“…These paradigm shifts are driven by changing market demands and the corresponding requirements to the manufacturing systems. To remain competitive, one of the major characteristics of future manufacturing companies is their changeability [119]. Autonomous Manufacturing Systems will support these frequent or even permanent changes of the system.…”

Today's assembly systems have to be flexible to adapt quickly to an increasing number and variety of products and changing demand volume. To manage these dynamics, flexible, reconfigurable, and autonomous assembly systems were proposed and partly realised in the last two decades. The flexibility and adaptability is realised by clustering the assembly system into subsystems and modules which get a certain degree of autonomy and control themselves in a decentralised way. This keynote paper will present the general principles of autonomy and the proposed concepts, methods and technologies to realise autonomous processes in assembly systems. Different approaches for design and autonomous operation of assembly will be explained and future trends towards fully autonomous components of an assembly system as well as autonomous parts and products will be discussed.

Adapt!Evaluation - Evaluation for Design and Re-Design of Production Systems based on Axiomatic Design

Abstract. Since trends of our society are changing, the automotive industry has to handle new requirements within their production like vague quantities of production, fast integration of new technologies and an increasing variety of diversity. Therefore conventional life-cycles of production systems are broken up and re-design and changeability of complex systems have to be considered during their whole life time. Within this framework the paper proposes a novel approach to enable change during the life cycle of a production system and to enhance the usability of a re-design and change process by consistent interaction between the design and evaluation method. Thereby the focus is on the linkage of design and evaluation process to pursue a decrease of complexity and to point out the benefits which can be found by using Axiomatic Design Theory in this holistic context of the production system life-cycle. To validate the results of the paper and show up their benefits, a use case will describe and discuss the research.

Population growth, connected with rising incomes, urbanization, fidelity to dogmas and climate change, places pressure on the food industry. This significantly increases the inextricably-linked demand of production systems for water and energy. Technological solutions-such as increasing accessibility and further reducing costs-can be employed to overcome the limitations created by the local availability of resources. This paper develops a new methodology generating sustainable value, and thus achieving a competitive advantage in business ecosystems. The methodology addresses both the key requirements of sustainable development and the preferences of stakeholders. A set of design conditions are proposed to develop eco-efficient, socio-eco-effective, and adaptable production systems under changing limitations. An international project is launched to demonstrate the superiority of the design methodology and to create awareness about interdependencies among the prevalent design conditions and regional limitations. The task aims at developing technological solutions, which can be retrofitted in existing production systems to increase the sustainable local added value and capacity for regions affected by climate change. The impact of climate change is more obvious in semi-closed ecosystems. Cyprus is one of the Mediterranean islands with such a semi-closed ecosystem. Combined with water scarcity and rising prices in electricity, this made Cyprus an ideal testing ground for the methodology. The selected solution includes the use of hybrid energy and water generation to process agricultural products and to recycle organic waste. This solution achieves a nearly zero emission, zero water footprint and increases the local added value by product-service systems. To support decision-makers, various technologies and their feasibility are considered, evaluated and recommendations are made for implementing the modular solutions.
