A modelling scheme for simulation of queueing structures is proposed. After a general discussion about the special properties of queueing structures and how such usually are investigated, the scheme follows. The scheme makes use of three different concepts: Deterministic Analysis, Load Analysis and Balance Analysis. These concepts are explained and thereafter used in the modelling scheme. It is emphasised that complex models are difficult to handle and validate and that a simple model which comprises the important features of the "real" system is to prefer. The paper discusses which these features can be and how to find them.
