碩士 === 逢甲大學 === 工業工程學系 === 89 === Recently, Facing the global competitions, the concept of concurrent engineering is widely applied in the development of a new product. This study is focus on the new product developing stage and the issues regarding process planning. In most of previous studies, the Process Capability Indices (PCI) was only used to measure quality of the on-line products. Few were focus the off-line products. The study uses the PCI with cost effectiveness to set up the process planning and to predict the good quality rate for a new product in the product designing stage. The company could introduce the new products to the marketplace as soon as possible and would be able to take cost and quality into account. As a result, the new products will have the attributes of quick release, low cost, and high quality. From this study, we are able to get the optimization process tolerance of the PCI with cost effectiveness when we use the new method of process planning by putting the cost factor into the PCI. This approach could avoid the impact on optimization process planning while there is estimation error on parameter K on quality loss function. It also approves that the PCI could be appropriately applied on the off-line product design and planning and get the optimization process tolerance.
