面向订货生产的生产计划与控制技术

生产负荷控制是一种面向订货生产方式的生产计划与控制技术．它以输入输出控制为基本思想，通过设置订单交货期和控制订单进入生产车间的时间以及调整机器生产能力来控制各台机器的生产负荷，能够降低在制品库存，控制生产提前期并改善交货表现，从而增强制造企业的竞争力．本文介绍了生产负荷控制技术的理论、控制结构，并综述了相关研究文献，提出了今后的研究方向．

Production Planning and Control Approach Suitable for MTO Manufacturing

WLC is a hierarchical production planning and control approach for job shop manufacturing, and suitable for make-to-order industry. Based on the theory of input/ output control, the principle of WLC is to control the length of the queues in front of each work station through assigning due date and controlling the release time of each oder, and also by adjusting the capacity of machines. It enables the manufacturing companies to reduce WIP and lead time, and improves delivery performance, which strengthens their competitive advantages. The paper introduces WLC principles and control structure, and presents a review of relevant research papers. Finally, some promising research paths are proposed.
