Solve this problem –
A bank is contemplating whether to use 5 tellers and 1 line
(Process Logic A) or 5 separate lines, one line for each teller
(Process Logic B)
Customers arrive into the bank at the interarrival time that is exponentially distributed and a mean of 1 minute. (EXPO-1)
2a. Case 1: when each customer requires a processing delay of
TRIA(3,5,7). Compare the performance of the two process logics given
above.
2b: Case 2: when each customer requires a processing delay of
TRIA(3,5,12). Compare the performance of the two process logics given
above.
Run the simulation for 2 hours.
Note: To spilt entities into one of the 5 lines, use decision
(n-way by chance) block – use 20%, 20%, 20%, 20%, — else block to
split the traffic into 5 lines.
