识别与产品系统相关的材料和物质流为生命周期分析（LCA）提供了有用的信息，并有助于扩大LCA与工业生态学的两个主要工具--物质流分析/物质流分析（MFA/SFA）之间的互补范围。本文提出了一种新的方法，投入产出分析的基础上确定的物理投入产出流的个别材料，与生产的一个单位的给定产品，单位物理投入产出的材料（UPIOM）。虽然桑基图一直是多纤维附件/标准纤维附件可视化的标准工具，但随着所考虑的流动的复杂性增加，当涉及整个经济的部门间材料流动时，桑基图可能变得过于复杂，无法有效可视化。提出了一种可视化表示材料流的替代方法，该方法利用基于制造程度的流矩阵的三角剖分。所提出的方法适用于生铁和铁和废钢，是与在日本的乘用车的生产流程。它的有用性，以确定一个特定的MFA模式从原来的IO表证明。
Identification of the flow of materials and substances associated with a product system provides useful information for Life Cycle Analysis (LCA), and contributes to extending the scope of complementarity between LCA and Materials Flow Analysis/Substances Flow Analysis (MFA/SFA), the two major tools of industrial ecology. This paper proposes a new methodology based on input-output analysis for identifying the physical input-output flow of individual materials that is associated with the production of a unit of given product, the unit physical input-output by materials (UPIOM). While the Sankey diagram has been a standard tool for the visualization of MFA/SFA, with an increase in the complexity of the flows under consideration, which will be the case when economy-wide intersectoral flows of materials are involved, the Sankey diagram may become too complex for effective visualization. An alternative way to visually represent material flows is proposed which makes use of triangulation of the flow matrix based on degrees of fabrication. The proposed methodology is applied to the flow of pig iron and iron and steel scrap that are associated with the production of a passenger car in Japan. Its usefulness to identify a specific MFA pattern from the original IO table is demonstrated.
