摘要

在传统的库存模型中,需求率通常被认为是一个常数,而在营销和定价中,需求率依赖于销售价格。本文提出了一种新的经济生产数量(EPQ)库存模型。这种生产-库存模型是使库存管理对管理者来说更加现实和实用的方面之一。EPQ库存模型包括定价策略、计划的缺货和返工过程。主要贡献在于,在EPQ库存模型中,价格是影响需求规模的关键因素,从而使总长期利润最大化。主要目标是确定最优销售价格、最优批量的离散值和最优缺货水平,从而使总利润最大化。为了实现决策变量的最优值,提出了一种算法。该算法为生产管理者共同决定批量、缺货量和销售价格提供了精确的解决方案。此外,利用实际工业数据进行了数值算例求解。结果表明,采用生产-库存模型获得的总利润较现状有显著提高。此外,还进行了敏感性分析,以描述所建议的生产库存模型的实际应用。

Optimization of price, lot size and backordered level in an EPQ inventory model with rework process
In traditional inventory models, the demand rate normally is considered as a constant value, while in marketing and pricing, it is dependent on the selling price. The present study introduces a new type of economic production quantity (EPQ) inventory model. This production-inventory model is among the aspects that make the management of inventories more realistic and practical for managers. The pricing policy, planned backorders, and the rework process are included in the EPQ inventory model. The main contribution is that, in the EPQ inventory model, the price serves as a critical factor that affects the size of demand to maximize total long-term profit. The primarily objective is to determine the optimum selling price, discrete values for the optimal lot size, and the level of optimal backorders so that the total profit is maximized. To accomplish the optimal value for the decision variables an algorithm is developed. The proposed algorithm provides an accurate solution for production managers to jointly decide on lot size, backorder size, and selling price. In addition, a numerical example is solved using real industry data. The results affirm that the total profit obtained using the production-inventory model increases significantly in comparison with the current situation. Furthermore, sensitivity analysis is carried out in order to describe the practical application of the suggested production-inventory model.
