“…New functions which cannot be provided by conventional solutions can mean added product value, too. However, drawbacks of multifunctional parts can be linked to a more complex design process, and to precautions which can be necessary to compensate the reduced robustness if two or more functions run on one single part [32].…”

CFRP was the prime choice for the airframe of the latest aircraft of Boeing and Airbus. However, modern aluminium alloys were developed with improved cost-performance relationships, and, in addition, todays CFRP manufacturing technology is not fully ready for high production rates of shortand medium-range aircraft. Furthermore, the light weight design potential of today's CFRP airframe is heavily penalised by additional system installation effort, which is necessary due to the poor electrical conductivity of CFRP compared to aluminium or fibre metal laminate such as Glare ® . For the next generation of aircraft, it is necessary to reduce material cost and airframe manufacturing cost, and to improve the added product value by additional functions such as electrical conductivity. This chapter reveals latest R&D results to enable cost-effective thermoplastic composite airframe structures with blends, more electrically conductive and more damage tolerant composites with metal fibre reinforcements and up-stream research for different use cases of morphing structures by means of shaped memory alloy wire integration.

This contribution presents the results of an empirical study about assessments of performance of engineering departments in the German plant manufacturing industry. Engineering plays a central role in the industrial value chain. However, its multiple impact is not considered in an adequate way by current assessments. For instance, economic considerations have a strong focus on costs and consider the engineering department only in an isolated way. Since there is little literature about this topic -existing publications analyze performance from a technical-functional perspective or focus on design aspects -this study aims to evaluate performance criteria and challenges for performance assessments. 36 experts in the domain of plant engineering have been asked in an online survey and personal interviews. A lack of common understanding of engineering performance and the difficulty to quantify the impact of engineering turned out to be the main challenges besides a strong cost focus in the plant manufacturing business. Finally 13 challenges were identified which oppose comprehensive assessments of engineering performance. If recognized, these challenges can help plant manufacturing companies to minimize the ill effects of current economic considerations and to improve their engineering departments more effectively.

“…Every requirement is verbally described and, if possible, concretized by attributes and their characteristics. Several checklists assist the setting up of requirements; see for example [PBF+07], [Rot00], [Ehr03]. System of objectives: This aspect includes the representation of external, inherent and internal objectives and their connections (see chapter 2).…”

The conceivable development of information and communication technology will enable mechatronic systems with inherent partial intelligence. We refer to this by using the term "self-optimization". Self-Optimizing systems react autonomously and flexibly on changing operation conditions. They are able to learn and optimize their behavior at runtime. The development of mechatronic and especially self-optimizing systems is still a challenge. A significant milestone within the development is the principle solution. It determines the basic structure as well as the operation mode of the system and is the result of the conceptual design. Additionally it is the basis for the concretization of the system which involves experts from several domains, such as mechanics, electrical engineering/electronics, control engineering and software engineering. This contribution presents a new specification technique for the conceptual design of mechatronic and self-optimizing systems. It also uses the railway technology as a complex example, to demonstrate how to use this specification technique and in which way it profits for the development of future mechanical engineering systems.
