Application of total interpretive structural modelling (TISM) for analysis of factors influencing sustainable additive manufacturing: a case study

Abstract

PurposeThe purpose of this study is to develop a structural model based on total interpretive structural modelling (TISM) approach for analysis of factors influencing sustainable additive manufacturing (AM).Design/methodology/approachA total of 20 factors influencing sustainable AM are identified on the basis of literature review. Appropriate inputs from experts are obtained and TISM model is developed. Also, cross-impact Matrix multiplication applied to classification (MICMAC) analysis is carried out to categorize the factors.FindingsBased on TISM model, “Flexibility in manufacturing”, “Time to develop new product” and “Local availability of technology” are found to be the dominant factors. MICMAC analysis indicates that 10 factors belong to driving and 10 factors belong to dependent category.Research limitations/implicationsIn the present study, 20 factors have been considered. In future, additional factors can be considered to deal with technological advancements.Practical implicationsThe conduct of the study will enable AM experts to systematically analyze the factors influencing sustainable AM.Originality/valueThe development of structural model for analysis of factors influencing sustainable AM manufacturing is the original contribution of authors.
