Version Management Model of PDM Based on Multicolor-Map

Multicolor-Map is a mathematical tool in the field of simulation for discrete system. Through analyzing the current version management model of PDM, a new version management model based on multicolor-map was introduced in order to acquire the integrated product design information during the whole design process. It's significant in Product Data Management. Then the version set was looked as a multicolor-map set, and the arithmetic operators of the version management model of PDM were presented.
