Abstract:
The basic requirements of Concurrent Engineering, Logistics Design and three interdependency relationships such as uncoupled relationship, coupled relationship and decoupled relationship for the logistic design activities are presented in this paper. The coupled relationship plays an important role in concurrent product design process. To represent the precedence relationships among design activities, a directed graph is used to describe the design process. A Design Structure Matrix (DSM) illustrates the interdependency relationship between activities, which is the transpose of the accessibility matrix of the corresponding graph. Using the DSM, an algorithm of recognizing the coupled activities during the design process is presented. Moreover, an algorithm to figure out the order levels of activities during the logistic design process is proposed. Both algorithms are illustrated with a die design example.
