Ordinal Priority Approach (OPA) is a new Multiple Criteria Decision-Making (MCDM) method that can determine the weights of experts, criteria and alternatives after a few steps. This method employs ordinal data as input data which is simple and easy to collect. The core model is established based on Linear Programming (LP) approach. Moreover, handles Group Decision Making (GDM) problems and incomplete information to facilitate the decision-making process. The OPA Software can be found on the website for free: https://ordinalpriorityapproach.com
