DESIGN ACTIVITY MODELING IN DISTRIBUTED KNOWLEDGE RESOURCES ENVIRONMENT

Abstract

For the definition of knowledge flow, knowledge-flow control and knowledge-acquisition in integrated product design within distributed knowledge resources environment, this paper studies the structural modeling of design activity for integrated product design. The common features of integrated design in distributed resources environment are summarized as follows: centering on specific design requirements, organizing related design resources to perform design activities, outputting design results, carrying on value analysis of design results, and then making design decisions on the basis of value analysis. Based on the common features, a structural model of integrated design activities in distributed resources environment is built, which presents the structural expression of knowledge flow by defining the design requirements, the design resource input, the result output, the design activities, the relationship between the design activities, and the values of the design activities. Design activities at different levels are defined according to the design process models at different levels. A design activity that has been defined can be packaged into design components. The essence of integrated design lies in knowledge integration, which is to be realized by defining the input and output relationship between the design components and the knowledge components.
