Dynamic analytic hierarchy process: AHP method adapted to a changing environment

Abstract

Purpose – Actual situations evidence how adopted decisions can change the decision constraints of the system where the analytic hierarchy process (AHP) is being applied. Therefore, the purpose of this paper is to provide a dynamic view of the AHP method, considering the criteria and alternatives as temporary variables and finally obtaining not only one good choice for a specific moment but a more comprehensive picture of those alternatives resulting more important for the business, according to strategy and over time. Design/methodology/approach – With this purpose this paper starts with a short literature review and the general characteristics of the AHP method. Afterwards, the paper presents the problem that appears frequently in actual situations which justify the development of this research. Once described, the uncertainty appeared after the AHP implementation, the proposed methodology called dynamic analytic hierarchy process (DAHP) is presented. Findings – Finally, this paper shows a case study and concludes with the main points of the research suggesting applications and further extensions. Originality/value – The value of this paper is the description of a DAHP as a tool that can facilitate decision making related to some of the critical aspects in maintenance or post-sales area, permitting the alignment of actions with the business’ objectives.
