Q: Still on the Queuing Model, during my 7 days evaluation I notice that sometimes the value of Average Waiting Time per Customer turns out to be negative. What does the negative values means? How about positive values?
A: A negative Average Waiting Time per Customer indicates that the Arrival rate exceeds the Capacity of the service ie you need more service points. If the Average Customer Arrival Rate is greater than the Service Rate Capacity per Service Pt * the Number of Service Points then even without allowing for arrival distribution the Service Capacity is too low. When the Service Capacity is able to manage the Customer Arrival rate the Average Waiting Time per Customer is positive and this is how long on average a customer will wait for service.
