Abstract: Supply chain for perishable product,an important branch of supply chain,is receiving more increasing attention,it is a crucial component for modern business.In this paper,on assumption that lead time is linear with respect to forecasting error andpiecewise linear with respect to crashing cost,inventory model of supply chain for perishable product with variable lead time under decentralized decision-making mode and centralized decision-making mode is investigated,the optimization algorithm is developed and the profits transferring of supply chain and supply actors is compared under this two decision modes.Furthey,the feasibility and conditions that achieves channel coordination for variable lead time supply chain under cooperative decentralized decision-making mode are discussed,and numerical examples are presented to illustrate the results of the proposed models.

Key words: perishable product, variable lead time, supply chain coordination
