A Solution Concept Related to “Bounded Rationality” for some Two-Echelon Models, International Game Theory Review Vol. 21, No. 1 (2019), 1-22

[:es] Joaquin Sanchez-Soriano (University Miguel Hernández of Elch) and Natividad Llorca (University Miguel Hernández of Elche)
Abstract.  Two-echelon models describe situations in which there are two differentiated groups of agents. Some examples of these models can be found in supply chain problems, transportation problems or two-sided markets. In this paper, we deal with two-sided transportation problems which can […]

The curse of dimensionality of decision-making units: A simple approach to increase the discriminatory power of data envelopment analysis, European Journal of Operational Research 279 (2019), 929–940

[:es] Vincent Charles (University of Buckingham) , Juan Aparicio (University Miguel Hernández of Elche) and Joe Zhu (UWorcester Polytechnic Institute)
Abstract.  Data envelopment analysis (DEA) is a technique for identifying the best practices of a given set of decision-making units (DMUs) whose performance is categorized by multiple performance metrics that are classified as inputs and outputs. Although DEA […]

Existence of periodic solutions for a scalar differential equation modelling optical conveyor belts, Journal of Mathematical Analysis and Applications (2019), 480, 1-20

[:es]Luis Carretero (University Miguel Hernández of Elche) and José Valero (University Miguel Hernández of Elche).
Abstract.  We study a one-dimensional ordinary differential equation modelling optical conveyor belts, showing in particular cases of physical interest that periodic solutions exist. Moreover, under rather general assumptions it is proved that the set of periodic solutions is bounded.
Keywords. Ordinary differential equations; Periodic solutions; […]

Defining a new graph inefficiency measure for the proportional directional distance function and introducing a new Malmquist productivity index, European Journal of Operational Research (2019) 281, 222-230

[:es]Juan Aparicio (University Miguel Hernández of Elche), Jesús T. Pastor (University Miguel Hernández of Elche) and C. A. Knox Lovell (University of Queensland,).
Abstract. A natural multiplicative efficiency measure for the Constant Returns to Scale proportional directional distance function (pDDF) is derived, relating its associated linear program to that of the well-known outputoriented radial efficiency measurement model. Based on […]
