摘要:

AbstractThe problem of consolidating certain sections of the allowance list is stated and discussed. A practical consolidation rule is proposed and illustrated by numerical examples. The validity of this consolidation rule is established for normally distributed demands, and its general usefulness is outlined.

摘要:

AbstractThis paper contains the text of a briefing on a method of estimating spare‐part “essentiality” or “shortage penalties.” The estimates are made by collecting and combining the judgments of individual maintenance specialists. While the talk was primarily directed to a military audience, the subject appears to be of general interest, since the problem of estimating shortage penalties must be faced in applying any of the optimal inventory policies which have been developed in recent years. The quantitative solution of many other management problems also requires input data which can only be obtained on the basis of expert

摘要:

AbstractExtensive work has been done in deriving the optimum inventory policy for various models based on different assumptions. The following is an attempt to find the cost consequences for two such models of executing a policy computed from erroneous data. Part I treats a case of certain demand. Part II treats a case of demand being a uniformly distributed random variable.

摘要:

AbstractThis paper discusses some queuing problems that arise in the context of the maintenance of a group of machines, each of which is operated intermittently and all of which are subject to several kinds of malfunctions. A general formulation of this problem is made and the general method of solution indicated. A class of solutions in form suitable for direct computations is given. As a special case, a solution is given to the case of mjrepairmen of type j, j = 1, …, k for a group of fully utilized machine
