Using the formulas of queueing theory everyday waiting situation can be examined. As an example we present four typical pattern for discussion:
Short description of the individual systems:
This raises the question which is the best system in practice. To compare the systems we use as a the average number of customers in the system as the performance indicator.
The following parameters are assumed for comparison of the performance of the systems:
Arrival rate | ![]() |
Service rate | ![]() |
Coefficient of variation of the arrival process | cl = 1.0, |
coefficient of variation of the service process | cs = 0 |
