The objective function specification is used as a measure for quality of the calibration. Measurements are not real but consist of output results of a previous MIKE SHE simulation. AutoCal evaluates objective functions by comparing dfs0 files therefore real observations should normally be used as target files.
AutoCal minimises an aggregation of one or more objective functions. Each objective function may consist of several so-called output measures. For the present example one objective function (MyFunc) is defined. MyFunc is specified as weighted sum and it is given a weight value of 1.
Well_01 and Well_02 are specified as output measures. Both measures are specified as the Avg. Error of the difference between the simulated SZ head elevation and the measured SZ head elevation in correspondence of the two pumping wells. By specifying the weight as 1 and the function name as MyFunc the measure will contribute to the objective function called MyFunc with a weight of 1.
No aggregation of objective functions is applied.
