Integrated monitoring, control and security of Critical Infrastructure Systems

Optimised allocation of actuators for DWDS

“…The chromosome is composed of real coded genes. One gene for each reservoir plus additional variables resulting from 24h long horizon with 1h time step (see [2]) for every allocated booster station.…”

“…It is assumed, that the water quality control algorithm, presented in the Definition 2 works in a hierarchical control structure [2], where the quantity (hydraulics) controller is already in place, generating appropriate flows and pressures in the network.…”

“…Therefore an adequate control strategy, suitable for wide range of operational conditions [2], including normal, disturbed and emergency operational states is required. Likewise as in most large scale and complex systems, allocation of control handles (actuators), namely disinfectant booster stations, becomes crucial for ensuring system sustainable operation.…”

“…Although, the uncertainty is neglected and the loop has no contribution to the results whatsoever it has been embedded into the algorithm to test its numerical efficiency. Incorporating uncertainty into the joint allocation task algorithm will most definitely require something more then the simple information feedback loop, namely Robustly Feasible MPC (RFMPC) [2,[16][17][18][19]31] which is known to be more computationally demanding. Therefore, testing efficiency of MPC algorithm at this point in the hierarchical optimisation framework validates is the approach potent to handle more demanding algorithms as well.…”

Load-balanced Integrated Information Security Monitoring System

“…As they are incompatible with each other and cannot provide output data in a single, chosen arbitrarily, format, it necessary to convert their output into a chosen scheme, as is usually done in numerous research projects aimed at some specific part or type of the system, e.g. [3], [9], [25], [27]. To address that problem, a general solution of data scheme conversion, based on the meaning of individual data fields, was proposed in [14].…”
