We study an inventory system controlled by a base stock policy assuming a compound renewal demand process. We extend the base stock policy by incorporating rules for degrading the service of larger orders. Two specific rules are considered, denoted Postpone(q,t) and Split(q), respectively. The...

We develop an algorithm to compute an optimal Q(s,S) policy for the joint replenishment problem when demands follow a compound correlated Poisson process. It is a non-trivial generalization of the work by Nielsen and Larsen (2005). We make some numerical analyses on two-item problems where we...

The acceptance of income differences varies across countries. This article suggests three general mechanisms to account for this: the “tunnel effect”, related to perceptions of generational mobility; the “procedural justice effect”, related to the perceived fairness in the process of...

Whether women should be oriented towards the family or towards the labour market is one of the crucial questions individuals, families and societies face. Previous cross-national data indicate large cross-national variations even within the European countries. In some societies, especially in...

We consider an inventory system, operated by a base stock policy and serving two customer classes. One customer class, Class 1, does not provide any advance demand information at all, while the other, Class 2, does. In order to reward a customer of Class 2 for providing advance order...
