Kilgore Flares
Kilgore Flares,
is one of four operating companies in ATK’s
Conventional Munitions Group. It designs and
produces small, medium, and large caliber
ammunition, munitions propellants, commercial
gunpowder, infrared decoy flares, munitions
primers and tracers. Based in the United States,
Kilgore is the largest supplier of conventional
IR decoys to the U.S. Department of Defense.
Kilgore uses advanced conveyor control to
build flares of different sizes and
specifications. Using full automation,
pyrotechnic material is mixed and conveyed in
discrete quantities to the processing segment of
the facility where the material is pressed or
extruded into a final configuration. With a
single product line, optimization scenarios are
simple and can be implemented quickly. However,
with multiple product requirements shared on the
same line, optimizing throughput is
significantly more complex and critical to the
operation. In addition, faced with some normal
equipment failures and changes in the downtime
and recovery operation, it became apparent that
simulation software was required to capture the
intricate details of the model.
To perform the optimization analysis,
Kilgore engineers used CreateASoft’s
Simcad Pro
process simulation
and modeling software to create a virtual
replica of the existing line.
Simcad Pro
can
simplify the creation and implementation of
conveyors and conveyor interfaces, which helped
reduce the time required to build the model. To
expedite what-if scenario studies,
Simcad Pro
’s
real-time analysis tool provided immediate
feedback on the status of each process and parts
within the operation. The model allowed Kilgore
to apply ideas that optimize the line without
disrupting the operation. Different scenarios
and variables were tested (some dynamically) to
help achieve an optimal solution that increases
the line throughput based on product mixes.
"By varying parameters such as number of discrete quantities of material, size, and number of material carriers, conveyor speed, and product
rotation, we can determine a theoretical maximum
process throughput per day. Additionally, by
including MTBF, downtime, and recovery time, we
can determine a higher resolution process
capability."
-- R. Doyle of Kilgore.
With a complete and optimized simulation model,
Simcad Pro
can be used as a forecasting tool. By
loading WIP levels and forecasted product
requirements,
Simcad Pro
can detect issues that may
arise. As a forecasting tool,
Simcad Pro
aids
production management to maintain line optimization
regardless of the changes in order rate, product
mix, and machine downtime.
Simcad Pro
allowed Kilgore to achieve optimized
production and throughput on the line while
maintaining multiple product capabilities. Moreover,
Simcad Pro
’s ease of use was crucial for Kilgore to
build and analyze models quickly then convey the
changes to its production workers.
"Not only did it allow [them] … to consider alternative processes quickly, but the animation allowed people on the assembly line to see their operation in action and
understand the timing of the whole process."
-- says Doyle.
Simcad Pro
has
helped process-oriented users maximize productivity and
control costs across every industry. Created by
efficiency engineering experts, it makes a small but
powerful replica of a business that behaves like a
real-world model. Combining advanced data analysis,
virtual modeling, and the best in simulation technology,
Simcad Pro
delivers detailed statistical results of
every operation within the model. And while traditional
process simulation software focuses on the plant floor,
Simcad Pro
can be scaled to improve efficiencies in
every part of the enterprise. An open architecture and
intuitive user interface make
Simcad Pro
the ideal
process re-engineering and optimization tool for the
finance department, customer call centers, factory
floors, assembly lines, or any other business unit
comprised of complex, recurring processes and outputs.
Patented NO Coding Enviroment,
By using a set of predefined process types and
behaviors, building the model is quick and easy.
Simcad Pro
also includes cell creation and detail hiding. A cell, which
can contain multiple processes with other cells nested
within it, can be copied, pasted, or shared among models.
Model flow animation allows users to visualize bottlenecks
and resource contentions in two and three dimensions.
