Data Envelopment Analysis (DEA) Tutorial17

Data envelopment analysis (DEA) is a non-parametric technique that is used to evaluate the relative efficiency of a set of decision-making units (DMUs). DMUs can be anything from businesses to hospitals to schools. DEA is based on the idea that the efficiency of a DMU can be determined by comparing its inputs and outputs to those of other similar DMUs.

The first step in conducting a DEA analysis is to identify the inputs and outputs that will be used to measure the efficiency of the DMUs. Inputs are the resources that are used by the DMUs to produce their outputs. Outputs are the products or services that are produced by the DMUs.

Once the inputs and outputs have been identified, the next step is to collect data on the DMUs. This data can be collected from a variety of sources, such as financial statements, operational data, and customer surveys.

Once the data has been collected, the next step is to construct a DEA model. The DEA model is a mathematical model that is used to calculate the efficiency of the DMUs. There are a variety of different DEA models available, and the choice of model will depend on the specific application.

Once the DEA model has been constructed, the next step is to solve the model. The solution to the DEA model will provide a measure of the efficiency of each DMU. The efficiency measure is a number between 0 and 1, where 1 indicates that the DMU is efficient and 0 indicates that the DMU is inefficient.

The results of a DEA analysis can be used to identify the most efficient DMUs and to improve the efficiency of the least efficient DMUs. DEA can also be used to identify the strengths and weaknesses of different DMUs and to make informed decisions about how to allocate resources.

How to Conduct a DEA Analysis

To conduct a DEA analysis, you will need to follow these steps:1. Identify the DMUs that you will be evaluating.
2. Identify the inputs and outputs that will be used to measure the efficiency of the DMUs.
3. Collect data on the DMUs.
4. Construct a DEA model.
5. Solve the DEA model.
6. Analyze the results of the DEA analysis.

DEA Software

There are a number of different software programs that can be used to conduct DEA analyses. Some of the most popular DEA software programs include:* DEA Solver
* GAMS
* MATLAB
* R

DEA Resources

There are a number of resources available to help you learn more about DEA. Some of the most helpful resources include:* The DEA Society website
* The DEA Tutorial website
* The DEA Book website

Conclusion

DEA is a powerful tool that can be used to evaluate the relative efficiency of a set of DMUs. DEA can be used to identify the most efficient DMUs and to improve the efficiency of the least efficient DMUs. DEA can also be used to identify the strengths and weaknesses of different DMUs and to make informed decisions about how to allocate resources.
