## Multiple-Criteria Decision Analysis

Multiple-Criteria Decision Analysis (MCDA) is a common problem in real-life situations. This problem has three important elements, including experts, criteria, and alternatives. When there is a need to make a decision, the Multiple-Criteria Decision Analysis methods can help us. For example, when we want to decide which car is suitable to buy, it is a decision-making problem that can be solved using Multiple-Criteria Decision Analysis methods. For buying a car, criteria can be price, quality, comfort, etc. The available cars can be defined as alternatives. One of the most recent Multiple-Criteria Decision Analysis methods is the Ordinal Priority Approach. It can consider the three important elements of decision problem simultaneously which makes it different from other existing methods. There are several software which can solve the Multiple-Criteria Decision Analysis problems using the Ordinal Priority Approach at the speed of light.

## Web-Based Software for Multiple-Criteria Decision Analysis Problems

To facilitate the process of solving Multiple-Criteria Decision Analysis Problems using the Ordinal Priority Approach, a web-based solver is provided. This software has no limitations regarding the number of experts, criteria, and alternatives. It is easy to use and freely available for scholars who want to use the Ordinal Priority Approach in Multiple-Criteria Decision Analysis Problems. The following Figure shows the Web-Based Software for Multiple-Criteria Decision Analysis Problems.

## Excel-Based Software for Multiple-Criteria Decision Analysis Problems

To solve Multiple-Criteria Decision Analysis Problems using the Ordinal Priority Approach, there are Excel-based, Web-based software, and MATLAB-based solver. The Excel-based software is useful for small-size problems of Multiple-Criteria Decision Analysis because the Solver of the Excel is limited and cannot handle a lot of constraints. The Excel-based solver is very easy to use and fast. It can solve the Multiple-Criteria Decision Analysis problems at the speed of light.

## MATLAB-Based Software for Multiple-Criteria Decision Analysis Problems

To solve Multiple-Criteria Decision Analysis Problems using the Ordinal Priority Approach, there are Excel-based, Web-based software, and MATLAB-based software. The MATLAB-based software is useful for large-scale problems of Multiple-Criteria Decision Analysis. The MATLAB-based solver has user manual file, which can facilitate the process of solving the problem.
