Theoretical Aspects of Multi-criteria Decision-Making (MCDM) Methods

Abstract

Multi-criteria decision making is recorded as one among many thriving disciplines associate to settling thoughts and issues in relation to the multiple features of the alternatives. Decision is made in daily bases which is part of life. However, it could be associated to a particular person’s interest. In other words, decision is made during an intention to either do something or not. These decisions can be considered on intent on what to eat, wear or purchase or a career to choose as the case may be. However, this research centers on making a choice on having a specific character of interest. Many decision making issues have real contradictory objectives in life that are highly considered. Multi-criteria decision-making is considered among many fields that allow selection to take place. Material selection is one of the biggest features to consider in engineering and research. Furthermore, selecting a material to be used in a research or in decision-making area is a distinctive building technique that is important in solving selection problems. Technically, choosing a material or in other times replacing existing material may be as a result of in effectiveness of the first which can easily be replaced by the later. Multi-criteria decision making in other terms can be a qualitative and quantitative analysis. It is applicable incredibly in different areas (fields) of specialization. This work introduces multi-criteria decision making approaches in solving and analyzing the problem that tilts towards solving environmental engineering problems, understanding its strengths and weaknesses involved.
