A model has been developed describing the expected costs of delivery and delay per period when demand for a certain repair part comes from more than one production line at a NARF. This model extends the earlier work by McMasters and Davidson on a schedules delivery model. The objective of the model development was the determination of the optimal number of periods between deliveries. This is that number N which minimizes the expected costs of delivery and delay per period. Unfortunately, no simple closed form expression for optimal N as a function of the other parameters could be obtained. As a consequence, parametric analyses of the cost function were conducted to determine optimal N and its behavior when other parameters were varied.
