Planning systems targeted at such industries could well be build by using agent technology, and dynamic systems (control) structures;utilizing measurement and reaction mechanisms to derive to smart decisions.[We] believe that smart local decision making,making the right decisions at the right moment and right place are likelytoresult in well behaving planning systems.Feedbackplaysan important role in such systems.Performance measurement should not only look at the parameter as such,but also at the way those parameters change (and behave) over time –thus be aware ofthe first or second derivative of the function as well.
