WebOct 15, 2014 · Last updated: October 15, 2014 Perry Klukin. Studies have proven that a single-line queue leading to multiple servers is more efficient and results in less variation in the amount of time customers are kept waiting. Still, the single-line queue can appear daunting to customers who fail to understand that one longer line is actually a better bet ... Webnetworked servers. In a recent work we have provided an approximate solution for the response time distribution of the MMPP/M/1 queue, which is based on a weighted superposition of M/M/1 queues (i.e. a hyper-exponential process). In this article we address the tradeoﬀ between the accuracy of this approximation and its computational cost.
