Simulation Introduction

is a representation of the construction and working of

some system of interest.

• Simulation

• Modeling

• Validaton

• Event

is the operation of a model of

the system. The model can be reconfigured and

experimented with; usually, this is impossible, too

expensive or impractical to do in the system it represents.

• Simulation

• Event

• System

Enumerate problems

with an existing system. Produce requirements for a

proposed system.

• Stp - 01 Identify the problem

• Stp 02 - Formulate the problem

• Stp 03 - Collect and process real system data

• Stp 04 - Formulate and develop a model

• Sto 05 - Validate The model

Identify sources of

randomness in the system, i.e., the stochastic input

variables. Select an appropriate input probability

distribution for each stochastic input variable and

estimate corresponding parameter(s).

• Stp - 01 Identify the problem

• Stp 02 - Formulate the problem

• Stp 03 - Collect and process real system data

• Stp 04 - Formulate and develop a model

• Sto 05 - Validate The model

Define overall objective of the study and a few

specific issues to be addressed. Define performance

measures - quantitative criteria on the basis of which

different system configurations will be compared and

ranked.

• Stp - 01 Identify the problem

• Stp 02 - Formulate the problem

• Stp 03 - Collect and process real system data

• Stp 04 - Formulate and develop a model

• Sto 05 - Validate The model

Compare the model's

performance under known conditions with the

performance of the real system.

• Stp - 01 Identify the problem

• Stp 02 - Formulate the problem

• Stp 03 - Collect and process real system data

• Stp 04 - Formulate and develop a model

• Sto 05 - Validate The model

Translate these

conceptual models to simulation software acceptable

form. Verify that the simulation model executes as

intended.

• Stp - 01 Identify the problem

• Stp 02 - Formulate the problem

• Stp 03 - Collect and process real system data

• Stp 04 - Formulate and develop a model

• Sto 05 - Validate The model

Select a performance measure, a few input variables that

are likely to influence it, and the levels of each input

variable

• Stp 06 - Document model for future use.

• Stp 07 - Select appropriate experimental design.

• Stp - 08 Establish experimental conditions for runs.

• Stp 09 - Perform simulation runs.

Address the question of obtaining accurate information

and the most information from each run.

• Stp 06 - Document model for future use.

• Stp 07 - Select appropriate experimental design.

• Stp - 08 Establish experimental conditions for runs.

• Stp 09 - Perform simulation runs.

Runs were

performed as specified in Step 8 above.

• Stp 06 - Document model for future use.

• Stp 07 - Select appropriate experimental design.

• Stp - 08 Establish experimental conditions for runs.

• Stp 09 - Perform simulation runs.
