Abstract
In the product development process, customer requirements as well as constraints concerning the entire product life cycle have to be satisfied. Introducing the concept of Concurrent Engineering (CE), interdependencies of constraint sets increase due to the parallelization of activities. Constraint systems are used to attack this problem. Fuzzy Constraint Networks (FCN) have been introduced to expand the employment of constraint systems to the early phases of the product development process.
Aside of the ability to model and solve constraints of the product development process in a straight forward approach, the capability to handle disturbances (e.g. changes) is needed. In underdamped systems, changes are propagated through the entire system and therefore effect nearly all the decisions made. In this article, a possibility to reduce unnecessary propagation of changes will be discussed. Therefore, a two step application of Fuzzy Constraint Networks is introduced. The two steps consist of a straight forward approach, which takes advantage of the structure of product development processes using phases and milestones, and a stepwise backward propagation used to find valid solutions in case a change occurs.
