Multiple dispatches in a poisson process

An optimal policy is characterized for operating the following system. Customers arrive in [O, T] according to a homogeneous Poisson process. Instantaneous services are provided at times O and T. Additional instantaneous services can be provided at N intermediate stop ping times. These times must be chosen to minimize the total expected customer-hours in [O, T] spent waiting for service.     

Derivation and application of unit cost expressions perturbed by design changes

Learning curves have been used extensively to predict future costs in the airframe and other industries. This paper deals with the effect of perturbations induced by design changes on the learning curves. Equations that are developed and applied make it possible to predict future costs accurately in a perturbed environment. The formulations can be used effectively in EDP programs.     

New ANSI versions of MIL-STD-414 and MIL-STD-105D

When acceptance sampling plans are applied to measurement characteristics, a choice between application of a variables or an attributes sampling plan must be made. With the recent revision by the American Society for Quality Control for the American National Standards Institute of the ANSI/ASQC Z1.9 variables system and the ANSI/ASQC Z1.4 attributes system, the standards have now been matched so that it is possible to move between them. This article will discuss exploitation of the resulting synergistic relationship to achieve more rational and more effective acceptance sampling.     

Transshipment along a single road

This article explores the problem of the transshipment of goods between centers that are situated along a single road. Costs are incurred both for goods that are shipped and for goods that remain in their original centers. A procedure is developed that determines a partial optimal assignment by use of a northwest corner rule solution. This partial assignment then is completed by solving a number of smaller tridiagonal transportation problems.
