Development of products in the competitive industries uses modeling, simulation, product data management, and Internet portal based systems for lifecycle management of product information. Engineering has been elevated to a high level. However, new problems have been emerged in practical application of this virtual technology. The product model basically consists of definitions for engineering objects and their relationships. As a new problem, high number of unorganized relationships makes handling of changes in large product models difficult or even impossible. The authors analyzed this problem and proposed a method as a contribution to one of the possible solutions for that problem. Most important elements of their findings are published in this paper. In Chapter 2, they discuss product development in virtual space, emphasize critical issues, and cite relevant research results. In Chapter 3, they explain their new method for organized management of dependencies in large product models. Chapter 4 introduces a new method for the extension of classical product model to content of model information. Finally, Chapter 5 is a short introduction to the implementation of the proposed modeling in professional systems for lifecycle management of product information.
