Toward a better understanding of lead times in MRP systems
研究了MRP系统中提前期对积压、订单延迟和组件库存的影响，发现提前期变化有瞬态和稳态效应且方向可能不同，并提出了设定提前期的简单方法。
Abstract Lead times in MRP systems represent the planned amount of time allowed for orders to flow through the manufacturing system. Setting lead times is a major issue in the operation of MRP systems. There exists, however, very little documentation on just how lead times should be set. This study examines the effects lead times have on MRP‐based manufacturing logistics systems. In particular, it examines the effects that lead times have on backlogs, order tardiness, and finished component inventories. A major finding is that changes to the level of planned lead times have both transient and steady state effects that may not necessarily operate in the same direction. A simple methodology is presented for setting the level of planned lead times when the criterion is finished component inventory.
