In this manuscript, a model is proposed for the inventory planning problem with items which deteriorate linearly with respect to time. The concept of salvage value for deteriorated items is considered and incorporated in this model. The solution procedure of proposed optimization model is illustrated by a couple of numerical examples. A convexity check of the average total cost function is performed by plotting a two dimensional graph. The sensitivity test of the proposed model is performed to study the effect of changing the least as well as the most sensitive parameters in the proposed optimization model. Some graphical representations are constructed to discuss the outcomes and results so obtained for a choice of various parameters

具有残值的时变线性需求和抛物线持有成本的库存计划问题

在此手稿中，提出了一个针对库存计划问题的模型，该模型的项目随时间线性恶化。考虑了变质物品的残值价值概念，并将其纳入该模型。几个数值示例说明了所提出的优化模型的求解过程。平均总成本函数的凸度检查是通过绘制二维图来执行的。对所提出的模型进行敏感性测试，以研究改变所提出的优化模型中最小和最敏感参数的影响。构建一些图形表示形式来讨论选择各种参数所获得的结果和结果
