Evaluation of “Design Loops” to Support the Design of Product Service Systems: A Case Study of a Helium Liquefier

摘要

In this paper a specific evaluation for the PSS during the early design phase is presented, taking intoaccount: the scenarios that supports the definition of the architecture of the whole system and the interactionsbetween the user and the system the performance of the considered system assess with specific PSS criteria (economical andenvironmental)Our proposition consists in the evaluation of the design loops that are constructed jointly with the scenariosdescribing activities and with the PSS architecture. This evaluation phase is part of a methodology that isbeing developed to design global and optimized PSS.
