Six Sigma Project Selections by Using a Fuzzy Multi Criteria Decision Making Approach: a Case Study in Poly Acryl Corp

Six sigma may be named as a powerful and comprehensive management tool which is necessary in order to bring changes in organization and to make conformity with customer needs. Despite of other quality approaches, six sigma is not only a method, but it contains a vision, a goal and a symbol. Beside the six sigma, symmetrical valuation method is interpreted as a tool to collect strategy. This system offers a method to converge occupation's activities with strategy, and also it offers a method in order to watch the operation of strategic goals during time. Undoubtedly, the first step in reducing the risk failure of the six sigma projects is to select the optimal choices. In this paper, the effectiveness of criteria in choosing six sigma projects are identified and defined. Moreover, a case study in Poly Acryl Corp is illustrated to demonstrate the effectiveness and practicality of the fuzzy multi-criteria decision making approach to select six sigma projects. In fact, we evaluated how selecting six sigma projects and goals using the fuzzy multicriteria decision making technique affect the organization.
