From Organizational Strategy to Product Implementation: A Sustainable Design Decision Support Method Based on Value Chain-Stakeholder Coupling

摘要

Purpose: Addressing the prevalent "strategy-execution gap" in sustainable design practices within modern manufacturing industries like smart homes—whereby macro-level corporate sustainability strategies are difficult to effectively translate into concrete product design solutions—this study aims to develop and validate a systematic decision support method.Methodology: This research constructs an integrated decision support framework. First, through an innovative "Value Chain-Stakeholder Coupling" analysis, it systematically identifies the internal and external driving factors and diverse demands affecting sustainable design. Second, it establishes a three-level decision model encompassing strategic, tactical, and operational layers to facilitate the hierarchical translation of sustainability strategies into specific design solutions. Finally, it integrates simplified Life Cycle Assessment (LCA), Life Cycle Costing (LCC), Social Impact Assessment, the Analytic Hierarchy Process (AHP), and Fuzzy Comprehensive Evaluation to form a multi-dimensional evaluation and selection mechanism capable of handling uncertainty.Findings: Applied to a smart home lighting product as an illustrative case, the proposed method was used to compare several feasible sustainable design alternatives. The results indicate that the method can effectively support the identification of a balanced solution with improved environmental and social performance while maintaining acceptable economic feasibility. This validates the method's effectiveness and practical feasibility in balancing multiple environmental, social, and economic objectives.Conclusion: The decision support method proposed in this study provides enterprises with an operational and replicable toolkit that can effectively bridge the decision-making chain from organizational strategy to product implementation. It highlights the critical role of systems thinking, a full life cycle perspective, and the dynamic coordination of diverse stakeholder needs in achieving sustainable design goals, offering powerful theoretical guidance and practical tools for manufacturing enterprises to formulate and execute sustainable design strategies in complex environments.
