decisions that have been explored and proven in detail.

Scope

The Six Sigma philosophy covers different aspects of industrial processes ranging from pure defect to process performance improvement. With the increasing use of Six Sigma methodologies, it has become widely accepted that process simulation and modeling techniques can be used for improving almost any type of manufacturing or transactional process. Most of the process simulation and modeling techniques are based on DMAIC (Define, Measure, Analyze, Improve, Control). In the 'Define' phase, the process simulation techniques are used for identifying the changes that would have made the most impact on the outcome. This helps in making the most appropriate changes. Various simulation tools are used throughout the other phases for providing detailed statistical data on the effect of any proposed changes related to throughput, utilization, delays, service levels, and any other factors related to the process.

How The Simulation Model Works

-The simulation software coverts numerical data into graphic representations, which are relatively easier to understand.
-Commercial companies that specialize in providing Six Sigma services offer customized services, wherein the simulation model is an exact replica including all the elements used in the actual process such as machines, labor, conveyor and belts.
-All these elements are represented by icons and once they are in place, one can define the link between these elements, establish the process flow, and add as much detail as possible for simulating the actual process more accurately and more effectively.
-After setting up the simulation, one can simulate an infinite number of hypothetical scenarios both positive and negative that might affect the process. For example with the help of simulation, a manager can know exactly what will happen if a crucial machining tool breaks down or half the labor force does not turn up for work.
-All these factors can severely affect production. However if the extent of potential damage is known beforehand, appropriate contingency plans can be put in place for restricting or even eliminating the possible loss of production.

Process simulation and modeling techniques help executives make informed decisions. The data generated by the simulation tools empowers decision makers with a deep insight about the process and procedures, allowing them the ability to make the necessary changes.
