Evaluation of Product-Service Systems during early design phase

The development of service engineering within the manufacturing systems domain requires a new approach to design such systems. A PSS design methodology that provides methods and tools to support engineering designers during the design phase is a necessity. One of the key issues during the development process is to assess and evaluate the solutions during the early design phase. The diversity of elements included into a PSS (physical objects, service units and their relations) must be taken into account during this evaluation. We propose in this paper a specific evaluation of PSS during the early design phase. This evaluation phase is part of a methodology that is being developed to design global and optimized sets of products and services. For this evaluation, criteria, economical and environmental factors are presented and applied on a case study.
