基于粗糙集的信息共享度评价研究与实现

Research and implementation of Evaluation Model for Information Sharing Based on Rough Set Theory

对供应链信息共享度进行评价可以找出供应链信息流的瓶颈。针对传统评价方法存在的指标冗余和权重主观性的问题,采用粗糙集的差别矩阵来约简评价指标,运用属性重要度来确定指标权重,构建了信息共享度评价模型。结合模糊评价方法的一个算例,证明了模型的可行性和科学有效性。采用Web Services技术开发了供应链信息共享度评价Web服务平台,运行效果良好。

The ＂bottleneck＂ of supply chain information flow can be found by evaluation of Information Sharing of Supply Chain Management.In view of the redundancy of indexes and subjectivity of weights comparing to traditional evaluation models,discernibility matrix and attribute importance in rough set theory is introduced to simplify the indexes and to calculate weights,and an evaluation model is established.Then an applied case is given to show the efficiency and practicability of the model.A web service-based platform is developed for serving to all companies in the supply chain,running well.
