Two parallel queues created by arrivals with two demands. I. (English) Zbl 0554.90041
At a queueing system customers arrive in a Poisson process at a unit rate. Each customer places two demands, which are handled independently by two servers, the service times having exponential densities with parameters \(\alpha\), \(\beta\), where \(1<\alpha \leq \beta\). The authors investigate the equilibrium probability of the numbers of demands of the two types waiting or being served.
