Design of PDM Multi-Version Management Model Based on Polychromatic Sets Theory


Article Preview

Through analysis of the current version of relationship models, the paper presents the short points of them and develops a new PDM multi-version management model based on the theory of polychromatic sets with the concept and method of the theory introduced. This new PDM multi-version management model uses the element of polychromatic sets to represent the version of a document, a uniform color to represent the integrated attribute of object, and individual color to represent the property information of an object version respectively. Considering adjacent versions have too many identical contents, this new model introduces a method on difference information to reduce the storage space of multi-versions. Finally, the arithmetic operators of the version management model of PDM were presented through a related case.
