Abstract: The manufacturing and use of electromechanical products consume vast amounts of energy and resources, while generating significant amounts of pollutant emissions, resulting in severe environmental pollution problems. The use of whole life cycle design methods can minimize the negative environmental impact of products, and ultimately improve product quality and sustainability. Therefore, a method of product green design scheme expression based on directed network structure is proposed to realize effective integration of functional domain, structural domain, process domain and material domain information related to product life cycle design and multi-domain association mapping with the whole life cycle stage. The expression method of life cycle scene based on set theory is established, and the expression model of design scheme integrating life cycle scene is constructed by designing node interface step by step matching. According to the characteristics of the established network model of product design, the depth-first search algorithm with the pruning strategy is used to generate individual initial design schemes by traversing each design node in the design network model. A coding strategy based on the adjacent real number matrix is developed for the correlation between design nodes in the individual design scheme. By setting the differential evolution operator, the green design scheme of 2.5 MW wind turbine is optimized under the condition of meeting the environmental constraints of the product life cycle.
