We consider the problem of precise estimation of service-level measures in multistage production-inventory systems when the system is managed for high levels of service. Precisely because the service level is high, stockouts, large backorders, and unfilled demands are rare and thus difficult to...

Joint ordering policies are examined as a method for reducing the transactions cost for multiple products sold by a seller to a homogeneous group of buyers. The problem of determining efficient joint ordering policies has the same structure as the previously-examined problem of determining the...

We explore the effect of dealing patterns on consumer purchase behavior by developing a normative purchase quantity model that can incorporate dealing pattern. The model adds to the stream of research on optimal purchasing policy by demonstrating how dealing patterns can be incorporated in a...

Empirical research indicates that some consumers form price expectations which may impact their purchase behavior. While literature in operations research has built purchase policy models incorporating uncertain price expectations, these models have been built for commodities. Consumers face an...

A production/inventory system is considered in which a single production facility produces items of a given type. The demand for the item is assumed to arrive according to a compound Poisson process. The time required to produce an item is assumed to follow an arbitrary distribution. An (s, S)...

In multi-echelon inventory systems that cover extensive geographical regions, emergency lateral transshipment between bases is commonly practiced to provide improved service support for products. In these systems, since neighboring bases are at shorter distances than to the depot, the base may...

The study focuses attention on a grouping procedure for the purpose of joint inventory replenishments from a single supplier. The grouping procedure exploits the group discounts available on the total purchase value of a group of index and the economies of scale of order placing costs. In...
