A method for minimizing a deviation of a physical parameter of a blow-molded container from a target value comprises determining a physical parameter of a container assigned to a machine parameter value of a blow molding machine and an environmental condition, based on the physical parameter and the target value, determining a change in the machine parameter, based on an iteration process, determining an optimal machine parameter value for achieving a minimum deviation from the target value of the physical parameter of a blow-molded container, the iteration process comprising a first iteration step for determining a deviation from the target value of the physical parameter of a blow-molded container based on a change in the machine parameter value, and a second iteration step for determining an adjusted change in the machine parameter value based on the deviation of the physical parameter of a blow-molded container from the target value.
