DEA-based performance measurement with a centralized view on DMUs
Final Report Abstract
Standard Data Envelopment Analysis (DEA) has widely been used to evaluate the efficiency of Decision Making Units (DMUs) on the assumption that each DMU operates independently. Under the scenario of a centralized management, however, an umbrella organization strives for improving the overall performance of its DMUs. Our research addresses this scenario by modifying DEA-based benchmarking systems according to a controlling-type structure by which the central management’s preferences can be taken into account. In particular, the DFG project served to develop approaches to incorporate crucial controlling parameters into DEA with a centralized view of measurement. The purpose of the second part of the project was to bridge the gaps between the research area of the centralized view of measurement and the domain of frontier-based incentive regulation. Our studies on different aspects of this relationship has helped us produce high-quality research. Our respective findings opened up one more research avenue addressed in a further project. This has addressed the incorporation of environmental variables into the centralized view of measurement. The methods which have been applied can be subsumed under the umbrella of performance analytics, location analytics, incentive regulation and operations research. In order to achieve the objectives, research has been concentrated on developing mathematical programming models such as linear and integer programming models as well as techniques in statistics and data mining. In order to illustrate the applicability of the proposed frameworks and the corresponding mathematical models, extensive numerical experiments and simulations have also been carried out. In particular, in order to exemplify the type of real-world problems that can be addressed by our proposed models, different data sets have been generated based on the information from: maintenance units of KONE corporation, electricity transmission service operators in Brazil, German savings banks, and hospitals in the district of Braunschweig.
