This paper introduces a methodology for the organization of dependencies in classical product models. The reported work is intended as a contribution to the solution of the problem of tracking associative connections along chains of modeled product objects at analysis of consequences of changes of modeled objects during development of products. The author proposes an information content oriented extension to classical data oriented product models. Tracking of consequences of changes of modeled objects on other modeled objects is assisted by concepts of change affect zone and change chain. The approach to model construction process is based on modification of a previous state of the model for development of the product. This paper starts with an outline of engineering in virtual space as well as relevant researches from the author and the literature. Following this, the proposed extended modeling is explained concentrating on change affect zone and change chain. Next, information content oriented product model and its connection with classical data oriented product model are detailed. Finally, possibility of implementation of the proposed modeling in professional product lifecycle management (PLM) systems is discussed.
