Tolerance analysis and synthesis plays a vital role in the success of a product design because it directly affects product quality and manufacturing cost. It also affects manufacturing process selection and planning. This research provides a review of several commonly used assembly tolerance analysis models and evaluation of their limitations....
Automated Storage and Retrieval (AS/R) Systems
have had a considerable impact on manufacturing and
distribution processes. The configuration of AS/R systems
vary considerably, depending on the particular application.
The effect of different retrieval scheduling rules
is analyzed and compared for three different unit-load
AS/R systems operating under dual-command cycle. The...
The focus of this research is to design and develop a microcomputer-based information management and production planning system for a discrete parts manufacturing facility. The information management module is based on relational database concepts. This information is used by the scheduling module to generate initial production schedules based on manufacturing...
The problem of resource planning has long been a topic of interest for operations managers in both production and service industries. Inputs such as raw materials, energy, and capital are limited resources; therefore, managers must make informed decisions regarding the use of these inputs. This thesis addresses the area of...
Expert systems have been suggested as a solution
for difficult problems, including FMS scheduling. As
one of the aspects of artificial intelligence (AI), expert
systems have achieved considerable success in recent
years in medical science, chemistry, and engineering.
However, building an expert system is a difficult
task, the most crucial...
Multiobjective Decision Making (MODM) has been
suggested for the solution of complicated decision
problems. Decision analysis in numerous areas, including
industrial energy and environmental planning, necessarily
requires consideration of multiple conflicting
objectives. MODM has been successfully applied to
a number of these problems of this type. Moreover, it
has the...
The objective of many simulations is to study the
steady-state behavior of a nonterminating system. The
initial conditions of the system are often atypical because
of the complexity of the system. Simulators often start
the simulation with the system empty and idle, and
truncate, or delete, some quantity of the...
A standardized color code is used to aid the driver in the prompt
recognition of highway signs. At night, these signs are illuminated by
various light sources including the headlights and other fixed light
sources. These light sources may distort the appearance of the colors
of the signs at night....
Machine Vision has been extensively applied in industry.
This thesis project, which originated with a local food
processor, applies a vision system to inspection of packages
for cosmetric errors. The basic elements and theory of the
machine vision system are introduced, and some image
processing techniques, such as histogram analysis,...
One of the commonly used simulation approaches is process orientation. This is based on the use of nodes (or blocks) that perform functions in series. In spite of the compactness and ease of learning that characterize process-based simulation, many languages are somewhat complex, primarily the result of the large number...
