Maintenance management involves keeping physical plant and equipment in good operating condition to minimize downtime and costs. The objectives of maintenance management are to minimize loss of productive time, repair time and costs, and total maintenance costs while maximizing quality, equipment uptime, and safety. Effective maintenance management includes preventive, predictive, routine, and planned maintenance approaches across civil, mechanical, and electrical systems. Proper control of maintenance involves authorization, scheduling, budgeting, and equipment records. Key considerations for maintenance include determining appropriate staffing and outsourcing levels as well as leveraging computer systems. High quality, reliable equipment can improve productivity if maintenance is considered early in the procurement process.
