Interpretive structural modelling approach: Implementation of sustainability concept and lean in aerospace sectors

Interpretive Structural Modelling (ISM) is applied for interpolating the factors dictating the implementation of lean and sustainability concepts in aerospace sector. Modern aerospace component manufacturers are expected to be lean and sustainable to sustain in the competitive market scenario. Lean and sustainable strategies offers benefits such as waste elimination and minimal environmental impact. ISM has been preferred to create the structural model to explore the interrelationship between factors. 15 major factors are identified from prior art and further validated based on expert opinion. Based on computation, the influential factors are being identified and the structural model developed, management infrastructure and customer pressure factors are found to have top priority. The study has been conducted with inputs from expert and practitioners and the study is focused on aerospace sector. Hence, the outcomes are practically valid based on case study.
