16、magnetic tape or telecommunications line) must also be agreed, Special computer programs are usually needed to generate/receive each data interchange. Each tends to have its own transport mechanism and the operational and organizational arrangements for each mechanism must also be established. This

17、is compounded because although similar data is interchanged on all Projects, the data interchanges and mechanisms tend to be different for each. It is costly and time consuming to devise and agreed these for each new Project. Costly changes to computer software are also usually necessary and increas

18、ed data errors and inconsistencies occur until each new interchange has settled down. Because of the trend of recent years in reducing the start-up time of new projects, project management could find itself in a position such that the project data interchange system is delaying the project itself. T

19、hus the problems caused by having to devise and agree new data interchanges for each new project can be summarized as: - unnecessary costs - inconsistent data - unnecessary delays The solution is to adopt standards or guidelines developed for general use, instead of re-inventing the wheel for each p

25、ry such as Engines, Avionics etc. The Guide has been designed to cover all types of data (e,g. calculations, geometry, lists of Alpha-Numeric data, text, etc,) and all functions of the industry (design, procurement, production$ product support, project management, etc,). The work of the Group is onl

26、y concerned with the external data interfaces between companies, not with internal company procedures or databases. This is consistent with the approach taken by ATA in defining the EDI-interface between aircraft operators and aircraft manufacturers. The Guide is published in two volumes: - Volume 1

27、 contains recommendations on methods and suggestions on how to organize data interchanges, based on the experience of existing Projects. - Volume 2 is the “Data Dictionary“ and contains the agreed data element and message definitions, It is established as a computerized data dictionary which is avai

The objective of the Association is to promote the development of the Aerospace Industry in Europe by making it mare competitive as a whole and trying to create, for its benefit, a domestic European market. To meet this objective, the Association studies all the problems linked with this develo

38、 AEROSPACE BUSINESS COMMUNICATIONS GUIDELINES VOLUME 1 Issue: 5 / DEC 1988 Author: CDEWG D.1.0 ZUSAMMENFASSUNG UND VORWORT D.1.0.1 Einleitung Riese Zusammenfassung vermittelt einen berblick ber die Ziele und Aktivitaten auf dem Gebiet des elektronischen Datenaustauschs (Electronic Data Interchange -

39、 EDI) innerhalb der europischen Luft- und Raumfahrtindustrie, vertreten durch die Association Europenne des Constructeurs de Matriel Arospatial (AECMA). Verantwortlich fr die Koordination dieser Ttigkeiten ist die Arbeitsgruppe fr Rechner-Datenaustausch (Computer Data Exchange Working Group - CDEWG)

40、 die der Commission Technique et Industrielle (CTI) angegliedert ist. Diese Arbeitsgruppe hat die Aufgabe, EDI-Richtlinien zu entwickeln und sowohl die Anwender als auch das Personal der Datenverarbeitung hinsichtlich der Realisierung des ED1 zu beraten. Es begann mit dem Erleichtern des Information

41、saustauschs zwischen Partnerfirmen von Gemeinschaftsprojekten und -programmen der Luft- und Raumfahrt und dehnte sich schliesslich auf den Austausch von Daten mit anderen Bereichen der Luft- und Raumfahrtindustrie 2.B. Triebwerksbau, Gertelieferanten U.S.W. aus, Die Arbeitsgruppe besteht aus Vertret

42、ern der meisten grossen europischen Luft- und Raumfahrtfirmen. Fr diejenigen, denen AECMA nicht gelufig ist, enthlt Absatz D.1.0.4 dieser Zusammenfassung eine kurze Beschreibung der Organisation. D.1.62 Die Problemstellung Die europischen Luft- und Raumfahrtfirmen sind in zunehmendem Mass an gemeins

43、chaftlichen Projekten und Programmen beteiligt, Als Folge mssen in bedeutendem Umfang Informationen ausgetauscht werden; nicht nur untereinander, sondern ebenso mit Lieferfirmen, Unterauftragnehmern und Auftraggebern, In der Vergangenheit erfolgte der Informationaustausch hauptschlich auf dem Postwe

44、g ait Papier 2.B. als Zeichnungen, Spezifikationen, Tabellen und allen Arten von Unterlagen. Heutzutage werden die meisten Informationen firmenintern mit Rechnern verarbeitet und in Datenbanken gespeichert; die Vorstellung, den Datenaustausch durch direkte Kopplung der Rechner ber das Fernmeldenetz

45、durchzufhren, ist daher naheliegend und diese Tendenz ist bei den Projekten Airbus, Tornado, EFA, “-90, Columbus, U.S.W. deutlich wahrnehmbar.

46、 permitted without license from IHS-,-,-Page : 12 A.E.C.M.A. AEROSPACE BUSINESS COMMUNICATIONS I Issue: 5 / DEC 1988 Author: CDEWG GUIDELINES VOLUME 1 Ein ganz wesentlicher Unterschied zwischen dem alten, auf dem Austausch von Schriftstcken beruhenden und den neuen, elektronischen Verfahren besteht

47、darin, dass beim Austausch von Papier als Informationstrger der Empfnger in der Lage ist, die Information zu deuten; Rechner knnen jedoch nicht - wie Menschen - unmittelbar oder aus dem Zusummenhang heraus interpretieren, Sie mssen die Informationen genau in der Art empfangen, in der sie erwartet we

48、rden. Die Schwierigkeit bestand darin, dass fr jeden Austausch von Rechnerdaten eines Projekts-der genaue Inhalt und die Bedeutung der Daten vereinbart werden mssen; die genaue Spezifikation der fr die Datenbermittlung anzuwendenden Methode (Magnetband oder Fernleitung) muss vereinbart werden. Fr di

49、e Generierunq/den Empfang von Daten sind meistens spezielle Rechnerprogramme erforderlich. Jeder Datenaustausch tendiert dazu, seinen eigenen bermittlungsmechanismus zu haben, daher mssen auch fr jeden dieser Mechanismen die Abwicklungs- und Organisations-Vereinbarungen getroffen werden, Dieses ist k
