“…The model can also be expressed in terms of output, that is to say, to maintain the maximization objective of the same number of outputs, keeping the number of inputs constant. Recent investigations such as that of (Aparicio et al, 2016), explore the inefficiency measurement in models that allow changing the supplies and the products at the same time.…”

This investigation seeks to determine the relationship between working capital as a financial measure and the efficiency level of construction companies. The study sample is intentional, with 58 participating companies, from which the financial information was obtained in a time horizon of four years (2011-2014). In the first stage efficiency was assessed using Data Envelopment Analysis (DEA), and in the second stage Tobit regression model was applied in order to identify the relationship between the variables. Efficiency levels evaluated show a reduction in the average efficiency in the construction sector for the years 2012 and 2013, and the regression results do highlight a positive link between efficiency and working capital for all years, which indicates that a common financial strategy based on reducing working capital does not lead to an increase in the efficiency level of construction firms. This research can benefit not only Ecuadorian construction companies, but others who wish to improve their competitive advantage based on their financial information.

“…That is the case, for example, of those DEA approaches that search for the least distant target (e.g. Aparicio et al 2007, 2017, Aparicio 2016 or compute a stepwise benchmarking path that divides the total improvement effort so that it does not have to be made all in one step (e.g. Lozano and Villa 2005, Lozano and Calzada-Infante 2018.…”

In this paper, a new interactive multiobjective target setting approach based on lexicographic directional distance function (DDF) method is proposed. Lexicographic DDF computes efficient targets along a specified directional vector. The interactive multiobjective optimization approach consists in several iteration cycles in each of which the Decision Making Unit (DMU) is presented a fixed number of efficient targets computed corresponding to different directional vectors. If the DMU finds one of them promising, the directional vectors tried in the next iteration are generated close to the promising one, thus focusing the exploration of the efficient frontier on the promising area. In any iteration the DMU may choose to finish the exploration of the current region and restart the process to probe a new region. The interactive process ends when the DMU finds its most preferred solution (MPS).

“…In the same year, Gonzalez and Alvarez (2001) introduced the concept of input-specific contractions and found a relevant benchmark for inefficient units by minimizing this contraction in the inputs required to reach the efficient subset. Nevertheless, it does not guarantee to reach the strong efficient frontier and more recently Aparicio et al (2017a) developed an approach based on bi-level linear programming by means of special ordered set (SOS) for setting the closest targets.…”

A modified distance friction minimization approach in data envelopment analysis

et al. 2019

View full text Add to dashboard Cite

A multi-step distance friction minimization (DFM) approach has been developed to assist a decision making unit to improve its efficiency. This approach contracts inputs and expands outputs simultaneously through the minimization of distance friction relative to the strongly efficient frontier based on a weighted Euclidean norm. In this paper, we point out that the DFM approach has a problem by means of two numerical examples and then show how to solve the problem. Using a real data set, we not only confirm the occurrence of this problem inherent in the original formulation, but also demonstrate how our modification works.
