Abstract

In this article, we discuss a production-distribution inventory model with a single-vendor and single buyer under imperfect production process. Trade credit is offered by the supplier, who encourages the retailer to buy more products. The lead time and the vendor's setup cost are reduced by an added cost. Two models are proposed in this article. In the first model, the lead time demand is allowed to follow a normal distribution and another model is framed with distribution free lead time demand. The objective of this work is to frame the model under imperfect production process and delay in payment and to investigate the impact of product defective rate on the expected total cost of the integrated system. The optimal values of order quantity, lead time, setup cost and the number of shipments from vendor to the buyer are found. Efficient computational algorithms for both the models are designed and managerial insights are obtained.

具有贸易信用和不完全生产过程的两级供应链模型
本文讨论了不完全生产过程下单一供应商和单一买家的生产-分销库存模型。供应商提供贸易信用,鼓励零售商购买更多的产品。交货时间和供应商的安装成本因增加的成本而减少。本文提出了两种模型。在第一个模型中,交货期需求服从正态分布,另一个模型中,交货期需求服从无分布。本文的目的是建立不完全生产过程和延迟付款情况下的模型,并研究产品不良率对集成系统预期总成本的影响。找到了订单数量、交货时间、安装成本和从供应商到买方的发货数量的最优值。为这两种模型设计了有效的计算算法,并获得了管理见解。
