We describe a periodic review inventory system where emergency orders, which have a shorter supply lead time but are subject to higher ordering cost compared to regular orders, can be placed on a continuous basis. We consider the periodic review system in which the order cycles are relatively long so that they are possibly larger than the supply lead times. Study of such systems is important si...

Effective models of key operational decisions in multilocation inventory systems are important for a successful retail sector. This paper argues that much of the existing research in this area is not applicable to a highly competitive retail environment, particularly if periodic review replenishment policies are used. The paper develops a model of a periodic review multilocation inventory syste...

We examine a single-item, periodic-review inventory system with stochastic leadtimes, in which a replenishment order is delivered immediately or one period later, depending probabilistically on costly effort. The objective is to determine an inventory policy and an effort-choice strategy that minimize the expected total costs. Our analytical and computational analysis suggests that (i) a state-...

ABSTRACT This article explores the relationship between Universal Periodic Review (UPR) of United Nations Human Rights Council and temporality. In contrast to dominant understandings that view time as an external constraint or pressure acting on system—the UPR existing in time—I argue internal temporal logics underpin important constitutive ways. other words, is ontological feature UPR. ontolog...
