对于大多数公司而言，环境问题已成为现代产品开发的重要问题。在产品开发过程中必须采取特殊程序，以遵守最近的绿色指令。产品结构被认为是关键因素，该因素为减少产品终止的环境影响提供有效手段。但是，由于固定产品结构的假设，大多数以前的研究都无法在设计阶段利用宽敞的纬度。为了克服这种缺陷，我们提出了一种基于CAD的方法，该方法允许通过更改零件组合，选择组装方法并重新安排组装序列来自动变化3D产品结构。计算方案使用遗传算法（GA）技术从该方法生成的设计替代方案中产生最佳产品结构。这对应于较低的组装/拆卸成本，同时遵守指定的回收和恢复率。该计划还选择了需要拆卸的较小零件，并确定经济的拆卸过程。在商业CAD系统中实施的测试结果以具有成本效益的方式证明了该方案在绿色产品设计中的有效性。 （c）2009 Elsevier B.V.保留所有权利。
Environmental issues have become an imperative concern for most companies in relation to modern product development. Special procedures have to be taken during the product development process to comply with recent green directives. Product structure is recognized as a critical factor that provides effective means for reducing environmental impact in product end-of-life. However, most previous studies failed to leverage the vast latitude at the design stage due to the assumption of a fixed product structure. To overcome this deficiency, we propose a CAD-based approach, that allows automatic variation of 3D product structure by means of changing the combination of parts, selecting the assembly method, and rearranging the assembly sequence. A computing scheme uses Genetic Algorithm (GA) techniques to produce an optimal product structure from the design alternatives generated by the approach. This corresponds to lower assembly/disassembly costs, while complying with specified recycling and recovering rates. The scheme also chooses a smaller set of parts that needs to be disassembled and determines an economical disassembly process. Implemented in a commercial CAD system, the test results demonstrated the effectiveness of this scheme in green product design in a cost-effective manner. (C) 2009 Elsevier B.V. All rights reserved.
