We wish to estimate the variance of the sample mean from a continuous-time stationary stochastic process. This article expands on the results of a technical note (Goldsman and Schruben 1990) by using the theory of standardized time series to investigate weighted generalizations of Schruben's...

Asymptotic confidence interval estimators of the variance parameter \sigma ² = lim_{n - \infty} n Var((1/n) \sum ⁿ_{i = 1} X_i) are described in this paper for observations X₁, X₂,...,X_n from a strictly stationary phi-mixing stochastic process. They are based on asymptotic properties of the...

A case study of the analysis of operator reponse times following an abnormal event is presented. A number of timings of operator responses on a full‐scale nuclear plant simulator have been taken. These timings are compared with the human cognitive reliability (HCR) model. Agreement with the...

The duration between product design and its successful introduction into the market, also called “Time to Market”, emerges along with cost and quality as one of the crucial factors that decide competition. Considering this trend, several strategies and tools together with examples for a...

Much management training is still conducted by faith rather than on a cost‐benefit basis. The use of simulated management environments is proposed. This can be implemented at the workplace, not just on a training course. Examples of benefits from an actual case are given.

The development of communication skills is increasingly a key element in the training of staff who have a regular contact with the public. The Glasgow Garden Festival took place over the summer of 1988. For the purposes of staffing the information centre, the Inverclyde Initiative chose to...
