Centralized Resource Allocation Using Data Envelopment Analysis
While conventional DEA models set targets separately for each DMU, in this paper we consider that there is a centralized decision maker (DM) who “owns” or supervises all the operating units. In such… Expand

In this paper, a linear model is presented and used to study the cost savings that different companies may achieve when they merge their transportation requirements. Expand
Data envelopment analysis of integer-valued inputs and outputs
This paper addresses DEA scenarios whose inputs and outputs are naturally restricted to take integer values. Expand
Slacks-based measure of efficiency of airports with airplanes delays as undesirable outputs
This paper reports the slacks-based measure (SBM) of efficiency of 39 Spanish airports for years 2006 and 2007. Expand
Metaheuristic optimization frameworks: a survey and benchmarking
This paper performs an unprecedented comparative study of Metaheuristic optimization frameworks. Expand
Machine cell formation in generalized group technology
In this paper, we study the configuration of machine cells in the presence of alternative routings for part types. The objective function is the minimization of transportation costs. Limits on cell… Expand
Assessing partnership savings in horizontal cooperation by planning linked deliveries
Cooperation through the supply chain has been seen as one of the most efficient ways of reducing costs and gaining competitiveness. Although many studies have considered vertical cooperation within a… Expand
