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，公司试图以增加产品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中实现，而且越来越多地通过产品和过程之间的链接和通信以及不同的网络和平台的使用。物理系统的这种扩展称为网络物理系统（CPS）。这些系统的特征是真实对象和进程与信息处理对象和过程通过信息网络的相互联系。通过这些意味着它们正在增强物理和软件系统的相互作用。然而，与物理产品相比，物理和虚拟对象的联系有助于CPS的复杂性更高。对当前研究状态的分析表现出CPS设计的重叠区域的不足和复杂性的测量。为了考虑在网络物理系统设计中的复杂性，缺少合适的描述性和解释模型。考虑到CPS的增加，该研究建议的总体目标是开发一个模型，该模型能够以最佳的成本效益关系设计CPS。为了实现这一目标，对成本效益比的系统复杂性将用作测量和控制变量。通过测量复杂性效率低下，将得出纠正措施。同时，复杂性可以用于系统的部分部分有助于客户价值。研究项目可以在四个部分模型中构建。在第一步中，将开发出一个描述性模型，即考虑复杂性诱导的维度。随后，将得出用于复杂性驱动因素和相互依赖性结构化分析的解释模型。为了量化复杂性及其在网络物理系统中的影响，将开发并转移到指标系统中。在最后一步中，系统开发将得到一个模型的支持，该模型能够推导CP的复杂性设计措施。计划的研究主张有助于更好地理解网络物理系统的复杂性。该研究将通过将其应用于不同行业来验证。为了促进结果的转移，将提供软件演示工具。
