The process of supply chain reengineering is divided into two parts here: structure reengineering and operation strategy reengineering. Multi-agent concept is adopted in the structure reengineering for the convenience of the modeling. Enterprises in the agile supply chain are expressed as corresponding agents with specified characteristics. Cost and response time are adopted as the main objectives of the global supply chain performance measurement. A virtual simplified supply chain is used to illustrate the role of overall supply chain performance measurement in the reengineering process.展开更多

Yunnan’s tea industry has the natur al resources and the economic effects envied, on the orther hand, Yunnan’s tea m arket has gradually become less and the economic effects have been poor. Through our comprehensive investigation and study, we consider that because the supply chain has seriously been disjointed among production, supply and sale of tea ind ustry in Yunnan, the supply chain of Yunnan’s tea industry need to be reorganize d for the promoting the development of Yunnan’s tea industry. The essence of reengineering of Yunnan’s tea industrial supply chain is to set u p the model of the trailed operation,to strengthen the strategic partnership man agement between the supply chain, to optimize the design of the supply chain and build up and improve the working mechanism for management of the tea industrial supply chain. The structure of Yunnan’s model of tea industrial supply chain: the model of com mercial flow; the model of logistics flow; the model of information flow and the model of cash flow. The solutions and policies for the reorganization of Yunnan’s tea industrial sup ply chain: planning, logistics and distribution and sales. Set up the supporting system of information technology. Build up the control system of production and planning.Improve the working mechanism of Yunnan’s tea industrial supply chain. Implement the engineering of exporting Yunnan’s tea into the markets of other p rovinces and foreign markets. Have many the channels that raise the funds of dev elopment for Yunnan’s tea industry.展开更多

Then the basic implementation principles are discussed, and the steps of BPR are also analyzed for Chinese logistics enterprises. Moreover, five relevant measures of ensuring the success of BPR for them are concept reengineering, system reengineering, organization reengineering, culture reengineering and technology reengineering.展开更多
