Maintenance is a necessary (and usually burdensome) function for practically all natural and man-made elements. Simply defined, maintenance is the effort to keep a device or system working. The amount of funding allocated for maintenance by an organization is necessarily a compromise, possibly viewed as too much by management and too little by the operators/maintainers. The objective of our study was to report on the wide range of costs involved in maintaining equipment. We discuss some methods that different industries use to measure and report their maintenance costs; we summarize the results of a literature search on the range of maintenance costs for several industries; and we report on our own study of maintenance costs in the National Aeronautics and Space Administration (NASA) Deep Space Network (DSN) and how these maintenance costs compare to the other reported results.
