Linkage analysis among factors in obtaining return quantity / volume: An interpretive structural modelling on construction machinery remanufacturing industries

Core acquisition management is one of the most crucial activities in remanufacturing industries. The availability of cores is important to support company's operational functions. This study aims to investigate the supporting factors of a successful core acquisition, focusing on return quantity / volume. Several key factors, considered as the root of the acquisition problem, have been identified through Interpretive Structural Model (ISM) method that involves the opinions of experts. From the initial identification, we obtained nine factors, in which two factors are in the dependent cluster, five factors are in the linkage cluster, and two factors are in the independent cluster. The results of the ISM-based model and MICMAC analysis showed that relationship type (factor 1) and convenience of logistics (factor 4) are the keys to successfully obtain an adequate amount of return quantity / volume. The results showed that the ISM method helps to simplify complex problems and suggest the remanufacturing companies to focus and pay more attention to these two factors, for the success of a core acquisition strategy.
