Use case modelling for risk based maintenance management system

Utility companies are shifting their maintenance strategies from corrective or time-based to risk based. Meanwhile, the asset datasets which support these strategies are being migrated from spreadsheets to databases. As a first necessary step of this migration, the authors analyzes the requirements from risk based maintenance strategies add to the maintenance management software systems, through extending the use cases of existing software products. The main contribution and characteristic of these extensions is to provide “flexible information sharing”, i.e. facilitate the growing demands to exchange asset data among stakeholders for the future development of asset management systems.
