A Theoretical Analysis for Prioritization of Lean Strategies: A Survey of Indian Manufacturing Industries

The purpose of this paper is to discover the lean strategies prioritization in Indian manufacturing industries. It also aims to select the best strategy for industries. It also helps to improve the performance of implemented lean strategies. This research provides a ranking of implemented lean strategies with grey relational analysis (GRA). Evaluating data were collected from seven different industrial experts in terms of four lean performance criteria such as cost, time, quality and flexibility. Here, fuzzy five Likert scale weighted methods are used which are integrated into the GRA with respect to weight the lean performance criteria. This study provides the priority of lean strategies based on selected criteria using the GRA method which is very effective, and the result will help decision-makers to recognize the best strategy in Indian manufacturing industries. To make results more effective, data were collected from 11 different manufacturing industries which will help in future and criteria can be more for a better result. Moreover, as an interesting proposal, the fuzzy linguistic environment may be further incorporated into the practical as per GRA results. In distinction to preceding research, it sets apart for priority based on the scores of GRA with performance criteria. Furthermore, there is very less work available in the literature with GRA for prioritization.
