PSS solution evaluation considering sustainability under hybrid uncertain environments

摘要: Product service system has a potential to enhance competitiveness and contribute sustainability.This paper aims evaluate PSS in the early design stages considering sustainability.All of three pillars sustainability are considered evaluation.Both fuzziness randomness evaluation. In order deal with resource shortage environmental deterioration, product (PSS) proposed as sustainable development concept. Careful evaluation earlier must be performed before putting solution into practice guarantee sustainability. Due reason that involves many factors is complex long lifespan, criteria will great quantity various measurements. This two issues: (1) how choose (2) uncertain when measuring these criteria. The zigzag mapping process adopted help decision makers obtain from customer domain function domain. modified include economic, social aspects To factors, Information Axiom extended hybrid environments characterized by co-existing. range modeled fuzzy variable random variable. Thus information content calculating integrals boundaries. A simulation algorithm constructed calculate this kind integrals. Two case studies illustrated highlight effectiveness accuracy approach. results show method could reflect judgements more precisely, make use comprehensively. also use-oriented easy influenced aspect sustainability, while product-oriented economic
