Analyzing the factors affecting the flexibility in FMS using weighted interpretive structural modeling (WISM) approach

A high degree of flexibility is required for advancement in technology, rapid delivery to market, meeting customers demands and flexible manufacturing system is ideal for solving these problems. There are some variables which not only affect the flexibility but also affect each other. In this paper, twelve factors have been identified through the literature review and they are further analysed with the help of weighted interpretive structural modeling approach. In this research, a questionnaire based survey was conducted to rank these factors and ISM based approach has been employed to analyse their mutual interaction and interpretation of factors in terms of their driving and dependence powers has been examined. The structural model developed using this methodology helps to understand the interaction between various factors affecting the flexibility and their managerial implications. A method of effectiveness index is used to identify the key factors. The effectiveness index evaluated in this paper will help the industries to benchmark their performance by focussing on the factors reported in this paper.
