Remaining competitive in today's global economy means delivering higher quality
services and products at better prices. Your customers (and your bottom line)
demand continuous improvement http://www.thebravesprostore.com/Chipper-Jones-braves-jersey/ ,
lower costs and shorter delivery times. To ignore these realities will almost
certainly result in reduced profitability, or worse.
?Almost a Crystal Ball?
The problem with change is that it is risky; without
the proverbial crystal ball, we cannot be certain what to change, or what to
change to. There is, however http://www.thebravesprostore.com/Bud-Norris-braves-jersey/ ,
a way to evaluate the risks before implementing change, so reducing them to well
understood levels. Simulation can show you all possible outcomes in your
situation - and tell you how likely they are to occur! What this means for you
-- the decision maker -- is that you finally have, if not perfect information,
the most complete picture possible. You will see what could happen, how likely
it is to happen http://www.thebravesprostore.com/Bobby-Cox-braves-jersey/ ,
and so be able to judge which risks to take and which ones to avoid. While
simulation can鎶?predict the future, it can help you to choose the best strategy
based on the available information before committing significant funds to the
process. That's not a bad start!
Why not use simulation to improve
performance measurement for better manufacturing management? Identify
bottlenecks, improve productivity, implement lean manufacturing or perform
theory of constraints. Using the latest simulation techniques will help you
tighten up your processes to meet stringent market demand and out-perform your
competition by using simulation to plan, model http://www.thebravesprostore.com/Bob-Uecker-braves-jersey/ ,
validate, and communicate better ways of getting the job done.
You can simulate just about anything, but as a general rule, if
you can draw a flowchart of your system then you can simulate it. What
simulation does is to recreate all of the important and relevant logical rules
that tell a system how to work, and how long to take at each stage. It's easy to
think of a simulation of a manufacturing process http://www.thebravesprostore.com/Babe-Ruth-braves-jersey/ ,
but you can apply the same logic to health care, call centres, project planning,
and any other system where a job or unit of work flows through a number of
The processes you'll gain most benefit from simulating are those
that involve change over time and randomness; for example a call centre. Nobody
can guess at exactly what time the next call will arrive, for how many rings the
caller is prepared to wait for an answer http://www.thebravesprostore.com/ ,
or how long they will wait in a queue listening to music or messages before
hanging up. Modelling complex dynamic systems like this effectively in any other
way simply isn鎶?practical.
Simulation provides a vehicle
for a discussion about all aspects of a process. Defining the rules and
collecting data force you to consider why elements work in a certain way, and
how they could work better. It also brings to the surface inconsistencies and
inefficiencies especially between different sections of a process that work
There are many process improvements you can make using
simulation: higher quality and efficiency from capital assets, better management
of inventory, higher return on assets; the list is endless. But some of these
improvements could be made without simulation, so the real question is 'Why use
simulation instead of another method?'
Simulation vs Real Life
Experimenting in real life is costly. It鎶?not
only the capital expenditure of hiring new staff or purchasing new
it鎶?the cost of the ramifications of these decisions. What if you fire three
staff and then find you can't cope with the workload and you loose customers?
The only cost with simulation is the software and the man hours to build the
In real life it鎶?really difficult to repeat
the exact circumstances again so you only get one chance to collect the results
and you can't test different ideas under exactly the same circumstances. So how
do you know which idea is really the best? With simulation you can test the same
system again and again with different inputs.
If you want to know
whether hiring another three doctors will reduce patient waiting lists over the
next two years you'll actually have to wait two years. With simulation you can
run two, ten or even one hundred years into the future in seconds. So you get
the answer now instead of when it鎶?too late to do anything about
Aside from the machine operations, companies also
have to deal with product changeovers, variability and unpredictable events such
as workforce absenteeism, material shortages or accidents. All of these affect
the productivity of a production line.
Test driving new
Because of the high cost of both inefficiencies and new
optimizing systems design and operation is critical to improving overall
productivity, customer service and the bottom line. Simulation lets you build up
your system and then test it; you can combine process simulation and
optimization to help demonstrate, predict and measure system performance; you
can find out where and why problems occur, (e.g. why a bottleneck builds up),
allowing you to identify areas for improvement http://www.thebravesprostore.com/Phil-Niekro-braves-jersey/ ,
test out new ideas and, most importantly understand how a system works without
taking any significant risks and before introducing changes to live
With graphical and animated packages you can
communicate your understanding and improvement ideas to others. You can
visualise how work flows through your system and see its dynamics in fast
forward time. You can actually watch bottlenecks building up and see what is
causing the problems.
Simulation is helping companies take the guesswork
