Essay aus dem Jahr 2016 im Fachbereich Informatik - software program, be aware: 1,3, FOM Hochschule für Oekonomie & administration gemeinnützige GmbH, Düsseldorf früher Fachhochschule, Sprache: Deutsch, summary: Die Anfang der 1990er Jahre entwickelte Aufwandschätzmethode von Gustav Karner basiert auf zu einem Softwareprojekt entwickelten Use situations und errechnet auf diesen Angaben eine Bearbeitungsdauer. 2010 wurde diese Methode in der Dissertation von Stephan Frohnhoff weiterentwickelt. Frohnhoff modifizierte die Methode in Hinblick auf viele Kriterien um sie präziser und moderner zu gestalten. Die Modifizierungen fanden größtenteils in der Berechnung, den Formeln und den Gewichtungen statt. Das ehemalige Kostenfaktormodell, das in Kapitel 2.3 näher erläutert wird, wurde komplett überarbeitet. Ein Kritikpunkt, der in dieser Arbeit problematisiert wird, konnte nicht beseitigt werden:

Die Methode ist in Bezug auf ihre Formeln und Gewichtungen ausgezeichnet durchdefiniert. Dennoch wurde das größte challenge, dass Use instances und ihre Transaktionen, je nach Ersteller individuell ausführlich, komplex und groß ausfallen, nicht gelöst. Es wird der those nachgegangen, dass guy, sofern guy diese Methode kennt, durch schriftliche Veränderungen der Use Case oder durch minimale Änderungen in subjektiven Bewertungen, das Endergebnis sehr leicht manipulieren kann.

cellular structures, whose parts converse and alter their constitution, now pervade the informational global and the broader international of which it's a half. The technological know-how of cellular structures is as but immature, in spite of the fact that. This e-book offers the pi-calculus, a idea of cellular structures. The pi-calculus presents a conceptual framework for realizing mobility, and mathematical instruments for expressing structures and reasoning approximately their behaviours. The publication serves either as a reference for the idea and as a longer demonstration of ways to take advantage of pi-calculus to explain platforms and examine their homes. It covers the fundamental thought of pi-calculus, typed pi-calculi, higher-order techniques, the connection among pi-calculus and lambda-calculus, and purposes of pi-calculus to object-oriented layout and programming. The publication is written on the graduate point, assuming no previous acquaintance with the topic, and is meant for laptop scientists attracted to cellular systems.
