摘　　要：利用GSPN对计算机组装业的供应链进行了建模和性能分析。鉴于计算机组装业中配件来源的复杂性和多样性,本文对其供应链进行了简化,即把众多原配件供应商合并为一个大的供应商,从而使得GSPN分析的方法可行化。针对简化后的模型,我们建立了GSPN模型,并利用GSPN与马尔可夫链同构的思想对其进行了系统性能分析,指出了计算机组装业供应链系统在运营过程中出现的一些问题。In this paper,supply chain of computer packaging is modeled and analyzed based on GSPN. Due to the complexity and diversity of the spare parts used in computer packaging, this supply chain is simplified which treats the various spare parts suppliers as a single giant supplier and then the analysis based on GSPN approach is available. For the simplified supply chain, we give the GSPN model and analyze the performance of this model using the isomorphism of GSPN and Markov-Chain. Finally, the problem during the operation process of computer packaging supply chain is proposed according to some computations.
