This article describes the problem of the initial transient that arises when estimating the limiting distribution of a nonterminating stochastic process. Concepts are explored with references to simple M/M/1 queueing model with an artificially induced initial bias. A range of solution methods have been proposed and here we explore two such approaches, graphical and heuristic. We also demonstrate how these methods might be combined. Results from test problems consistently show that truncation of output data from a single long run is more economical than the replication/deletion approach for nonterminating simulations.
