RESEARCH ON VERSION BACKTRACKING IN COOPERATIVE DESIGN

摘要

Computer supported cooperative design is the evolution trend of traditional CAD. Because many agents participate in the design together, constraints are necessary to assure the cooperation. During cooperative design, design objects and constraints generated by them have many versions. On the base of a version management model, we propose an algorithm for version backtracking that minimizes the change on other design objects when a design object return to a previous version.
