We consider the situation of a family of items sharing a common supplier or common production facility. There is a major setup (header) cost to make a replenishment of the family and a minor (line) cost for each item included in the replenishment. In such a setting it makes sense to coordinate...

We consider inventory policies for a continuous review system with discrete compound Poisson demand, convex holding-penalty cost and fixed order cost. Beckmann has showri that under these conditions (s, S) policies are optimal. We develop recursive formulae to calculate the cost for any pair (s,...

A style goods item has a finite selling period during which the sales rate varies in a seasonal and, to some extent, predictable fashion. There are only a limited number of opportunities to purchase or manufacture the style goods item, and the cost, in general, will depend on the time at which...

In this paper, we consider a periodic review order-up-to-level (or base stock) inventory control system under normally distributed demand. For such circumstances, an expression for the exact fill rate (fraction of demand satisfied without backordering) has been available in the literature, but...
