We consider the inventory control problem of an independent supplier in a continuous review system. The supplier faces demand from a single customer who in turn faces Poisson demand and follows a continuous review (R, Q) policy. If no information about the inventory levels at the customer is...

This paper provides a new decision rule for emergency replenishments in an inventory system. The decision rule is a generalization of a previous decision rule suggested and evaluated in Axsäter (2003, 2007). An improvement step is added to this rule and this often means considerably better...

In equipment-intensive industries such as truck, electronics, aircraft and dredging vessel manufacturing, service parts are often slow moving items for which the transshipment time is not negligible. However, this aspect is hardly considered in the existing service logistics literature. In this...

This paper considers a single-echelon, continuous review, inventory system with a warehouse facing compound Poisson customer demand. The replenishment lead-time is constant. Demand that cannot be met directly is backordered. There are standard linear holding and backorder costs but no set-up or...

This paper compares installation and echelon stock policies for multilevel inventory control. The major results are for serial and assembly systems. For (Q, r)-rules, echelon stock policies are, in general, superior to installation stock policies. A Kanban-policy is identified as a restricted...

The classical dynamic lot size problem without backlogging is in practice usually solved with the aid of various heuristics. Most heuristics are sequential techniques, i.e. the future demand is considered period for period, and a decision whether to have a set-up or not in a certain period is...

A continuous review serial production/distribution system with discrete compound Poisson demand for the end product is considered. Unmet demand is back-ordered. Production/transportation times are constant. All deliveries from one stage to the next must be multiples of given batch sizes. We...

This paper deals with the classical dynamic lot size problem without backlogging and capacity limitation. We derive worst case performance bounds for a class of lot sizing heuristics. When the considered methods are applied a decision whether to have a set-up or not in a certain period is taken...

In a recent paper, Cetinkaya and Lee (2000) model integrated inventory control and shipment scheduling in connection with vendor-managed inventory (VMI). The model is optimized by an approximate technique. This note provides a simple procedure for exact optimization, and illustrates that the...

In inventory systems with several bases that support different geographical regions, it is quite common to allow emergency lateral transshipments between the bases. This may be advantageous if neighbouring bases are at shorter distances than the central depot or the external supplier. This paper...
