What are the differences between decision variables and uncontrolled variables? Describe the differences and provide an example from a simulation model

What will be an ideal response?

A decision variable is one that is under control of the decision maker and will change from one simulation run to the next as different events are simulated. Uncontrolled variables are random events that the decision maker cannot control. Both are functions of random numbers in the simulation model, but the decision maker realizes that the uncontrolled variables, such as weather, customer arrival patterns, state of the economy, and so on are outside his influence. Examples will vary.
