The hierarchy usually includes a main goal, criteria, and alternatives, from the top to the bottom.
The frame work has three levels comprising the goal, criteria and errors (alternatives).
The goal, criteria, subcriteria (if any), and alternatives can be determined through literature reviews and collective discussions.
It structures the rational analysis of decision making by dividing a problem into hierarchies including goal, criteria, subcriteria (if any), and decision alternatives.
AHP structures a decision problem into a hierarchy with a goal, criteria and alternatives, while the ANP structures it as a network.
Formulation of the aim of the work and hierarchy construction: Decomposition of decision problem into individual items, taking into account their common characteristics, and formation of the appropriate hierarchical model with different levels (at least three: goal, criteria and alternatives).
The Analytic Hierarchical Process (AHP) approach is a common, very popular and widely used Multi-Criteria Decision Making (MCDM) method [139] aimed at "decomposing, organizing and analysing a complex problem" [82] and converting it into a hierarchical structure of various levels, such as goal, criteria, sub-criteria, and alternatives [118, 119, 120].
The steps involved in the AHP process, are described below: 1. Formulation of the aim of the work and hierarchy construction: Decomposition of decision problem into individual items, taking into account their common characteristics, and formation of the appropriate hierarchical model with different levels (at least three: goal, criteria and alternatives). 2.
In the AHP model, the problem is decomposed into a hierarchy of goal, criteria and alternatives, with the goal placed at the top, criteria placed at the intermediate level and alternatives at the bottom.
