Complex Technical Systems Operation, Reliability, Availability, Safety and Cost Optimization

Abstract

The methods based on the results of the joint model linking a semi-Markov modeling of the system operation processes with a multistate approach to system reliability and safety and the linear programming are proposed to complex technical systems at the variable operating conditions, reliability, availability and safety optimization and cost analysis. The method of optimization of the complex technical systems operation processes determining the optimal values of limit transient probabilities at the system operation states that maximize the system lifetimes in the reliability or safety state subsets is proposed. The way of operation cost analysis of the complex technical system at the variable operating conditions and its application to the evaluation of the cost before and after this system operation process optimization is presented. The methods of corrective and preventive maintenance policy maximizing the availability and minimizing the renovation cost of the complex technical systems at the variable operating conditions are presented as well. The proposed methods are applied to the operation, reliability and availability optimization and operation cost analysis of the exemplary technical system and the port oil piping transportation system and to the operation and safety optimization of the maritime ferry technical system related to varying in time their operation processes, structures and components reliability and safety parameters. The procedures of the corrective and preventive maintenance policy optimization are proposed and applied to the exemplary system, the port oil piping transportation system and the ferry technical system.
