    Evaluation of “Design Loops” to Support the Design of Product Service Systems: A Case Study of a Helium Liquefier
    (Cranfield University Press, 2009-04-01) Maussang, N.; Zwolinski, P.; Brissaud, D.; Rajkumar Roy; Essam Shehab
    In this paper a specific evaluation for the PSS during the early design phase is presented, taking into account:  the scenarios that supports the definition of the architecture of the whole system and the interactions between the user and the system  the performance of the considered system assess with specific PSS criteria (economical and environmental) Our proposition consists in the evaluation of the design loops that are constructed jointly with the scenarios describing activities and with the PSS architecture. This evaluation phase is part of a methodology that is being developed to design global and optimized PSS.

    The Use of DfE Rules During the Conceptual Design Phase of a Product to Give a Quantitative Environmental Evaluation to Designers
    (Cranfield University Press, 2009-03-31) Alhomsi, H.; Zwolinski, P.; Rajkumar Roy; Essam Shehab
    In order to help designers to understand and translate the environmental constraints into effective actions, methods and tools have to be developed to enable the generation of more environmentally benign design alternatives according to Design for Environment rules. This article explains how to use DfE rules earlier during the conceptual design phase, when the designers don’t have simple qualitative tools or methods to evaluate their products. Two main actions have been realised: 1) to identify which kind of rules can be applied when designers only have a functional representation of their product 2). To create the necessary indicators to evaluate these rules depending on designers choices.
