Abstract: (Max+) linear systems can be used to model a certain class of queueing networks. In their 1997 paper Baccelli, Hasenfuss and Schmidt have obtained an explicit expression for the expected value of the waiting time that the $n$th customer spends in a given subarea of such a system. Following similar analysis, we first generalize this result to higher moments and Laplace transform of transient waiting times in (max,+) linear systems with Poisson input. Furthermore, we develop a finite series expansion for the moments and the Laplace transform of stationary waiting times in (max,+) linear systems with deterministic service (firing) times. Examples pertaining to queueing theory are given to illustrate the results. This is joint work with Dong-Won Seo.
