Aerospace series - Architecture for integrated management of a system's health condition

This document is mainly aimed at all the trades which are actively involved in managing the health of a system.
Although it relies on examples of aeronautical systems, the expert group considers that this document is applicable for systems from other areas.
This document specifies the centralization of the health data for a fleet of systems, such as an aircraft fleet for example, to ensure consistency between stakeholders (operators, repair facilities, designers, etc.) and the management of its health card.

Luft- und Raumfahrt - Architektur für das integrierte Management eines Systemzustandes

Série aérospatiale - Architecture pour la gestion intégrée de l’état de santé d’un système

Le présent document s’adresse essentiellement à l’ensemble des corps de métier qui sont acteurs de la gestion de l’état de santé d’un système.
Bien qu’il s’appuie sur des exemples de systèmes aéronautiques, le groupe d’expert considère que ce document est applicable aux systèmes des autres milieux.
Ce document spécifie la centralisation des données de santé d’un parc de systèmes, comme par exemple une flotte d’aéronefs, afin d’assurer la mise en cohérence entre acteurs (opérateurs, réparateurs, concepteurs, etc.), et la gestion de son carnet de santé.

Aeronavtika - Arhitektura za integrirano upravljanje stanja sistema

To priporočilo je namenjeno predvsem vsem sektorjem, ki so aktivno vključeni v upravljanje stanja sistema.
Čeprav se opira na primere aeronavtičnih sistemov, strokovna skupina meni, da so ta splošna priporočila uporabna za sisteme iz drugih področij.
