A powerful decision making is provided by Multi Criteria Decision Making (MCDM) in areas where choosing the optimal choice is difficult. This paper provides a comprehensive overview of the most prominent schools of thought about multi criterion decision making, both theoretically and practically. The primary goal is to catalog the available applications and methods,then recommend those that are the most reliable and efficient in finding the optimal solution. Decisions based on multiple criteria have found widespread use. When there are multiple criteria to consider, the optimal option can be selected utilizing a multi- criteria decision-making (MCDM) process, which takes into account each criterion's weight and range of applicability. In this review, we look at how MCDM has evolved and the several ways ithas been put to use.
