| In research on supply chain management,inventory management research has been occupying an important position,and a proper decision on the inventory can not only reduces the inventory management cost but also improves the service quality and corporate reputation,so inventory management is an important part of enterprise operation and development.The newsboy model is a classical model of inventory problem,but some scholars found a big difference between theoretical research and the practical research.In the existing studies on inventory management considering risk preference,scholars assume that the residual value of products is 0 or exist a buyback contract,and small number of the studies considers product clearance.In order to make the research more practical,the paper takes the dump clearance revenue into account to investigate the influence of retailer’s risk preference on inventory management decision.The paper measures risk preference by the proportion of shortage cost and total inventory cost,considering dump clearance revenue,setting up the expecting revenue functions of the supplier and retailer,researching the ordering and pricing problem in a two-echelon supply chain when the retailer’s risk preference is considered and discussing the relationship between the retailer’s risk preference and the optimal order quantity,optimal wholesale price.The theory derivation and numerical solutions analysis shows :when the clearance price is fixed,the optimal order quantity,the best wholesale and supplier expect profits suppliers,the optimal order quantity and supply chain total profit under the circumstance of centralized decision-making all increase with the increase of the degree of retailer risk preference,the retailer’s expected profit decrease with the retailer risk preference degree increase.When the clearance price is influenced by the quantity of the remaining products,the optimal order quantity and the optimal wholesale price and their expected profits of supplier,expected profits of the supply chain under centralized decision-making etc all corresponding increase with the increase of retailers’ risk preference. |
