Developing a Novel Framework for Quality System and Systems Thinking to Integrate: A Paradigm Shift in Maintenance

摘要

This paper presents a need of paradigm shift in maintenance system so as to improve performance of overall system in this global competition. It discovers flaws in present day maintenance strategies that were considered to be the rationale behind the need for this new paradigm; changing scheme from a problem solving maintenance to a problem understanding maintenance. To reply to that research gap, this study unveils want in quality system and systems thinking that must have got to be integrated into conception of the existing maintenance strategies. Having had demand for integration of these methodologies, this paper offers a novel framework that enable maintenance operatives to plan maintenance actions through the identification of true root cause of failures and the quest of optimal solutions by viewing problem as a system in its entirety. Unlike current maintenance strategies, the proposed framework will count not only 'hard' factors but also their relationships with nascent 'soft' factors as contributing elements in the cause of failure. It can then be developed from beneficial effect of integration between the Six Sigma and the System Dynamics benefiting from favorable merged characteristics of the two; quality system and systems thinking respectively, along with feedback mechanism. Details construction of the framework is explained thoroughly in every section of this paper.
