A GI/G/1 queue is a queuing system with a single server and infinite capacity. Jobs arrive according to a renewal process with a given interarrival distribution having mean λ^(-1) and service times are i.i.d. with mean μ^(-1). The traffic intensity is defined as ρ=λ/μ, which is a natural measure of the load on the system. It is well known that the queue length process is ergodic only if ρ < 1. It is also known that when ρ < 1, the queue length is typically larger when there is more variability in the interarrival and/or the service time distributionsComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Probabilidade e Estatística
