  • the server 300 corrects the change value of the target temperature corresponding to the evaluation for each evaluation item and evaluation period based on the user's evaluation tendency for each evaluation item and evaluation period (step S402). For example, the server 300 corrects each of the multiple change values of the target temperature corresponding to the evaluation for each puff timing set for multiple evaluation items based on the user's evaluation tendency for each evaluation item and puff timing.
  • the server 300 integrates the corrected change values of the target temperature for each evaluation period (step S404). For example, the server 300 calculates the final change value of the target temperature for each puff timing by integrating multiple corrected change values of the target temperature corresponding to the evaluations set for multiple evaluation items at overlapping puff timings.
  • the server 300 changes the heating profile based on the change value of the final target temperature for each evaluation period (step S406).

  • the server 300 may collect training data including information indicating the user's evaluation tendency.

For example, in the example shown in Table 3, the server 300 may collect training data including heating profile P1 as the first heating profile, evaluation E1 corrected based on the user's evaluation tendency, and heating profile P100 as the second heating profile.
  • the server 300 may correct the change value corresponding to the user's evaluation in the same direction as the user's evaluation tendency. For example, if the user tends to evaluate the smoking taste as strong, the server 300 may correct the evaluation of the smoking taste more strongly.
  • this configuration it is possible to prevent the change range of the target temperature from being insufficient based on the user's modest evaluation. As a result, it is possible to prevent a situation in which the target temperature is changed only little by little and the heating profile as intended by the user is not easily reached.
