项目摘要

Technical Product-Service Systems (PSS) consist of a technical product that is enhanced by different services along its life cycle. Nowadays, nearly every manufacturer of capital goods offers different services related to a technical product. When increasing ecological sustainability, the energy demand of PSS is gaining in importance. The Cumulated Energy Demand (CED) is a well-known method to determine the energy demand of an economic good. It indicates the entire energy demand, valued as primary energy, which arises in connection with the manufacturing, use, and disposal of an economic good or which may be attributed respectively to it in a causal relation. Existing research works have already investigated the CED for manufacturing various materials, of technical products, and within manufacturing systems. PSS constitute a new scope of investigation, which contains new challenges regarding the determination, analysis, and reduction of the CED.The overall goal of the proposed research project is to make a significant contribution regarding fundamentals for improving ecological sustainability of PSS. The first objective is, to enable the determination of the CED of PSS. The second objective lies in identifying effects of PSS changes on the CED of PSS in order to understand cause-effect-relationship, which build the basis for analyzing the CED of PSS. The third objective is to enable a systematic reduction of the CED of PSS.Based on two application scenarios from the capital goods industry, requirements are to be analyzed with respect to determination, analyzing, and reducing the CED of PSS. Based on that, a PSS specific method for determining the CED of PSS is developed that overcomes the current separated KEA consideration of products and services. Afterwards, effects of PSS changes on the CED have to be identified and classified. Based on the classified PSS changes, cause-effect-relationships are to be derived and to be described in general impact-mechanisms by using event-driven process chains. These impact-mechanisms form the basis for a method for analyzing the CED of PSS. With regard to the reduction of the CED of PSS, general measures have to be developed in order to trigger the impact mechanisms (control levers). These control levers have to be implemented into a method for reducing the CED of PSS. The validation of the entire concept is carried out using the application scenarios from the capital goods industry. The results of this research project will help capital goods manufacturers to analyze and reduce the CED of PSS systematically.

技术产品服务系统（PSS）由技术产品组成，该技术产品在其生命周期内通过不同的服务增强。如今，几乎每个资本货物制造商都提供与技术产品相关的不同服务。当增强生态可持续性时，PSS的能源需求就会变得重要。累积的能源需求（CED）是确定经济利益的能源需求的众所周知的方法。它表明全部能源需求，价值为原始能源，这与制造，使用和处置经济商品有关，或者可能分别归因于因果关系。现有的研究工作已经研究了用于制造各种材料，技术产品和制造系统中的CED。 PSS构成了新的调查范围，该范围包含有关CED的确定，分析和减少的新挑战。拟议的研究项目的总体目标是为改善PSS的生态可持续性做出重要贡献。第一个目的是使PSS的CED确定。第二个目标在于确定PSS变化对PSS CED的影响，以了解原因效应关系，这为分析PSS的CED提供了基础。第三个目标是在基于资本货物行业的两个应用程序方案中系统地减少PSS的CED，应在确定，分析和减少PSS的CED方面进行分析。基于此，开发了用于确定PSS CED的PSS特定方法，该方法克服了当前分离的KEA对产品和服务的考虑。之后，必须确定和分类PSS变化对CED的影响。基于分类的PSS变化，应通过使用事件驱动的过程链来得出并在一般影响力机制中得出因果关系。这些影响力机制构成了分析PSS CED的方法的基础。关于降低PSS的CED，必须制定一般措施以触发冲击机制（控制杆）。必须将这些控制杆实现为减少PSS CED的方法。使用资本货物行业的应用程序方案进行了整个概念的验证。该研究项目的结果将帮助资本货物制造商系统地分析和减少PSS的CED。
