Change the objective

[jpfnunes]

Hi,

How can change/add a new performance index to minimize, as not only time but also the cost of machines per hour.

Thanks.

Hi jpfnunes,

If you want to create your own objective using cost, first you need to create a machine-cost data using 2D array or something. Then you should change the FitValue to TotalCost function instead of Makespan which is currently exist. To calculate the TotalCost, what you need is the total working time of each machines separately. So by multiplying the total time by the cost and summing the results, you get the TotalCost.

Hi aalitor,

is it possible to set a fixed starttime to some processes? I want to have real jobs and "free space jobs" that come from a calendar. So these spare/free/pause jobs are not allowed to be moved/optimized.

Thanks,
Boontog

Hi

The time has no specific unit. You can pretend it as what you want as long as they are entered in the same unit.

Hi aalitor,
Could you please help me with the mathematical model and how solved it by genetic algorithm?
