Probabilistic Basis for Managing Maintenance

by W. S. LaPay, NATD, United States,



Document Type: Proceeding Paper

Part of: Water Resources Infrastructure: Needs, Economics, and Financing

Abstract: The paper discusses a procedure based on component failure probabilities, consequences of failure, and risk associated with loss of system. Aging effect of structures and equipment on performance is reflected in the failure analysis, and a means of evaluating the effect of maintenance on improving performance is provided. Using this procedure the significant contributors to performance can be identified, the value of different maintenance programs determined, and an optimum maintenance program defined.
