Ítem Acceso Abierto Joint chance-constrained reliability optimization with general form of distributions(CENTRUM Publishing, 2014) Vincent, Charles; Islam Ansari, Saifu; Khodabakhshi, MohammadProbabilistic or stochastic programming is a framework for modeling optimization problems that involve uncertainty. Stochastic programming models arise as reformulations or extensions of reliability optimization problems with random parameters. Moreover, the resource elements vary and it is reasonable to consider them as stochastic variables. In this paper, we describe the chance-constrained reliability stochastic optimization (CCRSO) problem for which the objective is to maximize the system reliability for the given joint chance constraints where only the resource variables are random in nature and which follow different general form of distributions. Few numerical examples are also presented to illustrate the applicability of the methodology.Ítem Acceso Abierto A Satisficing DEA Model to Measure the Customer-based Brand Equity(CENTRUM Publishing, 2015) Vincent, Charles; Zavala, JorgeEver since the inception of brand values, these have become a benchmark for many data-driven strategies, eventually providing a basis for vertical/horizontal integrations, as well. In recent decades, brands have become comparable across the industries, based on their value derived either from the customer perception or in terms of the firm financials. Numerous models have been developed in time to measure the customer-based brand equity; nevertheless, they all evaluate brand equity in an absolute sense. The present research paper provides an avenue to measure the customer-based brand equity in a relative sense using a satisficing DEA model. The information for this model has been collected through a customer-based survey questionnaire in line with predefined brand equity dimensions, which have been verified through a confirmatory factor analysis. We demonstrate the approach by means of applying the proposed model to measure the efficiency of cell phone brands.Ítem Acceso Abierto Measuring the Performance of a Dehydration Plant of Apples(CENTRUM Publishing, 2015) Sánchez Ramírez, Rodrigo Antonio; Vincent, Charles; González Araya, Marcela; Paliza, Juan CarlosGiven the importance of the Chilean dried-fruit market and the characteristics of the industrial process of dehydration, it becomes imperative for companies to measure the efficiency of their production processes in order to identify critical areas and take the necessary actions to improve them. Hence, the present work performs an efficiency analysis for the production of dried apples in a plant of the Maule region, Chile. The methodology used is Data Envelopment Analysis, considering both discretionary and non-discretionary variables. The results indicate that the application of the model without non-discretionary variables shows higher efficiency indices than the model with non-discretionary variables. Additionally, the efficiency analysis results, segregated by variety, origin, and fruit type, indicate that the selection of these segregations could be used to increase the production or generate higher efficiencies. Finally, the technological change in the same plant is analysed through the Malmquist index. The findings of this research could help improve the decision-making process of managers concerned with the efficient use of resources within the company.Ítem Acceso Abierto A translation invariant pure DEA model(CENTRUM Publishing, 2015) Vincent, Charles; Färe, Rolf; Grosskopf, ShawnaThis short communication complements the DEA model proposed by Lovell and Pastor (Eur. J. Oper. Res. 118 (1999), 46-51), by incorporating both positive and negative criteria in the model. As such, we propose a DEA model, known as pure DEA, using a directional distance function approach.Ítem Acceso Abierto The Right To Be Forgotten – Is Privacy Sold Out in the Big Data Age?(CENTRUM Publishing, 2014) Vincent, Charles; Tavana, Madjid; Iona Gherman,TatianaThe potential of big data has exceeded the expectations of most organizations. However, despite its vast importance and application, some important aspects of big data remain the subject of debate. One of the most sensitive and worrisome issues for big data is the privacy of personal information. The purpose of this paper is to explore how the major theories of philosophical ethics may be used as a referential framework for conceptualizing the evolution of the concept of privacy of personal information in the big data era. We identify a gap in big data research and suggest that while privacy has been extensively explored in different settings, it has not been sufficiently studied relative to the social and technological changes in the big data era. We attempt to fill this gap by proposing that the study of privacy be closely tied to the evolution of the social structure.
