| Summary: | 碩士 === 中原大學 === 工業工程研究所 === 94 === The Theory of Constraints (TOC) has been recognized as a very effective problem solving model, and it is used extensively in the business circles. The strength of TOC lies in its exploiting of common-sense and systematic thinking and employing of cause and effect analysis that it is apt to let people understand. However, TOC is found in practice to have some drawbacks. Namely, there are no objective mechanisms to choose one of key issues and prioritize important actions. Moreover, there are no evaluation mechanisms for effectiveness of problem solving. In essence, these drawbacks originate from the fact that the TOC model lacks an appropriate measurement scheme. Therefore, we choose to reconstruct a new problem solving model incorporating with the measurement concepts.
In this study, we firstly focus on building a goal-oriented TOC Problem Solving Model ,(1) incorporating customers’ focus point of views as seen in the Six Sigma methond,(2) the corporate goal linkage approach of CTQ in development of performance measurements, and also (3) the measurement mechanisms as proposed by the Analytic Network Process.
As to customer-driven, we made use of common tools to collect the Voice of Customers, i.e. the positive and negative perceptions of the problem in concern. The negative voices or undesirable effects serve as the basis of further problem analysis.
As to the measurement aspect, we set out from the whole voices of customers and developed a set of performance measurements to choose the key problem and of so the key solution set, by employing the Critical to Quality concept.
As to the evaluation aspect, we employed ANP as the vehicle for systematic calculation of weights in ratio scale, for use in prediction of the internal and external relationship among the criteria, goals, and schemes. Priority is thus assigned for decision making in finding out the key problem, key measurement indexes and also the key solution set.
Throughout the study, it is employed for a famous underwear company as the case study to explore management problems and the drawbacks of the TOC model ; and we also validated the integrated TOC model.
