Abstract: The aim of this paper is to evaluate the flexibility in flexible manufacturing system (FMS). Two distinct modelling approaches have been employed. Flexibility and factors are identified through literature review, and a relationship is established in the opinion of experts from industries and academia. In this study, a hybrid model which employs interpretive structural modelling (ISM) and modified technique for order preference by similarity to ideal solution (TOPSIS) together, are proposed. ISM has been used to develop a hierarchical structure of flexibility. Modified TOPSIS has been used to evaluate the flexibility based on some factors. ISM model concluded that production flexibility has the more driving power than other flexibilities. Modified TOPSIS also evaluated that production flexibility is the most important flexibility in the FMS. The criteria weights are calculated by using the analytical hierarchy process (AHP).
