An AHP model for quantification of benefits of World-class Maintenance Systems

Abstract

In recent times, organisations are failing in their attempt to adapt and implement Total Productive Maintenance (TPM). Researchers are attributing these failures to the shortcomings of TPM, which resulted in the development of World-class Maintenance Systems (WMS). Different frameworks have been proposed to define and operate world-class maintenance in the literature. A comparative analysis of frameworks in our earlier study revealed various best practices based on which a new framework for WMS has been proposed. Contemporary organisations willing to adapt WMS find it difficult to initiate such a change, as it requires proper justification to convince top management. Further, to initiate the adaptation of WMS as a policy decision, it is necessary to quantify the benefits of WMS. Hence in this paper, an attempt has been made to demonstrate the application of Analytic Hierarchy Process (AHP) for the quantification of benefits of WMS. This model showed that implementing WMS would result in overall improvement in the performance of an organisation.
