Engineering of systems is highly influenced by rapid technological changes, such as the emergence of Cyber-Physical Systems (CPS). These are interconnected embedded systems enabled by human-machine interaction. Realisation of CPS require a collaboration between mechanical engineering, electrical engineering, and computer science since different components are delivered and developed by different disciplines. Consequently, the Requirements Engineering (RE) process needs to consider multi-disciplinary perspectives. The objective of this paper is to elaborate the specific challenges of RE for CPS in a distributed environment and to identify knowledge sources and targets in CPS engineering. It describes the relevant types of knowledge and defines appropriate exchange mechanisms and standards.

Our understanding of the interplay between product-services and social sustainability is still very limited. This paper sheds light on the interconnections between social sustainability and product-services throughout their life-cycle, and identifies a set of common topics and practices to be investigated by experts of Advances in Production Management Systems. In doing so, the paper sets the stage for future efforts aimed at exploiting the opportunities identified and exploring new synergies between product-services and social sustainability.

This paper presents the background and the challenges for manufacturing companies that want to servitize their business by combining their products with services. One important challenge from the developer’s perspective hereby is to combine Product Lifecycle Management and Service Lifecycle Management approaches to support the lifecycle of integrated Product-Service Systems (PSS). The paper is focusing on the definition and visualization of the interactions in the design phase of a Product Service System. The method of the Design Structure Matrix (DSM) has been adopted for a Product Service System.  The proposed integration of product and service design provides a definition of high high level activities for developers, which can be regarded as a first step towards an integrated PSS lifecycle management.

Overview about Service Labs worldwide: Approaches, Methods and Use Cases to test Service across Lifecycle

As product-service systems are very complex, an integrated approach how to test a service is needed. The paper provides a framework for the development and testing of new services, and thereby grants a lot of space and tools for service innovation. In product-service-systems different types of resources are involved, for instance people, technology, information and organization. In the framework provided by mixed reality laboratory environments, all of these resources are brought together as well.

The resources people, technology, information and organization are integrated. The interdisciplinary knowledge concerning these relevant resources is merged in the laboratory environments. Furthermore mixed reality laboratory environments are unifying academic expertise and practical, business-driven interests. Since service relevance in manufacturing companies is growing, the testing of new service concepts gets more important. Various methods are available, which help to verify service concepts. Due to this, the focus of this paper is on the analysis of established Service and Innovation Labs worldwide. To give an overview 24 Service labs are identified and analysed.
