Modelling Approach for the Integrated Development of Industrial Product-Service Systems

Shifting business focus from offering mere physical products to offering IPS2 an innovative strategy to meet customer requirements is revealed. The objective of this paper is to present a modelling approach for integrated development of IPS2-concepts in early development phases. The characteristics of the IPS2 concept modelling approach are deduced from a case study on a fictitious micro-manufacturing task. The proposed modelling approach abolishes established and mostly diffuse borders between products and services to assess systems behaviour already in early phases. Furthermore, applying the concept of modularisation to services in order to reduce complexity induced by specific IPS2-characteristics is discussed.

Provision of Basis for a New Snake-Like Reconnaissance Robot for Disaster Situations

It frequently comes to building collapses all over the world. Often people are buried alive. They must be rescued and saved by rescue teams. It depends on the time that passes during a rescue whether a person can still be rescued alive. Especially the information which is available about the exact position of a person buried alive is decisive for a fast accomplishment of rescue actions. Accordingly the exact localization of victims buried alive is of primary importance. It is the only way, a fast rescue and salvation can be started. However, biological and technical locating equipment available today shows numerous weak points. This refers particularly to the precision of position determination of the victims. But the essential disadvantage of the utilizable technologies is that a collapsed building cannot be entered actively. There is no equipment available that enables a deep penetration into ruins for inspection and exploration tasks, without the necessity of using heavy machines. In a research project currently funded in Germany these difficulties shall be encountered by a part autonomous, energy self-sufficient and remotely controlled reconnaissance robot. It will become a motion system, which orientates its design and behavior at the biological archetype snake. The paper at hand introduces the state-of-the-art of technology and research in the fields of locating, reconnaissance robots as well as snake robots. Originating from a multifunctional locomotion system that has been already implemented successfully, elements for a robot system to be newly developed are introduced and discussed.Copyright

Design for recyclability of capital goods

Nowadays a future oriented product development and design of capital goods should consider a design for recycling and maintenance. The existing support instructions are neither structured uniformly nor adapted to the design process. Therefore, this paper presents a method oriented basis for structuring existing support instructions and for developing practical and flexible support instructions for the design in terms of recycling and maintenance aspects of capital goods. The structure and classification is also shown, as examples of the support instructions within the computer based application.

Handlungshilfen für das recycling- und instandhaltungsgerechte Konstruieren

In consideration of the legal regulations and competitive differentiation the importance of recyclable products even in the capital goods industry gets more significant. The lack of design aids inhibit an aimed implementation of specific requirements. This article links together, with regard to synergies, the design for recycling and the design for maintenance. Support instructions - on the bases of methodological strategies - are provided for industrial use.

Methodical Scope for Design Processes for Recycling and Maintenance

Nowadays a future oriented product development and design of capital goods should consider a design for recycling and maintenance. So new practical design strategies and methods are needed Tn this raper there is given a method-oriented basis for the development of practical and flexible design strategies and methods for the design for recycling and maintenance of capital goods. Also some examples of strategies and methods are given as an illustration.
