Realization of constraint-based model of spatial layout design

Spatial layout design is a process of locating components in an available space while satisfying spatial relationships among the components, and the model of spatial layout design is used to determine the optimal locations of components in an assembly from spatial relationships between the components. Because of complicated constraints relations, the previous approaches cannot build an exact mathematical model for spatial layout design problems. This paper presents an approach that is constraint-based spatial layout design using a combination of solid modeling and optimization technology, and builds a model of constraint-based spatial layout design and describes the representation of constraints networks. This approach can overcome the above mentioned defeats. Moreover, the constraint-based model has been applied to the practical use of 'general layout design for heavy duty NC machine tools based on modular design technology' in 'Wuhan Heavy Duty Machine Tool Works (WHDMTW).'© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
