概要 This paper presents a strategic approach for effectively differentiating the quality of a product from its competing products. The proposed approach utilizes quality function deployment (QFD) to capture customer requirements, technical requirements and quality characteristics of the product. The newly introduced technical requirements are concerned with the feasibility of the target quality (i.e., the target values of the quality characteristics) to be determined. Then, the approach adopts fuzzy logic to quantify the relationships between the quality characteristic values and the satisfaction levels of the requirements, and to evaluate the technical feasibility of the target quality. As a result, it becomes possible to capture the target quality determination for the product as a multi-objective optimization problem of enhancing the satisfaction levels of the customer requirements while ensuring the technical feasibility of the target quality. Then, in order to deal with this problem in a strategic way, the condition required for differentiating the product quality from its competing products is given. Further, a function which measures the extent of the differentiation is defined according to the preferences among customer requirements and which customer requirements are chosen as the order winning criteria for the product. Accordingly, the multi-objective quality planning problem is translated into a problem of maximizing the extent of the differentiation under some feasibility constraints. Finally, a simple example illustrates how the proposed approach works.
