要求に着目した環境調和型製品設計支援の研究 （第１報） 要求を中心にした情報構造と発散収束設計過程の提案

Abstract

Environmental consciousness has been widely recognized as an indispensable requirement for product design. Requirements of the environmentally conscious product are more varied and complicated rather than those of a conventional product. In clarifying variety and complicated requirements, environmental consciousness has to be considered effectively in the early design stage. Systems that support environmentally conscious design, therefore, need to be based on models of clarification process of requirements by multiple designers over a product life cycle. The ReqC (Requirement-Centered) model for basic information structure and process of environmentally conscious design has been developed, which is based on observations and analysis of how designers make decisions about requirements during design meetings. This paper proposes the ReqC model, which consists of two submodels, i.e., the ReqDIS (Requirement-centered Design Information Structure) model for design information structure and the ReqCP (Requirement-Centered Process) model for convergent/divergent design process.
