An Integrated Functional Modelling Framework Applied for Operations and Maintenance

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


Safe operations and adequate maintenance are two main means to achieve reliable production and reduce downtime of a plant. In a good manner, operations are the customer of maintenance, and maintenance is the service provider. However, in reality, the tasks of operations and maintenance are carried out by two different groups so that the close relationship between the two tasks is split.
In this paper, this challenge is handled by a proposed integrated functional modelling framework. In this framework, the Multilevel Flow Modelling (MFM) method with its cause-consequence reasoning rules is used. The qualitative relationship distribution between operations and maintenance can be established by using a distributed qualitative evaluation method based on the function states of the system. In addition, these relationships are visible for both groups and utilize the detected information in the early stage of the development of the unpleasant scenarios to improve the situation awareness, and prevent the undesired emergency shutdown from both perspectives of operations and maintenance. Consequently, it can reduce production loss. A case study of operations and maintenance of a seawater injection system is carried out and shows the industrial applicability of the proposed framework. The case study strongly reveals that there is a highly close relation between operation and maintenance for ensuring the system working properly. It demonstrates that the proposed integrated framework is not only able to support operational tasks but also for the maintenance tasks by including relevant maintenance information of the system. The results show that it can potentially help with
decreasing downtime of the system.
