One of the main points of criticism on academic research in operations research (management science ) is that there is too much emphasis on the mathematical aspects of the discipline. In particular, the mathematical models that lend themselves to rigorous mathematical analysis are often rough...

The nature of the relationship Bill James found between the win/loss percentage of a Major League Baseball team and the number of runs the team scores and allows over the course of a season is investigated for the National Hockey League (NHL). We find the optimal form of James' model for the NHL...

This paper presents two operating rules for the refill and drawdown seasons of reservoirs in parallel for water supply, considering water quality. For the refill season a Linear Programming form of the New York City Rule is developed. Another Linear Programming form based on equalizing the...

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...

The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts...

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...
