We study the tradeoff between efficiency and service quality in tandem systems. We reward efficiency by assuming that a revenue is earned each time a job is completed, and we penalize poor service quality by incorporating positive holding costs. We study the dynamic assignment of servers to tasks with the objective of maximizing the long-run average profit. For systems of arbitrary size, genera...

W introduce and analyze a model that explicitly considers the timing effect of intertemporal pricing— the concept, found in practice, that demand during a sale is increasing in the time since the last sale. We present structural results that characterize the interaction between the decision to hold a sale and the inventory-ordering decision. We show that the optimal inventory-ordering policy is...

In this article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. The order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. In addition, storage space is constrained and the problem...

of network pricing. We collected data to empirically model the workload. The data shows temporal locality of reference in all traces. LRU based holding time policies use this temporal locality eeectively and perform better than any other strategy examined. To our surprise, timer based schemes perform poorly. However, the LRU-delay scheme, which corresponds to a xed system-wide timeout, is eeect...

In a personal communication service (PCS) network, the call completion probability and the effective call holding times for both complete and incomplete calls are central parameters in the network cost/performance evaluation. These quantities will depend on the distributions of call holding times and cell residence times. The classical assumptions made in the past that call holding times and ce...

The paper is to present a simulation method to search for an optimal (z, Z) (z < Z) values for the (z, Z) production control policy so that the expected inventory cost rate (i.e. expected total cost due to both inventory holding and backlog per unit time) is minimal for a single machine system with buffer. The system is subject to operationdependent failure only and alternates between normal an...
