Industrial companies rely on hardware and services from external providers to deliver functions that are critical to their operations, increasingly demanding solutions that not only meet technical and availability requirements but are sustainable too. Traditionally, industrial companies choose and purchase hardware and maintenance support to fulfil their functional requirements. An alternative arrangement, known as Functional Product (FP), involves external providers supplying customers with the functionality they require through contracts that specify guaranteed functional availability whilst giving providers freedom to choose and retain ownership of the supplied hardware and services. This paper describes an innovative simulation modelling and optimization approach to quantitatively compare economic and environmental values resulting from transition from traditional to FP arrangements. The approach is demonstrated through the analysis of a scenario involving a hydraulic drive system provider and set of customers in Sweden, with the results exhibiting simultaneous improvement in economic and environmental values at each stage of the transition.

通过功能性产品量化经济和环境价值 - 一种模拟方法

工业公司依赖外部供应商提供的硬件和服务来提供对其运营至关重要的功能，越来越需要不仅满足技术和可用性要求而且还具有可持续性的解决方案。传统上，工业公司选择和购买硬件和维护支持来满足其功能需求。另一种安排，称为功能产品 (FP)，涉及外部供应商通过指定保证功能可用性的合同向客户提供他们所需的功能，同时让供应商自由选择和保留所提供硬件和服务的所有权。本文描述了一种创新的模拟建模和优化方法，以定量比较从传统到 FP 安排过渡所产生的经济和环境价值。该方法通过对瑞典一家液压驱动系统供应商和一组客户的情景分析得到证明，结果表明在转型的每个阶段，经济和环境价值都得到了同步改善。
