Wer einmal mit umfassenden Veränderungsprozessen beschäftigt battle, kennt den Unterschied zwischen Planung bzw. Zielsetzung und Realisierung. Da die v- änderten Rahmenbedingungen immer häufiger zu umfassenden Veränderungen, wie z. B. der Einführung ganzheitlicher Produktionssysteme oder der Neuposit- nierung des Unternehmens, zwingen, vergrößert sich zwangsweise die Zahl der begrenzten Erfolge oder ggf. der Misserfolge. Eine examine dieser Erfahrungen führte zu dem Projekt, über das in diesem Buch berichtet wird. Wir sind den Fragen nachgegangen, inwieweit Verän- rungsprozesse mit der Politik und Strategie einer corporation aber auch mit f- heren „Change“-Projekten kompatibel sind und warum solche „Modernisierun- konzepte“ nicht von den Mitarbeitern akzeptiert oder getragen werden. Dies führt in aller Regel zur Feststellung eines weiteren Defizits: der fehlenden Integration von struktureller und kultureller Weiterentwicklung. Diese Herausforderungen an Integration und erfolgreiche Umsetzung durch Partizipation führten zum Titel des Projektes: „Partizipatives Vorgehen zur - wertung und Gestaltung Integrierter Modernisierungskonzepte“, für den sich im Laufe der Zeit die Abkürzung „PaGIMo“ durchgesetzt hat. Das Projekt wurde vom Bundesministerium für Bildung und Forschung (BMBF) unter dem Ke- zeichen 02PI2065 gefördert und vom Projektträger Forschungszentrum Karlsruhe, Produktion und Fertigungstechnologie (PTK-PFT) begleitet. Projektpartner waren das Forschungs- und Beratungsunternehmen GITTA mbH und das Institut für Technologie und Arbeit e. V. (ITA), Kaiserslautern.

rigidity and pressure research of rotors subjected to floor and physique so much, in addition to to thermal a lot deriving from temperature version alongside the radius, constitutes a vintage topic of computer layout. however realization is restricted to rotor profiles for which governing equations are solvable in closed shape. moreover only a few real engineering concerns may well relate to buildings for which tension and pressure research within the linear elastic box and, much more, less than non-linear stipulations (i.e. plastic or viscoelastic stipulations) produces equations to be solved in closed shape. furthermore, whilst a product continues to be in its layout level, an analytical formula with closed-form resolution is naturally less complicated and extra flexible than numerical tools, and it permits to speedy outline a normal configuration, that may then be fine-tuned utilizing such numerical tools.
In this view, all topics are in line with analytical-methodological method, and a few new strategies in closed shape are awarded. The analytical formula of difficulties is usually conducted contemplating genuine engineering functions. furthermore, with a purpose to make using analytical versions much more pleasant on the product layout degree, a functionality is brought wherein it's attainable to outline a fourfold infinity of disk profiles, strong or annular, concave or convex, converging or diverging. Such matters, even derived from medical authors’ contributions, are continuously geared toward designing rotors on the inspiration level, i.e. in what precedes specific layout.
Among the numerous contributions, a unique point out is due for the next: linear elastic research of conical disks and disks with variable profile alongside its radius in accordance with an influence of a linear functionality, additionally subjected to thermal load and with variable density; research of a variable-profile disk subjected to centrifugal load past the material's yield aspect, introducing the thoroughly normal legislations expressed through a an n-grade polynomial; linear elastic research of hyperbolic disk, subjected to thermal load alongside its radius; linear elastic research of a variable-thickness disk in line with an influence of a linear functionality, subjected to angular acceleration; etc.

Design und Konstruktion entscheiden über den wirtschaftlichen Erfolg neuer technischer Produkte. Nicht allein die "Aufmerksamkeitsökonomie" ist dafür ausschlaggebend; der Wert langlebiger Güter wird von den technischen Eigenschaften ebenso bestimmt wie die richtige Preisgestaltung von den Herstellkosten.


Der Diskurs zum Thema "Ingenieur und dressmaker" zeigt Möglichkeiten, wie das ambivalente Verhältnis zwischen den Partnern im Entwicklungsprozess effizienter und damit reibungsloser zu gestalten ist. Im geschichtlichen Rückblick und mit dem Beschreiben der heutigen scenario erhält der Leser Einblicke zur Positionsbestimmung von layout und Konstruktion, von fashion designer und Ingenieur.


Die verschiedenen Wahrnehmungsweisen des gestalterischen Prozesses von der Idee zum Produkt führen besonders dann zu Reibungen, wenn es um ästhetische Fragen geht. Die unterschiedlichen Bildwelten von Ingenieuren und Designern erschweren die Verständigung und führen zu ungenauen oder falschen Ergebnissen. Die Fähigkeiten des Erkennens wesentlicher ästhetischer Prozesse und Strategien im kulturellen Kontext und historischem Hintergrund erleichtern die Verständigung.
