Celebrating the 45th Anniversary of DEA,

Dear Colleagues,

We have the great pleasure of inviting you to participate in the DEA45: International Conference on Data Envelopment Analysis to be held September 4-6, 2023 at Surrey Business School, University of Surrey, Guildford, UK. The University of Surrey is located on a landscaped campus on the outskirts of Guildford. London is only 35 minutes away by train and its major airports of Heathrow and Gatwick are both within easy reach, giving ready access from all over the world. Please see call for papers at  

DEA: 45 years on
In the seminal paper, Charnes, Cooper, and Rhodes (European Journal of Operational Research 2, 429-444, 1978) introduced DEA as a linear programming based method for measuring the comparative efficiency of decision making units (DMUs). Since then DEA has seen exponential growth in both theoretical development and applications. Thousands of papers have been published extending the methodology to address numerous aspects of real life problems. Applications though lagging behind theory are nevertheless well established, ranging from the regulation of utilities to the delivery of financial, health, education and other public and private sector services. Following the DEA40 conference at Aston University in 2018, which celebrated the 40th anniversary of the seminal paper on DEA,  we are now organizing the DEA45 conference in 2023 on the 45th Anniversary of that, the most frequently cited paper in Operational Research journals.

Outline of the Conference
The conference will feature: Papers on the latest research in the field;Applications focused tracks including on Regulation, Agriculture, Education, Financial and Health Services;Round table discussions aimed at early career researchers where former or  current Editors of Journals in the field, including the European Journal of Operational Research and the Journal of Productivity Analysis will offer advice on getting published;

Conference program:
September 4, 2023: Opening Ceremony + Full Day Conference + Welcome Reception
September 5, 2023: Full Day Conference + Gala Dinner
September 6, 2023: Half Day Conference + Closing Ceremony Submissions: More information about the scientific and social program of the conference as well as paper submission can be found at

Call for papers: Environmental Science and Policy; Special issue on “DEA-based index systems for addressing the United Nations’ SDGs”

The global Sustainable Development Goals (SDGs) were established by the United Nations General Assembly in 2015, as extensions of the UN Millennium Development Goals. These SDGs contain 17 goals and 169 targets aimed at “ending poverty, protecting the planet, and ensuring prosperity for all” (UN, 2018). Governments, private companies, organisations, and civil societies have been challenged to work together until 2030 to accelerate the progress towards achieving sustainable development.

Special issue information:

Achieving sustainable development is, therefore, a massive, complex, and ongoing task and one of the first steps in the assessment of whether goals can be met by 2030 involves the development of methods and tools to monitor the SDGs’ progress (Cristóbal et al., 2021; Nhamo et al., 2020). However, quantifying the level of sustainability attained by a system (be it a nation, region, sector, or business) is a challenging task due to the need to consider a wide range of economic, environmental, and social aspects simultaneously (Galán-Martín et al., 2016).

Data Envelopment Analysis (DEA) has been shown to be a well-established promising tool for such purposes, especially because it considers each sustainability dimension separately and can handle a large number of indicators. DEA is an optimisation-based management science technique for identifying the best practices of a group of decision-making units (DMUs) whose performance is categorised by multiple performance metrics that are classified as inputs and outputs. The construction of composite indicators, in particular, is a stream of research in the DEA literature for assessing sustainable development that has been gaining traction in recent times (Zakari et al., 2022). This is because indices are easy to communicate and can measure multi-dimensional concepts that may not share common units of measurement.

Studies aimed at examining sustainability using DEA have started to emerge (Chuai et al., 2021; Xu & Yao, 2022), although they are still scarce. However, when it comes to building (composite) indices using DEA, most of the existing studies have only looked at a specific dimension of the SDGs, for example, food supply/SDG2 (Lucas et al., 2021), health/SDG3 (Habib & Shahwan, 2020), energy/SDG7 (Zakari et al., 2022), or CO2 emissions/SDG13 (De Castro Camioto et al., 2014).

Therefore, the topic of this Special Issue is very timely, and it is expected that contributed articles will be of interest to a wide audience, from academics to practitioners, NGOs, and governmental bodies. It is expected that the research papers will assist relevant decision and policymakers in their attempt to measure sustainability and design policies aimed at raising the level of efficiency of current SDG policies, identifying and engaging in best practices, and allocating governmental resources – ultimately, with the overarching aim of achieving sustainable development.

This Special Issue welcomes original research articles of high quality that focus on building robust DEA-based index systems to measure and benchmark the SDGs across a variety of empirical contexts. The papers can use different theoretical lenses in the way they approach the conceptualisation and measurement of sustainability. For example, the papers can build upon literature on institutional theory, participation and community development, and global value chains, among others. Theoretical, conceptual, methodological, and empirical research studies are encouraged. The development of new or enhanced solutions are of considerable interest. Contributions from both the academic and the practitioner communities are supported.

Call for papers: OR Spectrum; Special issue on “Advancements in Stochastic DEA and Environmental Efficiency Applications”

Guest editors:

Submission deadline: July 31, 2022

The twenty-first century demands an urgent balance of economic and social development, as well as environmental protection and stewardship. Higher energy consumption is required to support the continued growth of the human population and rising living standards. However, this primarily leads to increased pollution and waste from industrial, agricultural, and construction activities alike, to name a few. Moreover, the public‘s attention is increasingly focused on addressing environmental problems caused by pollution, such as GHG emissions, which in turn has increased the focus on environmental efficiency evaluation in recent years.

