摘要

如今,除了经济问题外,企业在设计产品以在竞争激烈的世界中立足时还面临着社会和环境方面的挑战。产品可持续性的重要步骤之一是材料选择。确定制造多部件产品的最佳材料组合是复杂的,因为每个部件都有几种材料可供选择。本文提出了一种整数规划方法来选择由多个部件组成的产品的材料。该模型综合解决了材料选择、供应商选择、制造工艺选择、装配工艺选择和寿命终止选择等问题。这种模式的目标是在整个产品生命周期中尽量减少生产者的成本和对环境的影响。为了验证所提出的模型,在汽车行业进行了一个案例研究。最后,通过敏感性分析,探讨了减重对成本和环境的影响。结果表明,轻质材料并不总是环境考虑的最佳选择。

Multi-objective optimization for selecting sustainable materials with simultaneous consideration of several components in a product
ABSTRACT Today, in addition to economic issues, companies face social and environmental challenges in designing their products to stay in a competitive world. One of the essential steps in product sustainability is material selection. Determining the optimal combination of materials to make multi-component products is complicated because there are several material alternatives for each component. In this paper, an integer programming approach is proposed to select materials for products that are composed of many components. In this model, several issues are integrated and solved simultaneously: material selection, supplier selection, manufacturing process selection, assembly process selection, and end-of-life option determination. The objectives of this model are to minimise the producer’s cost and the environmental impact through the entire product life cycle. In order to validate the proposed model, a case study has been conducted in the automotive industry. Finally, by sensitivity analyses, weight reduction on cost and environmental impact has been investigated. The results indicate that lightweight materials are not always the best option in terms of environmental consideration.
