项目摘要

In the development of new products companies try to satisfy individualized customer requirements with an increased number of product variants. These product variants are not only realized in the physical domain, but increasingly through the interlinkage and communication between products and processes and the use of different networks and platforms. Such an extension of a physical system is referred to as a cyber-physical system (CPS). These systems are characterized by the interlinkage of real objects and processes with information processing objects and processes through information networks. By these means they are enhancing the interplay of physical and software systems. However, the connection of physical and virtual objects contributes to a higher complexity of CPS compared to physical products.The analysis of the current state of research exhibits a deficit in the overlapping area of the design of CPS and the measurement of complexity. In order to consider complexity in the design of cyber-physical systems, suitable descriptive and explanatory models are missing.Taking into account the increased complexity of CPS it is the overall goal of this research proposal to develop a model that enables the design of CPS with an optimal cost-benefit relation. To achieve this goal the system complexity which has an essential influence on the cost-benefit ratio will be used as measurement and control variable. Through the measurement of complexity inefficiencies will be detected and correcting measures will be derived. At the same time complexity can be used in parts of the system where it substantially contributes to customer value.The research project can be structured in four partial models. In the first step, a descriptive model taking into consideration complexity-inducing dimensions will be developed. Subsequently, an explanatory model for the structured analysis of complexity drivers and interdependencies in CPS will be derived. To quantify complexity and its effects in cyber-physical systems indices will be developed and transferred into a system of indicators. In the last step, the system development will be supported by a model that enables the derivation of measures for a complexity-oriented design of CPS.The planned research proposition contributes to a better understanding of the complexity of cyber-physical systems. The research will be validated by applying it in different industries. To facilitate the transfer of results a software demonstration tool will be provided.

在新产品的开发中，公司试图通过增加产品的变体数量来满足个性化的客户需求。这些产品变体不仅在物理领域实现，而且越来越多地通过产品和过程之间的相互联系和通信以及不同网络和平台的使用来实现。这种物理系统的扩展被称为网络物理系统（CPS）。这些系统的特点是通过信息网络将真实对象和过程与信息处理对象和过程相互联系。通过这些方法，它们增强了物理系统和软件系统的相互作用。但是，物理对象和虚拟对象的连接使得CPS相对于物理产品具有更高的复杂性。对研究现状的分析表明，在CPS设计与复杂性度量的重叠领域存在缺陷。为了考虑信息物理系统设计的复杂性，缺乏合适的描述和解释模型。考虑到CPS的复杂性增加，本研究计划的总体目标是开发一个模型，使CPS的设计具有最佳的成本效益关系。为了实现这一目标，将对成本效益比有重要影响的系统复杂性作为测量和控制变量。通过对复杂性的度量，将发现效率低下的地方，并推导出纠正措施。与此同时，复杂性可以用于系统中对客户价值有实质性贡献的部分。研究项目可分为四个部分模型。在第一步中，将开发一个考虑到复杂性诱导维度的描述性模型。随后，将推导出一个用于CPS中复杂性驱动因素和相互依赖性的结构化分析的解释性模型。为了量化复杂性及其在网络物理系统中的影响，将开发指数并将其转换为指标系统。在最后一步中，系统开发将得到一个模型的支持，该模型能够为面向复杂性的CPS设计派生度量。计划的研究命题有助于更好地理解网络物理系统的复杂性。该研究将通过在不同行业的应用得到验证。为了方便结果的转移，将提供一个软件演示工具。
