedback) and its application are presented. It is a tool software and has been successfully applied in software development of the evaluation subsystem in Wheel Loader General Scheme Design Expert System (WLGSDES). Numerical test results are found to be satisfactory.
