Application of FUZZY Methods for Measuring Leanness of Manufacturing Industries

Abstract

Manufacturing plays a vital role in the growth of any economy. In India also the manufacturing is growing rapidly and passing through transforming stage. To maintain the customer demands, quality, profitability, and sustainability it is necessary to adapt good manufacturing practices. This paper emphasizes the adaptation of lean manufacturing and development of model for assessing the lean status of different manufacturing sectors. For assessing leanness, manufacturing sectors are evaluated on 29 lean criterions by using Fuzzy TOPSIS. Fuzzy TOPSIS can deal with a variety of questions. Lean criterions are identified, linguistic ratings for different criterion are selected and scores are assigned, and finally lean status is compared, and it is found that automobile sector is leaner as compared to textile and heavy industries. This paper will help the industry, academia and lean practitioners to assess the lean status of their industry and to strengthen their knowledge towards various benefits of lean manufacturing in the industry.
