摘要
基于案例推理的型号研制项目风险评估系统,其案例推理包括风险案例录入、案例检索计算、相似案例匹配、用户确认及更新风险案例。系统使用相似性隶属度算法,对风险案例库中的案例进行相似案例检索计算。即首先对相似性主、客观因素分别进行相似隶属度分析,再将各因素的相似隶属度进行合成,最后与事先确定的阈值进行比较,由此判断出相比较装备是否相似。
The project risk evaluation system of model development is based on case reasoning. The case reasoning includes risk case input, case search calculation, similar cases matching, user confirming and renewing risk cases. The system adopts similar subjection degree algorithm to carry out similar case search calculation for risk case base, that is, respectively carry out the similar subjection degree analysis for objective and subjective factors of similarity, and then, compose similar subjection degree of every factor. At last, the composition results are compared with the threshold value to judge the similarity of equipments.
