In an attempt to achieve a competitive edge, automotive companies operate global production networks to offer an ever increasing product variety, shorter and reliable lead times as well as competitively priced products. Cars are no longer exclusively produced based on standardized product...

The Vehicle Routing Problem (VRP) is one of the most studied problems in the field of Operations Research. Closely related to the VRP is the Capacitated Clustering Problem (CCP). The VRP can be considered as an 'extension' of the CCP in the way that for each cluster in the CCP solution,...

In this technical note we discuss a paper of Benkherouf and Balkhi recently published in Mathematical Methods of Operations Research. They established the model for deteriorating items with increasing demand and proved the uniqueness for the solution of the system of first partial derivatives....

Operations Research / Management Science (OR/MS) can be described as the discipline of applying advanced analytical methods to help making better decisions and has been around in the agricultural and forestry management sectors since the fifties, approaching decision problems that range from...

In this technical note, we consider the optimal replenishment strategies for a continuous review inventory model in which temporary price discounts are offered subject to supplier-obligatory restrictions on the special order quantity. We prove that the minimum inventory level during the on-sale...

Ancillary services such as those provided by logistics seem simple and straightforward, yet their role is often overlooked by hospitals. Recent studies indicate that logistics-related activities impact significantly on the quality of health care as well as on hospital costs. Hospital logistics...

This paper provides a review on the most relevant research works conducted to solve natural gas transportation problems via pipeline systems. The literature reveals three major groups of gas pipeline systems, namely gathering, transmission, and distribution systems. In this work, we aim at...
