Sage grouse are a species of concern because their abundance, distribution, and productivity have declined during the past century. Sage grouse productivity has been linked to specific habitat components including particular forbs and native bunchgrasses. Studies on the effects of fire were conducted in Southeastern Oregon in mountain big sagebrush...
ANSI/ASQC Z1.4 is a widely used attributes
acceptance sampling system. A necessary aspect of a
scheme, from both a theoretical and psychological
viewpoint, is the switching between normal, tightened,
and reduced inspection as a function of quality
history. In the latest revision of the standard the
switching rules were altered...
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...
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...
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...
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...
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 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...
A dynamic approach to the Bayesian theory of sampling inspection
by attributes for the single sampling case is presented. A model is
developed which assumes a sequence of lots of equal known size and
lots generated by a process operating in a random manner. The model
also assumes constant associated...
The goal of this study is to test the accuracy of
various mutual fund timing and selectivity models under a
range of portfolio managerial skills and varying market
conditions. Portfolio returns in a variety of skill
environments are generated using a simulation procedure. The
generated portfolio returns are based on...
