A traditional System Dynamics Model is compared with an Anticipatory Soft Computing Approach. A system for control and management of water resources and hydro electrical power stations is used as a real world test case. The System Dynamics Model is easily developed and run with help of commercial, special purpose modelling and simulation software. The resulting model increases understanding and generates new insights. Its lack of anticipatory power, however, makes the control task difficult. With the anticipatory approach, on the other hand, the control becomes more effective even if the modelling and model complexity increases rapidly than applied on a reasonable big and realistic real world case. Strong Anticipation, as compared to the more traditional Weak Anticipation, has proved itself to have many interesting and powerful properties.
