28 New DSS: Comparison old with new system Actual DSS Pumping station control automated, based on historic defined rules New Version with RTC-tools 2 Better and more extensive control: Pumping station control automated, based on multiple control goals Water security (water level) prevails The goals are: Flushing the system based on water quality goals for different customers Minimization of wind effects Energy efficient control of pumping stations Anticipatory water level management to prevent damage caused by flooding Use of emergency storage areas / Stop of pumping stations / Compartmentation For storage basin and also for 5 polder systems

33 New DSS: Conclusions Defining new functionality in early stage is big win during realisation Involvement of future users during whole process is key success factor Realisation with defined sprints makes realisation clear Determine user wishes as must haves and should haves to go-live RTC-tools 2 gives possibility to optimize on multiple goals Challenge is to make the solution path insightful and understandable to the end-user Expert judgement is replaced by expert systems Experts with knowledge and understanding of water level management/ models/optimization modules remain necessary Small margins, many goals: Challenge to be solved with RTC-tools 2
