Die Herstellung medizintechnischer Produkte erfordert es, die Funktionalität der Produkte über eine Überprüfung aller sicherheitsrelevanten Bauteilmerkmale sicherzustellen. Für eine kostenoptimierte Produktion sind folglich neben den Fertigungskosten auch die Qualitätskosten frühzeitig in den Betrachtungsrahmen der Technologieplanung zu integrieren. Es wurde daher ein Ansatz entwickelt, der eine integrative, kostenoptimierte Auslegung von Fertigungsprozess- und Prüffolgen zulässt.   The production of medical products requires to ensure their functionality by means of an inspection of all safety-relevant component characteristics. For a cost-optimized production, the quality costs as well as the production costs have to be taken into consideration during the stage of technology planning. Therefore, an approach has been developed which enables an integrated, cost-effective design of production process and inspection sequences.

In most trendsetting industries like the aerospace, automotive and medical industry functionally critical parts are of highest importance. Due to strict legal requirements regarding the securing of the functionality of high-risk parts, both production costs and quality costs contribute significantly to the manufacturing costs. Thus, both types of costs have to be taken into consideration during the stage of technology planning. Due to the high variety of potential interactions between individual component properties as well as between component properties and manufacturing processes, the analysis of the influence of the manufacturing history on an efficient design of inspection processes and inspection strategies is extremely complex. Furthermore, the effects of inspection strategies and quality costs on the planning of manufacturing process sequences cannot be modeled to date. As a consequence, manufacturing and inspection processes are designed separately and thus a high cost reduction potential remains untapped. In this paper, a new approach for an integrative technology and inspection planning is presented and applied to a case study in medical industry. At first, existing approaches with regard to technology and inspection planning are reviewed. After a definition of relevant terms, the case study is introduced. Following, an approach for an integrative technology and inspection planning is presented and applied to the case study. In the presented approach, the complex causalities between technology planning, manufacturing history, and inspection planning are considered to enable a cost-effective production process and inspection sequence design.

Policies to reduce carbon emissions are leading to substantial changes in the demand for electricity and to the structure of electricity supply systems, which will alter the cost structure of electricity supply. This can be expected to result in corresponding changes to the price structure faced by customers. This note is an initial exploration of how possible new price structures may impact on HVAC system and building design and use. Changes in the price structure of electricity supply (separately from changes in price levels) can significantly affect the cost-effective design and operation of building services systems; especially of heating and cooling systems. The nature and implications of these changes can have important implications for future system design and operation.
