SUMMARY AND FOREWORD E.l.O.l Jntroductios This Summary

26、 provides an overview of the aims and activities in the field of Electronic Data Interchange (EDI) within the European Aerospace Industry, represented by the Association Europenne des Constructeurs de Matriel Arospatial (AECMA). Coordination of these activities is the responsibility of the Standing

27、Committee for Electronic Data Interchange. The aim of this Committee is to develop EDI-Guidelines and advise on EDI-implementation to both end users and data processing staff. It started with facilitating the interchange of inforiation between partners in Collaborative Aerospace Projects and Program

28、es and expanded to interchanges with other sectors of the Aerospace Industry, such as Engine Manufacturers, Equipment Vendors, etc. The Committee consists of representatives from most of the major European Aerospace Companies. For those who are not familiar with AECMA a brief description of this org

29、anieation is given in paragraph E.1.0.4 of this summary. E.1.0.2 The Pro blea European Aerospace Companies increasingly engage in collaborative projects and programmes. Consequently massive volumes of information have to be interchanged, not only between themselves but also with vendors, subcontract

30、ors and customers. In the past, information was interchanged primarily using the Postal Services to transport paper in the form of drawings, specifications, schedules, and all sorts of documents. Nowadays, most information within companies is processed by computers and stored in computer data bases

31、and naturally the idea of interchanging data by directly linking computers through telecouunication networks has gained momentum. This trend is noticeable in projects such as Airbus, Tornado, EFA, “-90, Hermes, Columbus, etc. A major difference between the old paper-based methods and the new electro

32、nic ones is that when exchanging paper the receiving person is able to interpret the information. Computers however lack this human ability to interpret intuitively or by context. They need to receive the information in precisely the way it is expected. COPYRIGHT Association Europeene Des Constructe

34、meaning of the data must be agreed; the precise specification of bow the data will be transmitted on the computer medium (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

35、transport mechanism and the operational and organizational arrangements for each mechanism must also be established. This 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 t

36、o devise and agree these for each new Project. Costly changes to computer software are also usually necessary and increased 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 ma

37、nagement could find itself in a position such that the project data interchange system is delaying the project itself. Thus the problem caused by having to devise and agree new data interchanges for each new project can be summarized as: - unnecessary costs - inconsistent data - unnecessary delays T

38、he solution is to adopt standards or guidelines developed for general use, instead of re-inventing the wheel for each project. E.1,0.3 The AECMA Amroach to the Problem The AECMA Standing Committee for Electronic Data Interchange publishes these Guidelines to Data Interchange with the following objec

39、tive : “TO provide a method for efficient Electronic Data Interchange between Co-operating Aerospace Companies. To satisfy this objective the Committee monitors the development of ED1 standards in other industries, studies existing internationally agreed standards and using these wherever possible,

40、produces recommendations for the European Aerospace Indus try These recoiiendations cover the following areas: - Data Definition - Message Definition - Syntax Rules - Data Transmission Protocols - Security/Confidentiality Methodologies - Data Interchange Guidelines for new projects.

41、ation Europeene Des Constructeurs de Materiel AerospaceLicensed by Information Handling ServicesEURO CTI/5/159LB 91 m lb7043 0503bll O70 m The Guide will evolve as collaborative methods improve and as further advances are made in computing techniques. The Guide is being developed to satisfy a requir

42、ement from AECMA User- Commissions and Committees. Whilst the Guide originated as a result of mutual assirtance between Airframe companies, it has been structured so that it can easily include data interchanges between other sectorr of the Aerospace Industry such as Engines, Avionics etc. The Guide

43、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 Committee is only concerned with the external data inter

44、faces between companies, not with internal company procedures or databases. This is consistent with the approach taken by ATA in defining the EDI-interface between civil aircraft operators and aircraft manufacturers. AECMA has taken an active approach to evaluate the US DoD initiatives on informatio

45、n technology, known as CALS. The CALS data interchange technical standards are being evaluated whilst user workinggroups are evaluating the proposed CALS standard procedures. A liaison between AECMA and CALS has been formalized by AECMA representatives in a number of workinggroups under the CALS Ind

46、ustry Steering Group. The Guide is published in three volumes: - A Management Summary contains an overview of the subject and a broad outline of the organization of the activities. - Volume 1 contains recommendations on methods and suggestions on how to organize data interchanges, based on the exper

47、ience of existing Projects, - Volume 2 contains the “Message, Segments and Data Dictionary“ for the Standards developed by AECMA itself. It is established as a computerized data dictionary which is available on floppy disk and in print. It also contains the references to all other data-interchange s

48、tandards adopted by AECMA with indication of their possible field of application. Details can be found in part 4, Furthermore, a Brochure (6 pages) is published to increase awareness of these AECMA activities and the periodical circulation of a Newsletter is foreseen in the near future.
