制造过程和相关供应链是公认的碳排放源。这些排放部分与产品本身的设计有关。例如，围绕材料选择的决定对排放有很大影响，因此对制造产品中的碳有很大影响。虽然有一些工具支持从环境角度分析设计，但它们往往需要近乎完整的设计描述，这些描述只有在设计和开发过程的后期，当时间和范围有限时才可用，例如，时间安排和成本限制。此外，往往需要作出权衡。比如说，与材料选择相关的决策会影响制造产品所需资源的嵌入碳，但也可能会产生冲击-对交通和相关碳排放的影响。本文报告了早期的工作，探索建立工程设计工具的可行性，这些工具适合在设计过程的早期使用，当设计定义不完整时，有机会探索更广泛的设计选项。一个说明性的案例研究被用来考虑与材料选择和相关运输相关的碳成本的量化。离散事件仿真模型源自早期的设计描述，加上一系列替代材料和供应链方案。早期的结果是有希望的，因为它们可以用来比较碳的替代设计方向的后果。
Manufacturing processes and associated supply chains are a recognised source of carbon emissions. In part these emissions are related to the design of the product itself. For example, decisions surrounding the selection of materials have a high impact on emissions and hence the embedded carbon in manufactured products. While there are tools that support the analysis of designs from environmental perspectives, they tend to require near complete design descriptions that are only available later in the design and development process when time and scope for change is limited, e.g., by scheduling and cost constraints. Further, there are often trade-offs to be made. For example, decisions related to the selection of materials impacts the embedded carbon of resources needed to manufacture a product but may also have a knock-on effect on transport and associated carbon emissions.This paper reports early work exploring the feasibility of establishing engineering design tools that are suitable for use early in the design process when the design definition is incomplete and there is scope for exploring a wider range of design options. An illustrative case study was used to consider the quantification of carbon costs associated with material selection and associated transportation. Discrete event simulation models were derived from early design descriptions coupled with a range of alternative material and supply chain scenarios. Early results are promising in that they can be used to compare carbon consequences of alternative design directions.
