Integrated Product and Process Development Mode Based on Models Coupling

Abstract

The coupling of product model and its development process model is very important to integrated product development. In this paper, the integrated product development architecture was established based on the detail analysis of coupling relations between product model and its corresponding process model, where the product data management system was viewed as the exchanging interface and operating platform of information. The integrated development mode by the coupling of product model main line and process model main line was presented. In this mode, both product model and process model are modified synchronously, and this modification is dynamic and mutual. The coupling mechanism between product model and its corresponding process model was established, and the algorithm was also given to evaluate the model coupling effect.

A Fuzzy Reliability Allocation Method for the Product Based on the Knowledge

“…In order to take the imprecision of human qualitative assessments into consideration, the five triangular fuzzy numbers are defined with the corresponding membership functions. The method was illuatrated detail in reference [7].…”

“…Defuzzification is implemented by joining the risk index to produce the final crisp numbers. The overall crisp comprehensive evaluation matrix is calculated as follows [7,8].…”

“…In this section, the weight set of each factor in the second layer can be obtained respectively according to the proposed method in reference [7] firstly.…”
