摘要
对已有变更案例进行检索是制订新变更解决方案的有效手段,研究并提出了一种基于本体的制造企业工程变更案例检索流程和检索方法。首先在建立近似词词库、变更案例本体的基础上,提出了变更案例检索的四个步骤;其次,研究了变更案例检索的算法表达和相似度计算方法;最后以汽车底盘零件的变更案例为实例验证了算法的有效性。
It is an effective approach to achieve solution for new engineering change by retrieving solutions of existing engineering change cases. This paper proposed a method based on ontology to retrieve engineer- ing change cases in manufacturing enterprises. Firstly, synonyms thesaurus and change case ontology were firstly developed and four retrieving steps were presented. Then change case algorithm expression was stud- ied as well as similarity calculation method. Finally, case study on car chassis component change verified the effectiveness of the algorithm.
