Productivity gains in the manufacturing sector have generally been
credited to investments in production facilities that supplemented or
replaced manual labor. Insertion of circuit boards is a key activity in
the electronics industry. Improvements in productivity of circuit board
manufacture may be achieved by replacing manual component insertion with
automatic...
Background: The uneven distribution of recombination across the length of chromosomes results in inaccurate estimates of genetic to physical distances. In wheat (Triticum aestivum L.) chromosome 3B, it has been estimated that 90% of the cross over events occur in distal sub-telomeric regions representing 40% of the chromosome. Radiation hybrid...
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...
A multistage production system consists of a number of
production stages that are interrelated, that is the output
from one stage forms input to the next stage. There are
constraints associated with each stage as well as constraints
imposed by the overall system. Besides, there are multiple
objectives that need...
In February 1994, EPA proposed to "refine" its carbon monoxide (CO) hot spot model,
CAL3QHC, to increase its accuracy and reliability. Currently, this proposal includes
using hourly meteorological data recorded at airports near the modeling sites instead of
the worst case conditions now recommended as a modeling default. The analysis...
The fish processing industry is the most important
industry in Iceland. The single most important
processing method is quickfreezing, and the major market
is in the United States. With increasing competition in
the market from countries like Canada, productivity of
fish processing plants is becoming increasingly
important.
This research focuses...
The objective of many steady-state simulations is to
study the behavior of a nonterminating system with a peak load
of infinite duration. Due to the complexity of the system, the
initial conditions of the system are often atypical that often
requires the simulators to start the system with the empty...
Public construction projects are frequently presented as
occurring in complex social, political and economic settings
described as being uncertain. In public administration, this
uncertainty is cited as a cause for shifting from the so
called "rational-comprehensive" model of policy and decision
making toward an "incremental" or "mixed-scanning" approach.
None of...
An experimental investigation of factors effecting
scheduling a system of parallel, non-identical processors
using a series of experimental designs was carried out.
System variables included were processor capacities
relationships, sequencing and assignment rules, job size, and
product demand distributions. The effect of the variables was
measured by comparing mean flow...
A decision support system (DSS) for nurse scheduling in
hospitals is developed and implemented on microcomputer. The
system includes algorithms and databases for developing weekly
work and shift patterns and combining these into working
schedules for nurses for a specified time horizon, and
interface modules for the user to interact...
