of this simulation to obtain important parameters of a bank queue‚ including bank information‚ queue length‚ waiting time in queue and expected wait time of customers in a bank. To obtain the appropriate function for predicting the queue waiting time we need a large numbers of observations. To obtain this data without the need to collect them directly‚ we simulate the bank work flow and after ensuring that the model built reflects the actual situation‚ we use the output data and simulations for prediction
