Abstract : Cross sectional data from the U. S. Navy's Atlantic Fleet Destroyer Force is analyzed in a three-part study of relationships between a ship's total maintenance cost, time lost from operations, reliability, and the length of its overhaul cycle. Factors such as ship age, size, complexity, usage, etc., are held constant as required. The overhaul cycle is viewed as the primary control variable by which Navy maintenance managers allocate effort between scheduled and unscheduled repairs. A minimum cost overhaul cycle is obtained. In the absence of defensible cost penalties for time lost and reliability (where the latter is measured by the frequency of unscheduled repair), minimum cost and optimal cycles are not one and the same. Tradeoffs between cost and reliability are obtained, however, and the range within which an optimal cycle may be expected to lie is narrowed considerably. (Author)
