Fuzzy Linear Programming in Practice: An Application to the Spanish Football League
2010
FLP problems are perhaps one of the most and best studied topics of Soft Computing, and are among the most fruitful in applications and in theoretical and practical results. Areas of application of FLP problems are many and varied and in fact suppose an extraordinary example of technology transfer in action. In this paper, Fuzzy Linear Programming models are applied to the European football game in which the inherent uncertainty of the parameters relating to the football teams in the Spanish Football League serve to establish these models and so optimize the returns of the investments made to maintain a high quality competition. In this context, fuzzy DEA models are established which provid…
Innovation efficiency: a bibliometric review and future research agenda
2021
Innovation efficiency has become a phenomenon of global interest. This paper reviews 165 articles from academic journals of innovation efficiency, applies the data-driven text mining approach to ma...
Sustainability and supply chain infrastructure development
2012
PurposeThis study aims to examine logistics infrastructure, trade differences, and environmental and social equity factors, for a set of 89 countries.Design/methodology/approachFollowing recent work which uses secondary data sources for supply chain research at the country‐level, data were obtained from the World Bank and International Monetary Fund databases. Data envelopment analysis (DEA) was used to compute country‐level efficiencies and ANOVA was used to do regional comparisons.FindingsThe analysis shed light on country‐level dimensions of logistics infrastructure and trade performance. It also provided insights regarding environmental (e.g. CO2 emissions) and social equity (e.g. healt…
Composite Indicator of Social Inclusion for the EU Countries
2016
Social inclusion is one of the key challenges of the European Union Sustainable Development Strategy (EU SDS). We use the main indicators identified by Eurostat within the operational objectives of the specific European policies to measure social inclusion for the 27 member countries of the European Union. In particular, we aggregate four basic indicators in a multiplicative composite indicator via a DEA-BoD approach with weights determined endogenously with proportion constraints. We obtain a score of social inclusion that allows us to grade the 27 EU countries from 2006 to 2010. In this way, we highlight the specific role played by the four indicators in determining improvements and deter…
Ranking world tourist destinations with a composite indicator of competitiveness: To weigh or not to weigh?
2019
Abstract This paper contributes a weighted composite indicator of competitiveness for 136 world tourist destinations. To that end, Data Envelopment Analysis and Multi-Criteria-Decision-Making techniques are used with raw indicators from the 2017 edition of the Travel & Tourism Competitiveness Report of the World Economic Forum (WEF). An outstanding feature of our approach is that weights are endogenously generated. Furthermore, the role played by several variables in tourism competitiveness is assessed using truncated regression and bootstrapping. The ranking of world tourist destinations produced by our weighted composite indicator of competitiveness is, however, fairly similar to that der…
Evaluating the Efficiency of Water Distribution Network Sectors Using the DEA-Weight Russell Directional Distance Model: The Case of the City of Vale…
2021
In many cities, sectorization projects of the drinking water distribution network have been implemented. This study provides a methodology to evaluate the efficiency of the sectors of a water distribution network by applying a data envelopment analysis weighted Russell directional distance (DEA-WRDD) model. This non-radial DEA model gives the overall efficiency of each unit of analysis, as well as each input, output, and undesirable output considered in the evaluation. The variables used in the analysis provide a multidisciplinary view: economic factors (covering costs), water quality parameters, and technical aspects. The empirical analysis was performed for the sectors of the water distri…
Assessing the efficiency of Chilean water and sewerage companies accounting for uncertainty
2016
Abstract Efficiency assessment of water and sewerage companies (WaSCs) has attracted considerable attention both for water company managers and water regulators. Within the methodological approaches that can be applied to estimate efficiency scores, data envelopment analysis (DEA) is the most widely applied technique. In spite of the positive features of DEA, it presents a major drawback which is its deterministic nature. In other words, conventional DEA models do not account for uncertainty in the data. To overcome this limitation, we assess, for the first time, the efficiency of a sample of Chilean WaSCs by using a DEA model with statistical tolerance in the data. Hence, 81 efficiency sco…
Eco-efficiency assessment of olive farms in Andalusia
2012
Abstract Olive farming represents an important source of income and employment in the rural areas of Andalusia (Spain), which is the most important olive oil-producing region in the world. Unfortunately, it also exerts significant environmental pressures with regard to soil erosion, use of polluting inputs, excessive water consumption and biodiversity reduction. This paper uses Data Envelopment Analysis (DEA) techniques and pressure distance functions to contribute a farm-level assessment of the eco-efficiency of a sample of 292 Andalusian olive farmers. We distinguish between managerial eco-efficiency and program eco-efficiency, the latter being associated to the different natural conditio…
Assessing performance in the management of the urban water cycle
2011
This paper proposes the use of directional distance functions and Data Envelopment Analysis techniques to assess technical efficiency in the provision of the different stages of the urban water cycle in Andalusia, a Southern European region. Evaluating performance in the management of specific stages of the urban water cycle provides utility managers and regulating authorities with relevant information that may not be detected by more conventional approaches based on assessing performance at utility level. We find that Andalusian water and sewage utilities could achieve significant increases in the volume of water delivered without diminishing the output of their other services and using th…
Assessing environmental performance in the European Union: Eco-innovation versus catching-up
2017
Abstract This paper assesses environmental performance in the European Union (EU) using Luenberger productivity indicators, directional distance functions and Data Envelopment Analysis techniques. It considers four indicators of the pressures exerted by economic activity on the environment: global warming, tropospheric ozone formation, acidification and particulate formation. The change in environmental performance from the early 2000s onwards is decomposed at the levels of country and environmental pressure, and as the result of eco-innovations and catching-up with the best available environmental technologies; furthermore, we distinguish between the periods of economic growth (2001–07) an…
