What is Dea Solver Pro?
Dea Solver Pro is a software package that enables you to perform DEA on your data sets using Microsoft Excel worksheets. It was developed by Kaoru Tone, a professor at the National Graduate Institute for Policy Studies in Tokyo, Japan, and is distributed by SAITECH Japan. It is based on the books Data Envelopment Analysis-A Comprehensive Text with Models, Applications, References and DEA-Solver Software, by W.W. Cooper, L.M. Seiford and K. Tone, and Advances in DEA Theory and Applications - With Extensions to Forecasting Models, edited by Kaoru Tone.
Definition and features of Dea Solver Pro
DEA is a non-parametric method that measures the relative efficiency of DMUs that use multiple inputs to produce multiple outputs. It does not require any assumptions about the functional form or distribution of the data, nor does it need any prior information about the weights or importance of the inputs and outputs. Instead, it uses linear programming techniques to construct an efficient frontier that envelops the observed data points, and then compares each DMU with the best-practice DMUs on the frontier.
Dea Solver Pro is a software that implements various DEA models and extensions to help you conduct DEA on your data sets. Some of the features of Dea Solver Pro are:
It can handle up to 50,000 DMUs, 1,000 inputs, and 1,000 outputs.
It can run over 100 DEA models, including basic models (CCR, BCC, SBM), additive models (ADD, FDH), network models (NDM), dynamic models (DEA-Dynamic), Malmquist productivity index models (MPI), cross-efficiency models (CE), super-efficiency models (SE), slacks-based measure models (SBM), directional distance function models (DDF), cost/revenue/profit models (CRP), undesirable output models (UO), weight-restricted models (WR), assurance region models (AR), cone ratio models (CR), multiplier bounds models (MB), returns-to-scale models (RTS), etc.
It can handle different types of data, such as continuous, discrete, ordinal, categorical, binary, etc.
It can handle different types of orientation, such as input-oriented, output-oriented, non-oriented, etc.
It can handle different types of returns to scale, such as constant returns to scale (CRS), variable returns to scale (VRS), non-increasing returns to scale (NIRS), non-decreasing returns to scale (NDRS), etc.
It can handle different types of efficiency, such as technical efficiency, allocative efficiency, scale efficiency, cost efficiency, revenue efficiency, profit efficiency, etc.
It can handle different types of DEA extensions, such as sensitivity analysis, bootstrap analysis, clustering analysis, ranking analysis, benchmarking analysis, forecasting analysis, etc.
It can handle different types of DEA objectives, such as maximizing efficiency, minimizing inefficiency, minimizing slacks, maximizing outputs, minimizing inputs, maximizing profits, minimizing costs, etc.
It can handle different types of DEA constraints, such as non-negativity constraints, weight constraints, ratio constraints, cone constraints, assurance region constraints, multiplier bounds constraints, etc.
It can handle different types of DEA outputs, such as efficiency scores, slacks/surpluses, weights/multipliers, shadow prices/dual variables, reference sets/peers, projections/targets, gaps/radials, etc.
It can generate various DEA reports and charts, such as summary reports, detailed reports, comparison reports, sensitivity reports, bootstrap reports, clustering reports, ranking reports, benchmarking reports, forecasting reports, etc.
It can export the DEA results to Excel worksheets or CSV files for further analysis or presentation.
