Study of the Causes of Man-Hour Variance of Naval Shipyard Work Standards (The National Shipbuilding Research Program).

摘要

This paper is a presentation of the results of a study conducted at a U.S. Navy shipyard during 1987 concerning the relationship between engineering standards and the variances that were occurring in production budget and charged manhours. The 10 engineering standards having the greatest manhour variances were examined. These standards, as a group, accounted for ahout 62 percent of the manhour variance that was reported during the first nine months of 1987. The study indicated that, with one exception, all of the standards were 'generic' in their application, i.e., they can be applied over a wide range of job orders. The study also concluded that engineered standards are only partially responsible for the production variance.
