    A digital factory is a good approach for optimizing value streams. Various aspects contribute to the design of digital factories - on the process side and on the product/system side. This ranges from machining centers to autonomous transport systems. Each of these products/systems must have a corresponding architecture that facilitates integration. Therefore, the system architecture design should not be neglected and is an essential part of the development process. With the methodical development of modular architectures, products/ systems are supported in their integration into digital factories. This article shows how the Integrated PKT-Approach for Developing Modular Product Families enables this.

    Megatrends such as globalization and technological advances increase the pressure on manufacturing companies. A possible way out is to provide customized combinations of products and services. These so-called Product-Service Systems (PSS) enable companies to access new markets and can be used to differentiate themselves from competitors. However, providing PSS also creates challenges for companies, for example, an increase in complexity within the company, resulting in higher costs. In the first part of this paper, a literature review is used to identify drivers of complexity in the context of PSS. One of the identified main drivers is a rising variety of components and processes within the company. In order to reduce this internal variety and thus also the variety-induced complexity, new tools for the design of variety-oriented PSS are presented in the second part of this paper. The objective of the tools is to reveal the variety and help to reduce the internal variety of product and service components and processes without restricting the external variety of offerings. The newly developed tools are presented schematically and then the application of the tools on an industrial example is discussed. Finally, an outlook on further research topics is given.

    Variety-driven design to reduce complexity costs of a tire curing press family

    As a result of the prevailing megatrends, many companies are diversifying their product program further and further. Additional product variants are being developed in order to implement the increasing variety of offers. However, these variants increase the complexity within the company. The development of variety-oriented product structures is one way to counteract this increasing complexity. In this contribution, we will show how variety-oriented product structures can be developed with the help of the Design for Variety Method (DfV), using the example of a tire curing press. Furthermore, a new visualization of variety is introduced and it is shown how DfV and complexity cost analysis can be used to evaluate variety-oriented product concepts. Finally, an outlook on further possible research topics is given.
