“…In many real applications, DMUs may contain several production processes before achieving final outputs (Kao and Hwang, 2008;Zha and Liang, 2010;Zhou et al, 2013;Liu and Lu, 2012;Halkos et al, 2014;Aviles-Sacoto et al, 2015). Recently, Lozano and Villa (2010) estimated the potential merger gains of two DMUs with parallel structures and found that a hypothetical DMU combined by two DMUs could potentially have cost savings.…”

This paper develops a novel two-stage cost efficiency model to estimate and decompose the potential gains from Mergers and Acquisitions (M&As). In this model, a hypothetical DMU is defined as a combination of two or more candidate DMUs. The hypothetical DMU would surpass the traditional Production Possibility Set (PPS). In order to solve the problem, a Merger Production Possibility Set (PPS M ) is constructed. The model minimizes the total cost of the hypothetical DMU while maintaining its outputs at the current level, and estimates the overall merger efficiency by comparing its minimal total cost with its actual cost. Moreover, the overall merger efficiency could be decomposed into technical efficiency, harmony efficiency, and scale efficiency. We show that the model can be extended to a two-stage structure and these efficiencies can be decomposed to both sub-systems. To show the usefulness of the proposed approach, we applied it to a real dataset of top 20 most competitive Chinese City Commercial Banks (CCBs). We concluded that (1) there exist considerably potential gains for the proposed merged banks. (2) It is also shown that the main impact on potential merger gains are from technical and harmony efficiency. (3) As an interesting result we found that the scale effect works against the merger, indicating that it is not favorable for a full-scale merger.

“…Al principio solo se agregó un 50% de harina de polen, pero se observó que el pan tenía un sabor amargo, una mala consistencia de la masa, así como una textura dura después de hornear por lo que se fueron realizando modificaciones para mejorar el sabor, aspecto y textura. Las variables con la que se experimentó son; Harina de trigo (93-95g), Harina de polen (5-10g), jarabe de miel (10-14ml) con agua (30-37ml), así como tiempo de horneo, tiempo de fermentación en la primera y segunda acción, hasta ajustar la formulación adecuada sensorialmente para la torta estableciendo dichos parámetros para la formulación de mezclas por el método de multivariables de Zhu (AVILÉS-SACOTO et al, IMANIRAD et al, 2015;FLECHA, 2015;MARTINEZ et al, 2017;SALA;HAROS, 2016).…”

Todos los días invariablemente un alimento de consumo popular en la mesa semanal y a cualquier hora del día es el pan, actualmente para sectores de la población la modificación en sabores, texturas y composición poseen auge en el comercio. La sustitución de la harina de trigo por diferentes cereales, leguminosas o ingredientes funcionales abarcan espacio en panadería tradicional como en las panaderías del centro comercial. El polen de abeja es un alimento saludable ya que posee 30-35 % de proteína en forma de aminoácidos esenciales por arriba del patrón. Sus capas de ectina y exina permiten al polen no ser tan digerible al ser humano, por lo que un producto horneado favorecería su aprovechamiento. En esta investigación se va a establecer la formulación adecuada para integrar la harina de polen a un pan blanco de masa salada hasta donde sensorialmente no se detecte la adición, así como estandarizar la metodología de panificación. Tomando en cuenta parámetros como: Cantidad de harina de trigo-polen y azúcar, tiempo de fermentación, tiempo de horneo y temperatura de horneo. El producto obtenido es valorado sensorialmente para determinar la concentración de harina y cuál es el porcentaje de adición mejor evaluado sensorialmente, el rango de adición aceptado es de 5 a 10 % de sustitución de harina de trigo. Sensorialmente no existe diferencia en atributos como color, olor, sabor, consistencia y textura en este rango, siendo ligeramente mejor el sabor a 10% de Harina de polen. No obstante el pan blanco obtenido se puede comercializar hasta 10% de adición, siendo alternativa de los apicultores para obtener ganancias extras no solo de la venta de miel.

“…For recent developments on modeling network DMUs using DEA refer to Cook and Zhu [31]. In a recent study, Aviles-Sacoto et al [32] Premachandra et al [16] conceptualize mutual fund management process as a two-stage process comprising of an operational management process followed by a portfolio management process and consider overall efficiency as a weighted average of individual stage based efficiencies. Conceptualizing operational management (stage 1 process) as securing funds through advertising and management remuneration, Premachandra et al [16] use marketing and distribution fees and management fees as stage 1 inputs and net asset value as the stage 1 output which in turn is used as an input at stage 2.…”
