Technical Product-Service Systems (PSS) consist of a technical product, which is supplemented and extended over the entire lifetime by various services. PSS are regarded as an approach for reducing resource consumption as well as environmental impact. Many empirical studies have led to a finding that the environmental benefits of PSS are case-specific and not generally valid. Nevertheless, another recognition states that the approach of PSS is beneficial in terms of reduction of the environmental impact if the awareness of environmental sustainability is already integrated into the early design phase of PSS. The inadequate consideration of the ecological sustainability of PSS in the early design phase of the current research status represents the initial problem of the project proposal.The overall objective of the proposed project is to analyze the potential of PSS in terms of its environmental sustainability at an early stage and to use the findings to reduce the environmental impact of PSS. The first sub-goal is to explore the environmental impact of PSS. The second sub-goal is to develop the measures to reduce the environmental impact of PSS. The third sub-goal is to transfer the findings for the analysis and reduction of the environmental impact of PSS into a method as well as to integrate it into a process model, which describes the tasks and steps for eco-design of PSS.Based on six application scenarios from the capital goods industry, interactions between physical product and services are analyzed, and the production factors in the systems of the provider, the customer and the partners of PSS are specified. Based on this, the environmental impacts of PSS are explored by adapting the fundamental methods for balancing the environmental impact to PSS, identifying and classifying the critical processes of PSS. For the systematical derivation and evaluation of measures to reduce the environmental impact of PSS, their influencing factors should first be identified in form of a cause-effect analysis, and their change potentials should be explored as well. From this, measures to reduce the environmental impact of PSS are developed and systematized in a catalog of measures. In order to enable the selection of measures, an evaluation concept and a method for objective conflict analysis are developed. The findings on the investigation and reduction of the environmental impact of PSS are finally transferred to a method and integrated into a general process model for eco-design of PSS.

技术产品服务系统 (PSS) 由技术产品组成，并通过各种服务在整个生命周期内进行补充和扩展。 PSS 被认为是减少资源消耗和环境影响的一种方法。许多实证研究发现，PSS 的环境效益是针对具体情况的，并不普遍有效。然而，另一种认识指出，如果环境可持续性意识已经融入 PSS 的早期设计阶段，那么 PSS 方法对于减少环境影响是有益的。目前研究现状的早期设计阶段对 PSS 生态可持续性的考虑不够充分，这是该项目提案的最初问题。该项目的总体目标是分析 PSS 在环境可持续性方面的潜力。早期阶段并利用研究结果来减少 PSS 对环境的影响。第一个子目标是探索 PSS 对环境的影响。第二个子目标是制定减少 PSS 对环境影响的措施。第三个子目标是将PSS环境影响分析和减少的结果转化为一种方法，并将其整合到一个过程模型中，该模型描述了PSS生态设计的任务和步骤。资本货物行业的六个应用场景，分析了物理产品和服务之间的相互作用，并指定了PSS的提供商、客户和合作伙伴系统中的生产要素。在此基础上，采用平衡PSS环境影响的基本方法，对PSS关键过程进行识别和分类，探讨PSS的环境影响。为了系统推导和评估减少PSS环境影响的措施，首先应以因果分析的形式确定其影响因素，并探索其变化潜力。由此，制定了减少 PSS 对环境影响的措施，并将其系统化为措施目录。为了能够选择措施，开发了客观冲突分析的评估概念和方法。 PSS环境影响的调查和减少结果最终转化为一种方法，并集成到PSS生态设计的通用过程模型中。
