Model for Integrated Maintenance Management

This paper presents an object model for maintenance management of roofing systems as a case study to demonstrate the applicability of a proposed generic framework for integrating the maintenance management of built-assets. The model builds upon the Industry Foundation Classes (IFCs) (Releases 2.0 and 2.x) to define object requirements and relationships for the exchange and sharing of maintenance information between applications. Maintenance Management is one of the defined projects within the Facilities Management (FM) domain committee of the International Alliance of Interoperability (IAI). The paper proposes several extensions to the IFC’s including the representation of functional requirements, assessed conditions of objects, inspection and maintenance tasks, and libraries of non-project specific information. Usage scenarios are provided to illustrate the use of the model to carry out selected processes. Résumé Ce document présente un modèle objet de gestion de l’entretien des couvertures de bâtiments; il s’agit d’une étude de cas visant à montrer l’applicabilité d’un cadre générique d’intégration de la gestion de l’entretien des biens bâtis. Ce modèle, basé sur les Industry Foundation Classes (IFC, versions 2.0 et 2.x), définit les exigences et relations objets en vue de l’échange et du partage de l’information de gestion entre les applications. La gestion de l’entretien est l’un des projets définis au sein du comité de gestion des installations de l’International Alliance of Interoperability (IAI). Le document propose plusieurs ajouts aux IFC, en particulier la représentation des exigences fonctionnelles, l’évaluation des conditions des objets, les tâches d’inspection et d’entretien, ainsi que des bibliothèques d’information non propre à tel ou tel projet. L’auteur présente des scénarios d’usage pour illustrer l’utilisation du modèle en vue de la mise en oeuvre de certains processus. Introduction The efficient practice of asset maintenance management requires sharing of technical and administrative information among various computer applications, in addition to sharing information among individuals. This data sharing, in turn, demands common data standards that can enable information to be exchanged from one application to another.
