A System Dynamics Approach to Optimize Milk Production in an Industrial Ranch

The milk production process on an industrial ranch consists of various and regular activities, with each requiring a proper management approach. Different variables also affect the process, maximum is achieved by identifying critical variables. This work was motivated Fereidan Ahrar in Isfahan, Iran, which seeks to identify optimize important increase production. unit considers livestock omission due disease losses as one issues. kind followed increased medical costs ranch. paper investigated system dynamics approach Vensim software simulate considering combination demographic costs. System sensitivity analyzed using design experiment (DOE) technique some scenarios were proposed maximize tuning affecting simulation results designed model showed five These include cycle rate, voluntary change rates female calves per year that are entered into life ranch, pregnant heifers become dairy herds after calving, finally, effect
