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，在整个生命周期内通过各种服务进行补充和扩展。PSS被认为是一种减少资源消耗和环境影响的方法。许多实证研究发现，PSS的环境效益是个案具体，并不普遍有效。然而，另一种认识指出，如果环境可持续性的意识已经纳入PSS的早期设计阶段，PSS的方法是有益的，在减少对环境的影响。目前的研究现状在设计初期对PSS的生态可持续性考虑不足，这是本项目建议书的首要问题，本项目的总体目标是在早期阶段分析PSS在环境可持续性方面的潜力，并利用研究结果减少PSS对环境的影响。第一个分目标是探讨PSS的环境影响。第二个分目标是制定措施，减少PSS的环境影响。第三个子目标是将PSS的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。基于来自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，并分析了供应商系统中的生产要素，明确了PSS的客户和合作伙伴。在此基础上，通过引入PSS环境影响平衡的基本方法，对PSS的关键过程进行识别和分类，对PSS的环境影响进行了研究。为了系统地推导和评价减少PSS环境影响的措施，首先应以因果分析的形式识别其影响因素，并探索其变化潜力。从这一点出发，制定了减少PSS对环境影响的措施，并在措施目录中系统化。为了使措施的选择，客观的冲突分析的评价概念和方法的开发。最后，将研究结果转化为一种方法，并将其整合到PSS生态设计的一般过程模型中。
