2002	Information Models of Design Constraints for Collaborative Product Development abstract Complex products and systems, like an aircraft, ship, or machinery plant, involve a large number of components which are arranged under spatial constraints/relationships in the design space. Current practices approximate these relationships. with simplified "dimensional constraints" aiming at formulating the design problem as a system of (in)equalities to be solved automatically, e.g., by a geometric-constraint solver This research proposes informationally-complete models for design-constraints based on an analysis of geometric and non-geometric properties of the related space volumes. Also, an extended product model is proposed describing the system's structure and components as well as related procedures and constraints to be used as a system life-cycle model.

1992	Solid/solid classification operations for recursive spatial decomposition and domain triangulation of solid models abstract Correct solid/solid classification operations are necessary for fully automatic discretization of solid models. The paper addresses this classification problem in the context of recursive spatial decomposition and domain triangulation. While, in the former case, solid/solid classification must be strictly based on the intersection operation, in the latter, a topological approach based on neighborhood information transfer is required.
