Dynamic-alliance-oriented manufacturing resources choosing model based on CBR

To organize an ideal dynamic alliance, choosing and optimizing manufacturing resources are very important. In this paper, a manufacturing resource choosing method based on CBR (case-based reasoning) was introduced. A method of calculating the similarity degree between the original cases and the retrieved ones was proposed, which was based on the combination of grey-relation theory and fuzzy-set theory. Thus, similar cases could be retrieved accurately, efficiently and quickly, and the accuracy of choosing efficient manufacturing resources was promoted greatly. Finally the way of how to establish manufacturing resource case library was discussed in the paper.
