为了管理制造业对经济和环境的影响，需要设计工具来帮助工程师在设计早期评估制造成本和环境影响。开发成本分析和环境评估可能是繁重的，但这些分析中使用的许多数据可以共享。在将环境评估与成本分析相结合以评估环境影响和成本的制造计划方面，几乎没有做过什么工作。为了同时分析制造工艺计划对产品成本和环境的影响，开发了一个基于电子表格的成本和环境影响评估模型。基于自下而上工艺的成本计算方法被用来估计一系列生产量上的微通道器件制造成本，而基于工艺的从摇篮到门的生命周期评估被用来评估环境影响。这两种模型都从一个公共数据库中提取数据，用于描述设备几何结构和生产环境。该方法被用于评估微通道热交换器的制造计划，提供了对成本和环境影响的可能驱动因素的洞察。对本案例的分析表明，成本和环境影响都是由同一工艺--扩散连接主导的。
To manage the effects of manufacturing industries on the economy and environment, design tools are needed that will aid engineers to assess manufacturing costs and environmental impacts early in design. The development of cost analyses and environmental assessments can be burdensome, but much of the data used in these analyses can be shared. Little work has been done to integrate environmental assessments with cost analyses for the purposes of evaluating manufacturing plans for both environmental impact and cost. A spreadsheet-based cost and environmental impact assessment model is developed for simultaneously analyzing the effects of manufacturing process plans on both product cost and the environment. A bottom-up process-based cost calculation method is used to estimate microchannel device manufacturing costs over a range of production volumes, while process-based cradle-to-gate life cycle assessment is utilized to evaluate environmental impacts. Both models draw data from a common database for describing the device geometry and the production environment. The method is used to evaluate the manufacturing plan for a microchannel heat exchanger, providing insight into the likely drivers of cost and environmental impact. For this case study, the analysis shows that both cost and environmental impact are dominated by the same process step – diffusion bonding.
