Basic Principles of Industrial Simulation
Steps for made a simulation study
Meet the system
The information is often not in a format and presentation for simulation since it is in accordance with the needs of the company.
Create a model
Integration of information obtained from data analysis.
Decide the scenarios
Optimistic
Intermediate
Pessimistic
After validating the model it is It is necessary to agree with the client the scenarios to be analyzed.
Validate the model
We have to make a process validation of model, where we will make a test series with real information for watch the behaviour and analyze the data
Keep Record Model, suggestions and conclusions
This documentation is very important, as it will allow the use of the model generated in case future adjustments are required.
Make a base simulation
First challenge for the simulation programmer.
Data gathering and analysis
Establish what information is useful for determining the probability distributions associated with each of the random variables.
Verify the model
Perform a data verification process to verify the property of the programming and the parameters of the model.
Analysis of sensibility
It is important to carry out statistical tests that allow comparing the scenarios with the best results.
Generate final model
Perform a data verification process to verify the property of the programming and the parameters of the model.
Elements to guarantee succes in a simulation model
Stable state of the variables
When a model has more than one decision variable, it is difficult for them to be in a stable state at the same time.
Select the variable correct
Even though the simulation model is very efficient, if the response variable is not appropriate, it will be impossible to make decisions about the operation system.
Relate correctly random variables
Forgetting or minimizing the impact of the logical relationships that exist between the random variables of the model.
Select the type of distribution suitable
Distributions that respond only to an attempt to simplify statistical studies.
Have a statistical study
Generating different final results for the variables, within confidence intervals, to find the final values.
Interpret of correct form the information
The information is often not in a format and presentation for simulation since it is in accordance with the needs of the company.
