Research on Technology of Rough Set-Based Conflict Solution Case Reasoning in Collaborative Design

For resolving the problem of conflict solution case reasoning in collaborative design, this paper presents a rough set-based conflict solution case retrieval strategy, and gives the method and algorithm to computing the weight and reduction of the case feature attribute by applying rough set theory. The reduction result is taken as the index of the case knowledge base to retrieve original cases which are correlative with the target case, and by using a method measuring similarity to retrieve original cases which have the max value of similarity degree, for providing reference to resolve conflict of the target case. Finally, the availability of this retrieval strategy is demonstrated by analyzing an application illustration
