A very caf receives customers at a rate of 35 customers per hour. Currently the caf has 4 baristas each requires on average 5.5 minutes per customer. Assume inter-arrival and processing time are .exponentially distributed The system can be represented according to Kindall Lee notation as M/M/5.5/GD/35 is around 80% P For this system is accepted to be larger than 1 The probability the system is empty is equal to about 2% The average number of customers in the system is about 5.6 customers Increasing the number of workers to 5 would result in a traffic intensity of about 64% The probability the system has more than 3 customers is about 52% G The average waiting time in the queue is less than 2.14 minutes
