    Analytical network process in decision making
    (IGI Global, 2023) Jayawardena, T.S.S; Jayawardena, C.S
    Analytic Network Process (ANP) is a generalizedform of the Analytical Hierarchical Process (AHP). AHP is an objective theory of deriving the decision makings on absolute scale values starting from subjective relative measurements perhaps on tangible or intangible or a mix of both rated by the experts. A consistency measure of the relative ratings is verified with a consistency ratio to assure the ratings of the experts are consistent. The clustering of criteria/sub-criteria with inner and outer dependencies as well as feedback is taken into account in ANP. In ANP rather than a hierarchical process, a network structure is assumed and all nodes in the network are treated equally with interaction between nodes and grouping into clusters. A supermatrix is constructed, then normalized it to get weighted super matrix and raised it to a sufficient power to converge this into a unique eigen vector representing the final weights in limit super-matrix. Step by step iterations of ANP was demonstrated with a selection of car example.

    Analytical hierarchical process in decision making
    (IGI Global, 2023) Jayawardena, S; Gopura R.A.R.C
    In the introduction, what decision making is and the significance of the decision making was introduced. Few popular decision-making techniques were listed out and three rational techniques were discussed in a nutshell. Then Professor Saaty's seminal work, Analytical Hierarchical Process (AHP) was described, starting with the evolution of AHP and moving towards its practice through a four-step process. The AHP generates weights on a relative ratio scale with an input of measurements on a standard scale and due to the normalization process linearity of the results was destroyed. Finally, the four-step analytical hierarchical process was illustrated through an example of the selection of a job. During the progression, outcomes of the key theoretical aspects have been touched on without providing proof.
