On condition based maintenance policy

open access: yesJournal of Computational Design and Engineering, 2015
Abstract In the case of a high-valuable asset, the Operation and Maintenance (O&M) phase requires heavy charges and more efforts than the installation (construction) phase, because it has long usage life and any accident of an asset during this period causes catastrophic damage to an industry.
