Applications of waste relations matrix (Wrm) in lean wastes identification

Abstract

This research paper presented the applications of Waste Relations Matrix (WRM) in the identification of seven deadly wastes of lean manufacturing. This narrative research is based on the review of previous studies. Literature review is summarized, discussed and presented in tables. Since, the seven deadly wastes of lean manufacturing have been the severe problem in industries due to their association with the production performance; thus it has been the focus of academicians and practitioners to study and implement such waste identification philosophy. Since, lean manufacturing is an effective waste elimination technique and its tools have captured the immense attention of academicians and practitioners for manufacturing wastes reduction. Therefore, there is an extreme need to conduct such studies about the usefulness and drawbacks of the implementation of lean practices. In future, other lean practices can be discussed in depth to put clearer and broader picture and to draw more comprehensive conclusion. Moreover, existing studies lack to investigate the implementation in various sectors. Studies related to WRM are significantly important in development of lean wastes knowledge due to individual sectors have major differences in their processes. In this regard, present review is conducted so as to put the open and broader picture of Waste Relations Matrix (WRM) comprehensively.
