【摘要】：在供应链管理研究中,库存管理相关研究一直占据重要位置,合理的库存决策不仅可以降低库存成本还能提高服务质量和企业声誉,是企业正常运营和发展壮大的重要环节。报童模型是库存问题的经典模型,但有学者发现报童模型理论研究的决策与实际决策情况并不相同,这是由于决策者受到风险偏好等主观因素的影响。现有考虑风险偏好的库存管理研究中,学者们大都假设产品残值为0或者签订回购契约,考虑产品清仓处理的研究较少,为使研究更加与实际贴合,本文将剩余产品清仓处理的收入考虑进来,研究零售商风险偏好对库存决策的影响。本文用缺货成本与库存总成本的比例动态地划分风险偏好,在考虑清仓收入的基础上,建立供应商、零售商的期望利润目标函数,研究了二级供应链中考虑零售商风险偏好的库存决策问题,并探讨零售商风险偏好与最优订货量、最优批发价的关系。理论推导和算例分析表明:当清仓价格固定时,最优订货量、供应商最优批发及其期望利润、供应链的期望利润等都随着零售商风险偏好度的增加而增加,零售商的期望利润随着零售商风险偏好度的增加而减少;当清仓价格与销售剩余量相关时,随着零售商风险偏好度的增加,最优订货量、优批发价及他们的期望利润、供应链的期望利润等都相应增加。
[Abstract]:In the research of supply chain management, the research on inventory management has always occupied an important position. Reasonable inventory decision can not only reduce the cost of inventory, but also improve the quality of service and the reputation of enterprises, which is an important link for the normal operation and development of enterprises. Newsboy model is a classical model of inventory problem, but some scholars have found that the decision-making of newsboy model is different from the actual decision, because the decision maker is influenced by subjective factors such as risk preference. In the existing inventory management research considering risk preference, most scholars assume that the residual value of the product is 0 or sign a repurchase contract. This paper takes into account the income of surplus product clearance, and studies the influence of retailer's risk preference on inventory decision. In this paper, the risk preference is dynamically divided by the ratio of stock shortage cost to total inventory cost, and the objective function of expected profit of suppliers and retailers is established on the basis of considering the clearing income. In this paper, the inventory decision problem considering retailer's risk preference in secondary supply chain is studied, and the relationship between retailer's risk preference and optimal order quantity and optimal wholesale price is discussed. The theoretical derivation and example analysis show that the optimal order quantity, the optimal wholesale and expected profit of suppliers, and the expected profit of supply chain increase with the increase of retailer's risk preference when the clearing price is fixed. The expected profit of the retailer decreases with the increase of the retailer's risk preference; when the clearance price is related to the sales surplus, as the retailer's risk preference increases, the optimal order volume, the optimal wholesale price and their expected profit are obtained. The expected profit of the supply chain increases accordingly.
