基于单元关系度技术的Petri网模型分解--动态制造联盟网状组织结构优化的基础

针对动态制造联盟最小完备单元图的随机Petri网模型，提出单元关系度分解技术，为求解网状结构的解析式运行指标建立了基础，通过提出单元关系度的概念，计算得到关系度序号，在单元关系度的基础上，按单元不同业务功能关系的优劣次序，将最小完备单元图的单元进行分组，然后，根据不同组内单元之间其原来关系的最高出现频次进行组间连接，最后得到了针对动态制造联盟复杂Petri网模型的分解结果，为优化和改进Petri网系统的运行提供了更直观的控制途径。

Decompose complex Petri net based on degrees of cells'' relation-Basis of optimizing the web organization in dynamic manufacturing alliance

Based on the Petri net(PN) model of minimal complete cells graph(Min-CCG) in dynamic manufacturing alliance, a new technology that decomposes the complex PN is raised based on the degrees of cells' relation(DCR) in Min-CCG. The concept of degrees of cell's relation is put forward and the sequence number of DCR is created. Under the DCR, according to the business function priorities, the cells in the Min-CCG are grouped. Following that, the cell groups are linked by the frequencies of the original cell's relation. Finally, the full results of decomposition are obtained. This technology provides a base of getting the analytic solution that offers an intuitive and succinct approach to control the running in web organization.
