3.2. ANP method
The ANP method is widely used to solve MCDM (Multi-Criteria Decision Making Methods) which is sub-discipline of the operational research and interested in structuring & solving decision making problems including multiple criteria. The ANP was developed to define the correlation among the components and elements (Saaty, 1996) since numerous decision-based problems require dependency and feedback within and among the cluster and elements. The aim of the method is to provide user a smart tool in order to select alternatives not only attributes and criteria but also to their consequences. Thus, the internal dependency within the elements and external dependency between the different elements are provided.
