Abstract

Demand-Driven Material Requirements Planning (DDMRP) was designed to improve supply chain performance in complex and uncertain environments. Literature on the topic suggests that production replenishment orders should be dispatched for execution based on the buffers’ penetration ratio of the products ordered, which is a measure of protection against stock depletion. However, the actual performance impact of this dispatching rule remains largely unknown as is the impact of different lot transfer policies. A simulation analysis was carried out to compare the performance of the lowest net flow position, the highest buffer penetration ratio, earliest operation due date and first-come first-served rules under synchronized and unsynchronized lot transfer policies. Results of our study show that the choice of dispatching rules is contingent on the setting of top-of-yellow and top-of-green, which determine the re-order quantity, and on the demand mix of products. The earliest operation due date rule shows great potential to outperform the rule typically applied in a DDMRP context specifically for a high demand mix. These findings provide important insights for improving industrial practice and for guiding future research on DDMRP.

DDMRP 生产执行的相对优先级:模拟评估
需求驱动的物料需求计划(DDMRP)旨在改善复杂和不确定环境下的供应链绩效。相关文献表明,生产补给订单应根据订单产品的缓冲渗透率来调度执行,这是防止库存耗尽的一种措施。然而,这种调度规则的实际性能影响以及不同批量转移策略的影响在很大程度上仍是未知数。我们进行了模拟分析,比较了同步和非同步批量转移政策下最低净流量位置、最高缓冲渗透率、最早操作到期日和先到先得规则的性能。研究结果表明,调度规则的选择取决于决定再订货量的黄顶和绿顶的设置以及产品的需求组合。最早作业到期日规则显示出巨大的潜力,特别是在高需求组合的情况下,它优于通常应用于 DDMRP 的规则。这些发现为改进工业实践和指导未来的 DDMRP 研究提供了重要启示。

期刊介绍: Operations Management Research is a peer-reviewed journal that focuses on rapidly publishing high-quality research in the field of operations management. It aims to advance both the theory and practice of operations management across a wide range of topics and research paradigms. The journal covers all aspects of operations management, including manufacturing, supply chain, health care, and service operations. It welcomes various research methodologies, such as case studies, action research, surveys, mathematical modeling, and simulation. The goal of Operations Management Research is to promote research that enhances both the theory and practice of operations management, as it is an applied discipline. The journal also publishes Academic Notes, which are special papers that address research methodologies, the direction of the operations management field, and other topics of interest to academicians. Additionally, there is a demand for shorter and more focused research articles in operations management, which this journal aims to fulfill.
