In this paper a software package offering a means of simulating
complex water distribution systems is described. It has been
developed in the course of our investigations into the applicability
of neural networks and fuzzy systems for the implementation of
decision support systems in operational control of industrial
processes with case-studies taken from the water industry.
Examples of how the simulation package have been used in a
design and testing of the algorithms for state estimation,
confidence limit analysis and fault detection are presented.
Arguments for using a suitable graphical visualization techniques
in solving problems like meter placement or leakage diagnosis are
also given and supported by a set of examples
