Abstract
In manufacturing field, the concept of Product Service Systems (PSS) has begun to attract attention as create value of manufacturers’ products and build up strong relationships with their customers. Comparing traditional business model, the PSS designers need to consider more the value of all stakeholder in which involved. Moreover, they are also required to analyze all cost related to product and service in all life cycle phases of their PSS. In PSS design research field, some researches have proposed a method to design PSS based on perspective of life cycle cost (LCC). However, they analyzed LCC only from the perspective of producer or customer and in order to design PSS, it is necessary to consider the values of multiple stakeholders involved in PSS simultaneously because of above mentioned reasons. From this background, this study aims to establish a method to design PSS considering value of multiple stakeholders. Specifically, this paper proposes method to structure needs of multiple stakeholders, functions and entities that realize their needs. Further, the authors analyze the dependency relationship between these PSS building blocks, and associates them with each life cycle phase of target PSS using a life cycle cost model.
