E. Basic Steps and Decisions for Simulation [LR] The Basic Steps of a Simulation Study Show
Decisions for Simulating To recognize if simulation is the correct approach to solving a particular problem, four items should be evaluated before deciding to conduct the study:
Availability of Resources: People and time are the determining resources for conducting a simulation study. An experienced analyst is the most important resource since such a person has the ability and experience to determine both the model's appropriate level of detail and how to verify and validate the model. Without a trained simulator, the wrong model may be developed which produces unreliable results. Additionally, the allocation of time should not be so limited so as to force the simulator to take shortcuts in designing the model. The schedule should allow enough time for the implementation of any necessary changes and for verification and validation to take place if the results are to be meaningful. Costs: Cost considerations should be given for each step in the simulation process, purchasing simulation software if not already available, and computer resources. Obviously if these costs exceed the potential savings in altering the current system, then simulation should not be pursued. Availability of Data: The necessary data should be identified and located, and if the data does not exist, then the data should be collectible. If the data does not exist and cannot be collected, then continuing with the simulation study will eventually yield unreliable and useless results. The simulation output cannot be compared to the real system's performance, which is vital for verifying and validating the model. The basic steps and decisions for a simulation study are incorporated into a flowchart as shown below: Steps and Decisions for Conducting a Simulation Study Once simulation has been identified as the preferred approach to solving a particular problem, the decision to implement the course of action suggested by the simulation study's results does not necessarily signify the end of the study, as indicated in the flowchart above. The model may be maintained to check the system's response to variabilities experienced by the real system. However, the extent to which the model may be maintained largely depends on the model's flexibility and what questions the model was originally designed to address. Back to Table of Contents Which of the following is a benefit of using a simulation instead of an experiment?A simulation allows investigation of a phenomenon without the real-world limitations on time, safety, or budget. A simulation can be used to model real-world events that are impractical for experiments.
Which of the following best describes a limitation of using a simulation for this purpose?Which of the following best describes a limitation of using a simulation for this purpose? A The model used by the simulation software cannot be modified once the simulation has been used. Running a simulation requires more time to generate data from trials than observing the crowd exiting the arena at various events.
Which of the following are benefits of using well named variables in a computer program?Which of the following are benefits of well-named variables? -The program will be easier to read. -The program will be easier for others to debug.
What is the most appropriate data type for age?So, we should use integer data type for age.
