Complexity-oriented design of cyber-physical systems

在新产品的开发中，公司试图通过增加产品变体的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流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。物理系统的这种扩展被称为信息物理系统（CPS）。这些系统的特点是通过信息网络将真实的对象和过程与信息处理对象和过程相互联系起来。通过这些手段，他们正在增强物理和软件系统的相互作用。然而，由于物理对象和虚拟对象的连接，CPS的复杂性高于物理产品，在CPS设计和复杂性度量的交叉领域存在不足。为了考虑复杂性的信息物理系统的设计，适当的描述和解释modelsmissing.Considering CPS的复杂性增加，这是本研究建议的总体目标，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，系统的复杂性有一个重要的影响的成本效益比将被用作测量和控制变量。通过对复杂性的测量，将发现效率低下的情况，并得出纠正措施。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。在第一步中，将开发一个考虑到复杂性诱发因素的描述性模型。随后，将推导出CPS中复杂性驱动因素和相互依赖性结构化分析的解释模型。为了量化网络物理系统的复杂性及其影响，将制定指数，并将其转化为一个指标系统。在最后一步中，系统开发将得到一个模型的支持，该模型可以导出CPS复杂性导向设计的措施。计划中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中的应用来验证。为便于成果的转移，将提供一个软件演示工具。

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.
