Item Development of a Model for Total Productive Maintenance Barriers to Enhance the Life Cycle of Productive Equipment(Elsevier, 2021) Mishra, Rajesh PThe main intention of the organization is to focused on enhancing its efficiency, life cycle, and productivity by maintaining better delivery time so that customer satisfying can be guaranteed. One way to achieve this intention is by implementing the concept of Total Productive Maintenance (TPM). In this study, barriers faced by Indian manufacturing organizations in the new emerging market had been determined through the questionnaire survey with the help of renowned academician and industrial experts. These barriers had been divided into key areas namely behavioral, organizational, cultural, technological, departmental, operational, and financial barriers. The barriers had positive as well as negative effects on the actual implementation of TPM aligned with life cycle engineering of productive equipment. The study identifies the crucial barriers to TPM employment in Indian manufacturing industries from the literature review and industrial experience. Hence, a unique model was developed for the determination of the driving and dependence power of the barriers to TPM execution to enhance the life cycle of productive equipment using Interpretive Structure Modelling (ISM).Item An AHP model for quantification of benefits of World-class Maintenance Systems(Inder Science, 2007-01) Mishra, Rajesh PIn 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.Item Development of a Framework for Implementation of World-class Maintenance Systems Using Interpretive Structural Modeling Approach(Elsevier, 2015) Mishra, Rajesh PThe purpose of this paper is to develop a framework for the implementation of World-class Maintenance Systems (WMS) with the help of Interpretive Structural Modeling (ISM) methodology. In our earlier work, the framework for WMS was proposed, which explained what constitutes WMS. As a follow up paper, an attempt has been made to present a detailed description about how an organization can implement WMS. To accomplish the same, a standard template is provided for describing the implementation of each and every element and their contextual relationships are also described by ISM methodology which shows driving power and dependence of each element. It is believed that such a normative presentation of the framework would benefit the managers in providing proper guidance and direction during implementation of WMS.Item A SWOT analysis of total productive maintenance frameworks(Inder Science, 2008-01) Mishra, Rajesh PIn the literature of Total Productive Maintenance (TPM), a large number of frameworks have been proposed by different authors and consultants. If an organisation or a maintenance manager has to make a strategic decision of implementing TPM, it may not be easy for them to identify a suitable framework from a plethora of frameworks that are available in literature. Hence, in this paper, an attempt has been made to perform a comparative study of these frameworks using a Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis. In addition to this, the SWOT analysis helped us consolidate a list of critical success factors for TPM apart from identifying the potential weaknesses and threats. Further, it can be concluded that implementation of TPM is by no means an easy task, as it is heavily burdened by weaknesses and threats. However, if an organisation implementing TPM gives due considerations to these weaknesses and threats, it can utilise the significant strengths and opportunities offered by TPM to achieve a competitive advantage.
