Data envelopment analysis

The software makes a data envelopment analysis (DEA) and an alternative DEA to redistribute the loads between variables. Futhermore, using the loads of the variables, it makes an hierarchical analysis to select the most outstanding variables.

For each action you select, complete the values and click the "Go" button.

Steps:

1. As first step load an example, load a data set or build a new one.
2. Select "Model" tab.
3. Now, if you want, you can change the orientation of the model.
4. Now add inputs and outputs to the model. You must select at least one input and one output.
5. Select the tab with the results you want to show.

You can enter new values and the results will be updated automatically.

The tabs "Hierarchical Model" and "Parametric Model" requires at least one more input or output.
