UML model for integration between RCM and CBM in an e-Maintenance architecture

Abstract

Maintenance management of an industrial plant has always been a complex activity for the amount of information to be handled. Nowadays, Computerized Maintenance Management Systems (CMMS) help to organize information and thus to carry out maintenance activities in a more efficient way. However, besides collection of data and information about maintenance, other analysis must be carried out and only some of them can be done using a CMMS; tools for Reliability Centred Maintenance (RCM) analysis are available to this end. Companies also adopt systems for condition monitoring, namely Condition Based Maintenance (CBM) systems. Each system is proved to provide benefits to the maintenance management, improving at least the efficiency of the maintenance processes. However, when all the CMMS - RCM - CBM systems are put together, the lack of integration among them prevents from the maximum exploitation of their capabilities. This work aims at fulfilling the gap, providing a data model to allow the development of an integrated system that combines the features of the three systems. The data model is outlined in the framework of an e-Maintenance architecture, so it is an extension of the well known MIMOSA database structure (Maintenance Information Management Open System Alliance).
