... ABSTRACT The aim of the paper is to describe the possibilities of using various modeling techniques, such as real time transient model, online look-ahead model and some offline calculations for operational planning. Short time horizon of one or two days is being considered for the planning...

... generated by end-users, can make it difficult to understand the dynamics of a network, particularly when using steady-state analysis, as it offers only a limited view of the system. This paper discusses how and why, a transient model of Dublin City was developed, and how the model was subsequently...

... would seem to indicate that a useful pipeline flow model should be a transient model, that is, it should solve the time-dependent flow equations. However, steady-state models are widely used to design pipelines, and to estimate the flow and line pack. Succession-of-steady-states (SSS) solutions...

... presents the estimates of performance obtained from preliminary studies. The project's main goal was to provide reliable and accurate leak detection at low cost. That meant providing better accuracy than a simple volume balance at a cost considerably less than a transient model based leak detection system...
