Abstract
To reconsider the current mass production paradigm, manufacturers need to make their products have more added values largely from knowledge and service contents to compensate volume reduction under the concept of dematerialization. According to this background, Product-Service Systems (PSS), that create value by combining a product and service, have been attracting attention and several methods have been developed to evaluate PSS from the aspect of environmental burden. However, these methods are not necessarily appropriate to enable designers to find a concrete point to be improved. To solve this problem, this paper proposes a method to evaluate functions of a service from the viewpoints of customer value and environmental burden. Furthermore, based on the evaluation result, we propose recommendation strategies to improve the design solution.
