In this paper we compare three methods for the determination of the reorder point s in an (R; s; Q) inventory model subject to a service level constraint. The three methods di er in the modelling assumptions of the demand process which in turn leads to three di erent approximations for the...

In this paper we present an approximation method to compute the reorder point s in a (R; s; Q) inventory model with a service level restriction, where demand is modelled as a compound Bernoulli process, that is, with a xed probability there is positive demand during a time unit, otherwise demand...

In this paper we consider an inventory system with two suppliers.A supply agreement is made with one of the suppliers, to deliver a xed quantity Q every review period.The replenishment decisions for the other supplier are governed by a (R; S) replenishment policy; that is, when the inventory...

In this paper we discuss demand management problems in a multi-stage distribution chain.We focus on distribution chains where demand processes have high variability due to a few large customer orders.We give a possible explanation, and suggest two simple procedures that help to smooth demand.It...

This dissertation addresses the management of inventory systems. The thesis starts with an exposition on mathematical models that can be used in inventory theory. Then we deal with some information issues related to the demand process. Namely, how to control products that have intermittent...

The timely flow of financial information is critical for efficient capital market functioning, yet we have little understanding of firms’ and auditors’ collective abilities to maintain timely financial reporting while under duress. We use COVID as a stress test case to examine whether...
