| Abstract | The problem addressed is the computation of nodal and .system
expected unserved demand, unavailability and other reliability
indices of a water supply system having random demand, ground-level
I
clear water storage, unreliable pumps, and unreliable treatment
plant. An individual nodal demand model of two stage
(normal, emergency) Markov process is assumed. The failure of the
treatment plant is taken into consideration. A Markov Chain
Approach is employed to determine
·of the system states. It is
automatically controlled a nd the
the steady state probabilities
assumed that the pumps are
flow through the pipes are
regulated according to a real-time optimal policy which gives equal
importance to the flow quantity and pressure-head at individual
demand nodes. The above optimal pump-discharge and f 1 o w -
regulation policy can give priority for emergency demand and
critical nodes by assigning different shortage cost factors.
