• MAINTENANCE MANAGEMENT

  • Maintenance policies and types: financial objectives. Maintenance cost versus failure cost. Different types of maintenance and respective importance: systematic preventive, condition-based, predictive, corrective. Preventive maintenance tools, measurement, follow-up and reliability engineering (fault tree, Pareto, identification of the “bad actors”). Methods and current trends: criticality analysis, Japanese and American methods, risk analysis-based decisions. Studied methods application: criticality rankings, levels of emergency, stocks of spare parts. Outsourcing and subcontracting, shutdown management, improvement plans.

• PROJECT: MAINTENANCE ENGINEERING - JURY

  • During the final project, participants will work as teams and develop a project related to the maintenance, the energizing, the functioning of the support, the management of a machine overhaul, a manufacturer brief… This 10-day project is based on existing data. Participants are coached all along the project to help them reach the objectives set: writing a report and presentation to a jury of personnel from the company and IFP Training.
