Water
Operational Research Centre at Brunel University
ACTUI
related research at Brunel University is carried out in the Water
Operational Research Centre (WORC) in the Department of Systems
Engineering . The centre has two full time academic staff, two full
time research staff, one PhD student and one Engineering Dept student. |
The
aim of WORC is to facilitate research endeavour into mathematical
modelling, control, optimisation and software design relevant to
large-scale water distribution systems.
Objectives:
|
Modelling |
To
develop accurate mathematical models of the hydraulic, chemical and
particulate behaviour of water in water distribution systems.
|
Monitoring |
To
develop methods for on-line monitoring of large-scale water distribution
systems (including automatic burst detection).
|
Control |
To
develop software based techniques that enable more efficient operational
control of large-scale water distribution systems, including strategic
control and pressure optimisation.
|
Forecasting |
To
enable accurate predictions of water consumption to be made through the
use of extended period simulations coupled to optimisation and demand
forecasting.
|
Enabling
Technologies |
To
investigate the use and applicability of mathematical programming methods,
artificial neural networks, genetic algorithms and other novel approaches.
|
Information
Technology |
To
provide a software framework, using relational and/or object-oriented
technologies, that facilitates open interaction with third-party
applications.
