Review on AHP and TOPSIS
The aim of this work is to critically analyse the principles and application of the Analytic Hierarchy Process (henceforth, AHP) and the Technique for Order of Preference by Similarity to Ideal Solution (henceforth, TOPSIS) in the sense that whether the chosen alternatives and criteria allow the users to determine that the option provides a better solution and helpful leading to an effective decision.
The AHP and TOPSIS seem to be powerful tools given the fact that the set of scores are obtained by the evaluation of each criterion and options within each upon the decision-makers’ experience. Given the inevitability of increase in complexity of data, the decision making, especially strategic decision making, might likely overload the decision maker. There seems to appear a certain need for swift response in line with an analysis of the whole situation which has to be assessed with proper judgment and experience despite the impact of the limitation of alternatives, therefore choice.
With the combination of a quantitative data gathered along with the involvement of multiple respondents, decisions are available to be made collectively. The single-criterion or multiple-criterion decision making requirement has also an influence upon the outcome as the nature of decision-making involves choice.
