The economic aspects of quality control have received wide concern since its developmental stages, however, they have not been sufficiently explored. Moreover, as the need for complex products of high precision and reliability increases, most industrial firms have experienced some difficulties in meeting that need at reasonable costs with their...
A comparison of two procedures which allocate inspection effort
within a production sequence is presented here. The concern
for quality and the need to hold down the costs of quality has resulted
in mathematical models which locate inspection so that the
desired quality is attained at a minimum cost.
In...
The purpose of this paper is to provide, at a basic level,
product layouts for an order picking warehouse that will minimize
average order picking time. A statistical model is developed to
ensure that optimal results rather than just 'good' results are
obtained. It is shown that simple but general...
Plywood production scheduling for years has been
considered, more or less, a sacred activity in which only
a select group of individuals with the experience and
knowledge could take part. With the advancements in
computer technology and related fields, the plywood
industry is in a position where more people can...
Much has been written concerning the determination
of a single sampling plan given two points on the operating characteristic (OC) curve. A computer program is
presented which will provide minimum sample size for
single sample attribute sampling plans. The program
provides sampling plans based on the binomial distribution. It incorporates...
The objective of this research was to investigate
the physiological effects of body posture on cycling.
The familiar positions of bicycle riding have been the
touring posture (hands stretched on top handlebar) and
the racing posture (hands bent at the elbow, with the
back horizontal). However, a relatively new stance...
The necessity for the evaluation of training methods on a between
methods basis is suggested. Current methods of training evaluations
are considered, and found to be generally deficient for their
lack of between technique comparisons. The necessity for an outline
of planned comparative analysis of training methods is indicated and...
A computer simulation was developed as a technique for
studying the effects of the process dynamics on the operator's
sampling and control behavior. This methodology was
used to study the effects of the process input memory
variation in the presence of different observation noise
levels. It was concluded that the...
With increasing frequency man is required to operate as a
controller of complex processes. Although his ability to operate
quickly varying processes has been extensively studied, his ability
to control slowly varying processes has been largely neglected.
Often his performance in such tasks is dependent upon his ability
to forecast...
There are a nearly unlimited number of situations in which the
status of time-varying processes must be updated. The monitoring of
these processes usually occurs at periodic intervals. Whether the
monitoring is performed by man or machine, a decision must be made
regarding the frequency of these activities, that is,...
