Using Fuzzy Sets and Grey Decision-Making to Construct the Performance Evaluation Model of Firm’s Outsourcing Management – A Case Study of Avionics Manufacturer in Taiwan

摘要

This study aims to apply Fuzzy Set Theory and Grey Decision-Making to build a model for a performance evaluation of enterprise’s outsourcing activities. Moreover, the study took an avionics enterprise in Taiwan as a case study by using the two methods. Finally, the results were compared and discussed in details to conclude the suitability of the two methods. The study achieves the following conclusions: (1) the Fuzzy Set Theory and the Grey Decision-Making are effective methods for industries to evaluate the performance of outsourcing activities, and (2) in the case study the findings indicate that the Innovation and Quality categories are the most important weighting in outsourcing activities. Also, although the Fuzzy Set Theory and the Grey Decision-Making were applied (in other words, the calculation processes are different), the weighting sequences of evaluation indices have only a very few differences.
