The article presents a framework for modeling and evaluating product design problems in a computer network-based design environment. The goal is to create integrated design models for collaborative work, improving product quality, and reducing development time. The approach involves using modules to represent different aspects of the design problem, which interact through services for information exchange. This method allows for specialized engineering applications and design models to work together in a common environment. The researchers extended this approach to create a distributed object-based modeling and evaluation framework for design problems.