Stochastic Data Envelopment Analysis (SDEA) can assist in determining how to achieve this balance. Data envelopment analysis (DEA) is a popular tool for analysing and measuring efficiency in both the public and private sectors. DEA considers multiple-input and multiple-output situations and compares the relative efficiency of factor input and output of multiple similar entities, also known as decision-making units (DMUs). In its original configuration, DEA is a non-stochastic tool that assumes all input and output data are quantitative, with specified numerical values; in other words, they are both deterministic and noise-free. In real-world applications, however, inputs and outputs are frequently of a stochastic nature, fluctuating over time, making it difficult to establish precise numbers for them based on the limited historical data. The introduction of SDEA, in which the possibility of noise in the data and the consideration of measurement errors and specification errors are explicitly taken into account, has been found to be efficient in dealing with and measuring the uncertainties in one or more DMUs.

The purpose of an SDEA approach under these circumstances is straightforward. Achieving environmental sustainability is fraught with uncertainty, which can manifest itself in a variety of ways, including process activities, resource consumption, and emissions across the value chain, among other things. The outstanding feature of most existing studies dealing with environmental efficiency analysis is that they model variables such as wasting water, GHG emissions, the production of useless solid materials, etc. as deterministic variables. As mentioned, DEA models with stochastic settings have been developed to accommodate both inefficiency and the presence of noise, measurement errors, and specification errors. But then again, despite substantial progress with SDEA approaches, research focusing on the use of SDEA to address environmental efficiency across domains is rather scarce.

Against this background, this Special Issue aims to compile original research articles of high quality that focus on recent advancements in SDEA and environmental efficiency applications. Theoretical, conceptual, methodological, and empirical research studies are all of interest. Contributions from both the academic and the practitioner communities are encouraged. In order to not only bring together the most recent knowledge but also to close the gap between scientific research and practical impact, we especially encourage contributions that are implementation-focused, i.e., with real-world data experiments, pilots, and industry collaborations.

Specific topics/applications of interest include, but are not limited to:

  • Environmental efficiency of countries and regions
  • Environmental efficiency of energy and carbon dioxide emissions  
  • Environmental efficiency of regional or national energy production
  • Environmental efficiency in the context of the green economy or circular economy and the sustainability of supply chains
  • Environmental efficiency of manufacturing firms
  • Environmental efficiency of construction companies
  • Environmental efficiency of maritime companies
  • Environmental efficiency of container ports
  • Environmental efficiency of (electric) fossil fuels
  • Environmental efficiency of oil and gas companies
  • Environmental efficiency of chemical and pharmaceutical companies
  • Environmental efficiency of regional or national transportation systems
  • Environmental efficiency in agriculture (at farm-level, crop-level, etc.)
  • Environmental efficiency in aviation

Specific methods of interest include, but are not limited to:

  • Stochastic DEA (with a consideration of stochastic inputs and outputs, desirable and undesirable stochastic inputs and outputs, etc.)
  • Stochastic cross-efficiency DEA
  • Stochastic network DEA
  • Chance-constrained DEA
  • Satisficing DEA
  • Stochastic frontier analysis
  • Stochastic programming
  • StoNED DEA
  • State-contingent approaches

Call for Exclusive Book Chapters: Decision Making Optimization Models for Business Partnerships: Data Envelopment Analysis and Parametric Approaches”


Gholam R. Amin and Mustapha Ibn Boamah, Faculty of Business, University of New Brunswick, Saint John, Canada

Submission deadline: 30 April 2023

Decision making optimization models for business partnerships are essential, as businesses seldom have all of the resources they need, and thus they require alliances and partnerships with others to enable them to meet their goals. A book on optimal business partnership models, with foundations in management science and economic theory, would therefore be an important resource in understanding and quantifying business partnership gains. Many studies emphasize the importance of business partnerships. However, literature on partnership optimization is quite limited. The proposed new book will cover recent developments in decision making as it relates to business partnerships using data envelopment analysis (DEA), inverse DEA, and other decision-making methods, including parametric approaches. As introduced in Charnes et al. (1978), DEA can be safely viewed as one of the success stories of operations research and management science for evaluating relative efficiency of decision-making units (DMUs) in the presence of multiple inputs and multiple outputs. Research in recent years and outputs required for business partnerships to achieve given efficiency targets.
The objective of this edited book is to develop new DEA and other decision-making optimization models to answer key questions related to business partnerships that would be of interest to business firms, policy makers, and practitioners in areas such as firms’ restructuring, resource allocation, environment and climate change, pollution minimization, and gain maximization from mergers and acquisitions. The book:

  1. will introduce DEA models to estimate the potential gains from mergers and acquisitions for various DMUs and guide them on how to combine their resources to get the maximum benefits out of the resulting synergies.
  2. will introduce advances in DEA optimization and other techniques through the development of models that will define various types of business partnerships between DMUs.
  3. will develop the literature of business partnerships that would guide partners on how redistributing their resources could improve their efficiency score.
  4. will help partners to use each other’s resources in order to reach target efficiency.
  5. will extend the well-known non-parametric performance measurement approach of DEA that would help business firms to collaborate and improve their efficiency.
  6. will guide business firms on how to choose partners to reduce negative externalities such as environmental pollution.
    Submissions may be sent directly to the editors at (Gholam R. Amin) or (Mustapha Ibn Boamah).
