What problems does dea model apply to solve?

Is it applicable to the comprehensive evaluation of the effectiveness of multi-output and multi-input?

Data Envelopment Analysis (DEA) was proposed by Charnes, Coopor and Rhodes in 1978. The principle of this method is to keep the input or output of the decision-making unit unchanged.

Common uses of DEA model

DEA method and its model have been widely used in different industries and departments since they were put forward by famous American logistics scientists A.Charnes and W.W.Cooper in 1978, and have shown unique advantages in dealing with multi-index input and multi-index output. Using DEA to measure efficiency can clearly explain the combination of input and output, which is more comprehensive and credible than a set of operating ratio or profit indicators. It is a new cross-research field of operational research, management science and mathematical economics.

Why did you choose to use the billion-picture DEA template?

1. There are many import formats.

Billion maps can be imported into other formats, such as Visio and SVG formats, and can also be converted into Edraw files in batches, which is more convenient to operate.

2. Export multiple formats

Support the export of word, Excel, PPT, pdf, svg, png and other formats.

3. Easy to share

After the drawing is completed, you can share your class diagram works to mainstream social platforms such as WeChat, friends circle and Weibo with one click to facilitate communication with others.

4. Support multiple systems

Support windows system, MAC system and Linux system with strong adaptability.

5. Simple operation and easy use

Drag-and-drop operation, the software can also perform automatic alignment and adsorption.

6. Massive templates, super high value

There are 260 drawing types, more than 26,000 vector graphics and more than 3,000 drawing templates. Even beginners of zero-based drawing can operate easily.
