The document discusses maintenance engineering and its objectives. Maintenance engineering aims to optimize equipment, procedures, and budgets to improve maintainability, reliability, and availability. Its key objectives are to maximize equipment performance, prevent failures and breakdowns, increase system reliability, minimize interruptions, and prevent safety hazards. Maintainability, reliability, availability, and supportability are important factors that maintenance engineering considers and aims to improve through preventive and corrective maintenance practices. The product life cycle involves four phases - concept development, validation, production, and operation - that maintenance engineering and maintainability influence.
