- Abstract
- The replacement of aging plant and facility equipment is a major concern of all Federally-owned and operated installations. Past efforts at equipment replacement have often underutilized information on the service life distribution of a particular component/system. More specifically, equipment was usually maintained until it either failed or reached some average age at which time total replacement was initiated. This study develops a framework, based on service life distributions fitted to data from a published survey, for dealing with the "replacement problem." Service life distribution are used to develop replacement schedules for approximately 50 major pland and facility equipment items at the National Bureau of Standards (NBS) Gaithersburg and Boulder sites. The costs associated with these replacement schedules are estimated on an annual basis over a ten-year planning horizon using a probabilistic cost model. Estimates from this model are intended for use in budgeting for replacements over the planning horizon. The results of this study indicate that approximately $15 million (all estimates are in first quarter of 1980 dollars) will be needed to meet expected replacements during fiscal years 1982 through 1991 at the NBS Gaithersburg and Boulder sites.
