The Basics of Predictive/Preventive Maintenance
Overview:Traditional maintenance costs (i.e. labor and material) in the United States have escalated at a tremendous rate over the past several years. In 1981, domestic plants spent more than $600 billion to maintain their critical plant systems. By 1991, the costs had increased to more than $800 billion and topped $1.2 trillion in 2000. These evaluations indicate that between one third and one half of these maintenance dollars are wasted through ineffective maintenance management methods. The dominant reason for this ineffective use of maintenance expenditures is the lack of factual data that quantifies when and what kind of maintenance is needed to maintain, repair or replace critical machinery, equipment and systems within a plant or facility.
