Purpose

External factors such as improper handling, extreme weather and insect attacks affect product quality. It is most obvious in fruit products which have a high deterioration rate. Moreover, decaying fruits will increase the deteriorating of other good ones. The purpose of this study is to derive the optimal pricing and replenishment decisions for agricultural products considering the effect of external factors that induce deterioration.

Design/methodology/approach

In this paper, the study investigates ways to reduce the product deterioration rate by separating the near defective items from the other good products and accelerating the quick sales of the near defective items at a discounted price. The objective is to maximize the total profit by optimizing the selling price and the replenishment cycles. Two scenarios are investigated. In the first scenario, the retailer offers a selling price discount for near defective products to stimulate customer demand. In the second scenario, the retailer does not offer such discounts.

Findings

An algorithm to solve the model is derived. Further, numerical examples are developed to compare the total profit for the two scenarios. Theoretical derivations and graphical results show the concavity of the profit function. Finally, the sensitivity analysis shows that the total profit of the discount model is higher.

Originality/value

This study contributes to a new pricing and inventory decision model. The research provides insights to retailers on making optimal pricing and replenishment decisions for non-instantaneous deterioration items, as well as reducing the external factors that influence higher deterioration rate through separating good products from the near defective ones which are sold at a discount to induce the sale.

考虑恶化影响和定价政策的农产品非瞬时库存模型

目的

处理不当、极端天气和虫害等外部因素会影响产品质量。这在变质率高的水果产品中最为明显。而且，腐烂的果实会增加其他好的果实的恶化。本研究的目的是在考虑导致劣化的外部因素的影响下，推导出农产品的最优定价和补货决策。

设计/方法/方法

在本文中，该研究研究了通过将近似缺陷品与其他良品分开并以折扣价加速近似缺陷品的快速销售来降低产品劣化率的方法。目标是通过优化销售价格和补货周期来最大化总利润。研究了两种情况。在第一种情况下，零售商为接近缺陷的产品提供销售价格折扣以刺激客户需求。在第二种情况下，零售商不提供此类折扣。

发现

导出了求解模型的算法。此外，还开发了数值示例来比较两种方案的总利润。理论推导和图形结果显示了利润函数的凹度。最后，敏感性分析表明，折扣模型的总利润更高。

原创性/价值

这项研究有助于建立新的定价和库存决策模型。该研究为零售商提供了关于为非即时变质物品做出最佳定价和补货决策的见解，以及通过将优质产品与以折扣价出售的接近缺陷产品分开来减少影响更高变质率的外部因素，以诱导变质。销售。
