In designing experiments to find the unknown variables, various conditions of the oven works each season by using a mathematical model of an incubator can save energy to use.
In designing an experiment to find the unknown variable values. Used for the working conditions of the oven each season, using a mathematical model of the oven so that the energy can be used in baking.
In the design of experiment to find the unknown variable values Used to working conditions of the oven in each season by using the mathematical model of the oven to save energy in the steam.
