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，该产品在整个一生中补充和扩展了各种服务。 PSS被视为减少资源消耗和环境影响的一种方法。许多实证研究导致发现PSS的环境益处是特定于病例的，并且通常不有效。然而，另一种认可指出，如果对环境可持续性的认识已经集成到PSS的早期设计阶段，则PSS的方法在降低环境影响方面是有益的。在当前研究状态的早期设计阶段对PSS的生态可持续性的考虑不足代表了项目提案的最初问题。拟议项目的总体目标是在早期阶段就其环境可持续性分析PSS的潜力，并利用发现来减少PSS的环境影响。第一个子目标是探索PSS的环境影响。第二个子目标是制定减少PSS环境影响的措施。第三个子目标是转移发现和减少PSS的环境影响到一种方法中的发现，并将其整合到过程模型中，该过程描述了PSS.的生态设计的任务和步骤。基于资本货物行业的六个应用程序场景的生态设计，分析了物理产品和服务之间的相互作用，以及PSS的生产因素，并在PSS的系统中分析了PSS的零件，并且是零件的零件。基于此，通过调整基本方法来平衡对PSS的影响，识别和分类PSS的关键过程，从而探索了PSS的环境影响。为了系统的衍生和评估以减少PSS的环境影响，应首先以因果分析的形式识别其影响因素，还应探讨其变化潜力。由此，在措施目录中开发并系统化了降低PSS的环境影响的措施。为了实现措施的选择，开发了一种评估概念和客观冲突分析的方法。关于PSS的环境影响的研究和减少的发现，最终将其转移到一种方法中，并集成到PSS生态设计的一般过程模型中。
