A survey of service-based systems-of-systems manufacturing systems related to product life-cycle support and energy efficiency

Current trends are showing the growing demand of embedded systems, related to cyber-physical systems, which consist of smart physical actors and/or sensors that are reachable e.g. with service-oriented technologies, cooperating and negotiating to behave showing systems-of-systems characteristics and without any defined hierarchical structures. Possible evolvable structures and emergent behaviors allow generating new features/functions by the collaboration of different components of the cyber-physical systems. These Systems-of-Systems characteristics of service-based cyber-physical systems used among others for manufacturing processes are very suitable to support the product life-cycle in the initial (production) phase of a product and are very suitable to increase the energy efficiency of a whole manufacturing system using context sensitive technologies during the running life cycle phase. This paper presents a brief state-of-the-art analysis for service-based manufacturing systems related to product life-cycle support in the initial phase and energy efficiency aspects.
