The Productivity of Machines Requiring Attention at Random Intervals
随机间隔需要照管的机器的生产率
Summary In many industrial processes an operative attends a number of machines which stop from time to time. Each time a machine stops the operative has to do a certain amount of work before it can be restarted. If at any time two or more machines are stopped simultaneously, there will be a loss of production due to the period the machines have to wait for attention. In this paper we derive methods of estimating this loss of production when the operative has no duties away…
