EXPERT CONTROL SYSTEM FOR INCREASE OF SAFETY OF SHIPPING OPERATION ON THE GABCIKOVO PROJECT ON THE DANUBE
Abstract
Task of shipping operations control of the Gab??kovo project (GAP) is to synchronise several requirements. These come from versatility of GAP and must meet following goals (maximization of the ship locks capacity, maximization of income from electricity production in hydropower plant, navigable depth below minimal shipping depths in ford sections caused by flow changes on GAP and ships crushing into riverbed of the Danube river). By taking these goals into account, we can, in general, define operation of GAP as complex multicriterial optimization task with many technological, water management, energetic and environmental constrains. Standard approach in solving this problem includes elaboration of optimization or simulation model of GAP operation. If mathematical description of problem does not exist, ?classic? expert control system management must be applied [1]. Based on above stated criteria, most effective approach to this problem appears to be creating software application, that combines both approaches. In this case, Expert control system of shipping operation on GAP (ECS) will be software application to model hydraulic links and hydraulic regimes (discharges, water levels and flow velocities) based on relevant inputs on the ship locks and whole section of the Danube river, that is affected by GAP operation. Model of shipping operation should be modelled to meet minimalization of ship?s delay while waiting to transit and minimalization of destruction parameters due to fast flowing water in the filling and emptying system and assuring the shipping safety by keeping parameters of river specially on ford sections of river on whole part of river affected by GAP. The paper describes architecture of proposed Expert control system and focuses mainly on analysing suitability of heuristic optimization methods for solving above the stated optimization problems.
