METHODS FOR COMPENSATION OF UNCERTAINTIES IN ENSURING SAFETY OF COMPLEX TECHNICAL SYSTEMS AND OPTIMIZATION OF LIFE CYCLE COSTS
The paper addresses the problem of compensation of complex technical systems' uncertainties that are related to natural variability of systems' parameters and human errors. Such compensation can be achieved through introduction of safety factors and strengthening the strategy of technical system monitoring and maintenance. The procedure for the system life-cycle cost minimization is presented. This procedure involves the search of minimum of the surface of the system's life-cycle costs that are the functional of safety factors and the maintenance strategy.
