PROPOSAL OF DESIGN SUPPORT METHOD OF SUSTAINABILITY SCENARIOS IN BACKCASTING MANNER

Describing sustainability scenarios is a hopeful approach for envisioning sustainable future visions of industries. However, describing stistainability scenarios is a difficult task and there is no computational support method. This article proposes a design support method of sustainability scenarios in a backcasting manner, which means thinking backward from targeted futures. For the design support method, we propose the following. two methods; (i) a method for supporting backward thinking and constructing future visions using a logic tree and (ii) a method for drawing transition paths based on the logic tree. As a case study, we designed "Sustainable manufacturing scenario," which envisions sustainable future visions of manufacturing industries. Through the case study, we identified the effectiveness of the proposed method. The proposed method supports designing the scenario in clarifying the future visions, drawing the transition paths, and describing them in scenario structurally
