1. A temperature control simulation method for simulating temperature control on a heating furnace equipped with a heater by using a temperature system simulation device, said method comprising:

  • determining transfer function means representative of a relationship between an input to said heater and a temperature of said heating furnace;

    simulating temperature control on said heating furnace by using said transfer function means as a transfer function means of said temperature system simulation device; and

    obtaining a temperature output as a temperature control result based on said input to said heater without using an actual furnace;

    wherein said transfer function means comprises a parameter which changes over time in accordance with a temperature control process, and wherein said temperature control process comprises a process of controlling a temperature of said heating furnace during a time when a boat is loaded into said heating furnace, and said parameter of said transfer function means which changes over time comprises a time constant.
