The student attending this course should: • Comprehend the significance of failures from the technical and economic aspects; • Comprehend the issue of establishing a diagnostic of machine condition and monitoring programme; • Increase the availability and productivity of the equipment through a clearly defined technical strategy and to make competent decisions on it.

On the basis of mastered knowledge the student is qualified to: • Describes and distinguishes types of failures (casual, permanent, partial, immediate and gradual failure) and diagnosis techniques in the construction and maintenance of mechanical systems; • Describes and distinguishes different types of maintenance, with its advantages and disadvantages; • Applies proactive maintenance, using benchmarking and roadmaps to excellence; • Assesses the importance of failure and analyze maintenance costs; • Make a fault tree, i.e. perform FMEA and Pareto analysis of machine elements and systems; • Define the necessary parameters and procedures that allow failures monitoring and contribute to the contemporary maintenance procedure of machinery and equipment, and special tribological systems and mechanisms.

The role, objectives and techniques of failure analysis and condition-diagnostics in the construction and maintenance of mechanical systems (casual, permanent, partial, immediate and gradual failure). Failure analysis. The role of diagnostics and failure analysis in the maintenance of mechanical systems. Types of maintenance. Proactive maintenance. Benchmarking and road-map to excellence. Failures and analysis of maintenance costs. Management and technical strategy. Fault tree, FMEA analysis, Pareto analysis, etc. Types of failures in machine elements and systems. Failures case studies. Algorithms for the selection of monitoring methods. Analysis of results and corrective measures.
