|Job Rotation Using the Multi-Period Assignment Problem
||This paper addresses the current gap in the literature on quantitative tools that enable a manager to build schedules which incorporate job rotation by employees. This is done within the framework of the well-known Assignment Model recast in a multi-...
|Joint Economic Selection of Target Mean and Variance
||This paper considers the problem of selecting the most economical target mean and variance for a continuous production process. In earlier studies, many authors considered the problem of finding an optimal target mean assuming that the variance is kn...
|A Location-based Comparison of Health Care Services in Four U.S. States with Efficiency and Equity
||This paper examines the efficiency and equality in geographic accessibility provided by hospitals. We use the criteria efficiency, availability of the service, and equality. Quantitative measures are defined for all criteria, and are measured using a...
|Maximizing Workforce Diversity In Project Teams: A Network Flow Approach.
||Several social, economic and political factors have contributed to the increasing diversity of today's workforce. In addition, in an era when organizations are continuously redesigning their work and restructuring their operations to achieve their go...
|On the interaction between indirect cost allocations and the firm's objectives
||The import of cost allocation procedures are through their ex ante impact on decision making. Hence, it is important that the allocation issue be placed squarely within the context of those firm's objectives which gave rise to the need for the specif...
|On The Use of Genetic Algorithms to Solve Location Problems
||This paper seeks to evaluate the performance of genetic algorithms (GA) as an alternative procedure for generating optimal or near-optimal solutions for location problems. The specific problems considered are the uncapacitated and capacitated fixed c...
|An Optimization-based Framework for Modelling Counter-terrorism Strategies
||This article introduces the subject of terrorism and counter-terrorism by means of a two-person bimatrix game that provides some insight into the behaviour of the two players. We then examine three important areas in counter-terrorism tasks: the dete...
