Towards the information content driven product model

One of the greatest challenges in engineering is development of products at extended companies using virtual spaces in system of systems environments. Engineers are forced to move their direct communication to indirect communication through product model. Tracking consequences of a change across a large and complex product model and considering intent of original decision maker at revision of an earlier decision have become two critical problems. This paper introduces methods for the solution of the above two problems in the implementation of model based product lifecycle management. After introduction of the problem, related researches and preliminaries of the reported research are given. Following this, a method is proposed for change management that applies dependency graph and change affect zone (CAZ). Next, information and information content based product modeling methods are compared and modeling is proposed for information content. Finally, implementation of the proposed methods in the form of extension of model based conventional product lifecycle management (PLM) systems is explained.
