A simulation model is used to test the impact of the number of sample customers at a supermarket. As the model is run the decision maker watches the average number of customers in the store rapidly increase from zero until it levels off and holds a constant value. The simulation model is: a. not valid due to the lack of change. b. in steady state c. not valid due to the fluctuation in the statistics. d. a random variable.

b. in steady state

Explanation:

As we know that the simulation model should be applied at the time when the number of samples with respect to the customers should be tested. Also it considered for the decision making purpose that shows the average no of customers that instantly increased from the 0 unit in the case when the level is off and also hold the same value. So here the simulation model should be considered as in the steady rate

Therefore the option b is correct

previous business sales - c.
