Barrier analysis for product service system using interpretive structural model

Abstract

Product service system (PSS) has recently been proposed as a business model. The PSS model requires adjustments of not only internal company technology but also maintenance, service, and supply chain management of up- and downstream suppliers. The implementation of PSS faces a number of challenges. This paper focuses on the challenges in maintenance and remanufacturing. Implementation barriers were identified through a comprehensive literature review followed by expert confirmation. The complex relationships among these barriers were determined through expert panel discussion. Interpretive structural modeling is then used to partition the barriers into a hierarchical structure to facilitate strategic analysis. Results of the analysis were summarized to provide guidelines for PSS implementation.
