Each of an organization’s many activities transforms inputs into outputs. Managing these activities involves allocating input resources for some activities and assigning output targets for others. Making these decisions is especially difficult in the presence of uncertainty. In practice, many...

We propose a new procedure for providing confidence-interval estimators of the mean of a covariance-stationary process. The procedure, a modification of the method of batch means, is an improvement over existing methods when the process displays strong correlation and a comparatively small...

An event takes place at time t, a discrete random variable with known probability function. At unit intervals of time, a measurement x is observed which yields information about the event; x is a random variable, with a known probability density function being dependent upon whether or not the...

We address an assembly problem, motivated by flat panel display manufacturing, where the quality (or performance) of the final product depends upon characteristics of the components to be assembled, which are not constant from component to component. We analyze the tradeoff between the increase...

A new structure for economically-based sequential inspection plans is developed for use in motor vehicle emission testing. The structure allows for multiple attributes, multiple sources of randomness, misclassification of inspected items, and adjustment of cost parameters to produce desirable...

This paper expounds some of the results of Fourier theory that are essential to the statistical analysis of time series. It employs the algebra of circulant matrices to expose the structure of the discrete Fourier transform and to elucidate the filtering operations that may be applied to finite...

Whenever the specification of a dynamic regression relationship is in doubt, we should think of adopting a rational transfer-function model with separate parameters in the systematic part and the disturbance part. Some of the models which are commonly used in applied econometrics can give rise...
