ライフサイクルシナリオに基づく製品設計のための統合支援環境の提案

摘要

Minimizing environmental loads and costs throughout a product lifecycle requires appropriate lifecycle design. Design of a product lifecycle involves planning lifecycle strategies, evaluating them from various viewpoints and optimizing the overall picture. Product lifecycle strategy can be planned explicitly by describing lifecycle scenarios at an early stage of lifecycle design and the product should be designed to realize the scenario. This paper proposes a design environment for scenario-based lifecycle design. The main approach is to define a representational scheme of a product and its lifecycle in order to integrate them. Our method links a lifecycle model to appropriate product architecture and manages the consistency between them. A case study indicates that the relationship between the lifecycle and the product model is successfully represented on a computer and designers can design a product and its lifecycle in an integrated manner.%持続可能な製造業の実現に向け，高度な循環型の製品ライフサイクルシステム構築の必要性が指摘されている．このような課題に対応す るためには，製品の全ライフサイクルの設計が必要であり，特に製品開発の初期段階においてライフサイクル全体の環境性や経済性を十分 に検討し，最適なライフサイクルの戦略カを策定することが重要である．そして，この戦略を適切に実現し得るように製品の構造や形状を 設計することが不可欠である．
