Next, in step S28, the response reliability determination unit 209 determines whether or not the response reliability calculated by the response reliability calculation unit 206 is lower than the adoption reference value. Here, when it is determined that the response reliability is lower than the adoption standard value (YES in step S28), in step S29, the questionnaire distribution control unit 205 provides the communication unit with the stop instruction information for stopping the presentation of the questionnaire information. The output is output to 201, and the communication unit 201 transmits the stop instruction information to the cooking device 10. After that, the process returns to step S22.

On the other hand, when it is determined that the answer reliability is equal to or higher than the adoption reference value (NO in step S28), in step S30, the answer remaining time calculation unit 208 has the answer reliability lower than the predetermined threshold value from the current time. Calculate the remaining answer time, which represents the time until the time.

Next, in step S31, the questionnaire distribution control unit 205 updates the remaining answer time currently displayed on the cooking device 10 to the remaining answer time calculated by the remaining answer time calculation unit 208. Is output to the communication unit 201, and the communication unit 201 transmits the update instruction information to the cooking device 10.

Next, in step S32, the questionnaire distribution control unit 205 determines whether or not the questionnaire response information transmitted by the cooking device 10 has been received. Here, if it is determined that the questionnaire response information has not been received (NO in step S32), the process returns to step S26.

On the other hand, when it is determined that the questionnaire response information has been received (YES in step S32), in step S33, the questionnaire distribution control unit 205 stores the received questionnaire response information in the questionnaire response storage unit 210. After that, the process returns to step S22.

Subsequently, the response reliability calculation process in step S26 of FIG. 5 will be described.

FIG. 6 is a flowchart for explaining the response reliability calculation process in step S26 of FIG.

First, in step S41, the response reliability calculation unit 206 calculates the elapsed time from the time when the cooking of the food is completed. The time when the cooking is completed may be included in the first cooking equipment log. Further, the response reliability calculation unit 206 sets the time when the first cooking equipment log is transmitted by the cooking equipment 10 or the time when the communication unit 201 receives the first cooking equipment log as the time when the cooking is completed. May be good.

Next, in step S42, the response reliability calculation unit 206 determines whether or not the second cooking equipment log has been received. Here, when it is determined that the second cooking equipment log has not been received (NO in step S42), in step S43, the answer reliability calculation unit 206 uses the current answer reliability calculation formula to determine the answer trust. Calculate the degree. The answer reliability calculation formula is a calculation formula for calculating the answer reliability.

On the other hand, when it is determined that the second cooking equipment log has been received (YES in step S42), in step S44, the answer reliability calculation unit 206 uses the current answer reliability calculation formula as the second cooking equipment log. Update according to. Then, in step S43, the answer reliability calculation unit 206 calculates the answer reliability using the updated answer reliability calculation formula.

FIG. 7 is a diagram for explaining an example of the answer reliability calculation formula for calculating the answer reliability. In FIG. 7, the vertical axis represents the response reliability F, and the horizontal axis represents the elapsed time t [sec] from the time when the cooking of the food is completed. The elapsed time t is 0 [sec] when the cooking of the food is completed. Further, in FIG. 7, the graph 301 is a graph showing the relationship between the response reliability and the elapsed time when the questionnaire information is presented, and the graph 302 is the response reliability and the elapsed time when the second cooking equipment log is received. It is a graph which shows the relationship with time.

As shown in FIG. 7, the response reliability F decreases linearly with the elapsed time t from the time t ₀ when the cooking of the food is completed. That is, the response reliability F is highest at time t ₀ when the cooking of the food is completed, and decreases with the passage of time. At this time, the answer reliability calculation formula for calculating the answer reliability F is expressed by the following formula (1).

F = -αt + 1000 ... (1)
In the above equation (1), F is the response reliability, α is the first response reliability reduction coefficient (initial value), and t is the elapsed time from the time when the cooking of the food is completed. Is. The deadline for presenting the questionnaire information is, for example, 1000 [sec].

In the graph 301, when the answer information by the time t ₂ when the answer reliability F is lower than the employed reference value 311 is not received, abort instruction information for stopping the presentation of the questionnaire information is transmitted to the cooking apparatus 10.

Further, when the answer reliability calculation unit 206 receives the second cooking equipment log, the answer reliability calculation formula updates the current answer reliability calculation formula according to the second cooking equipment log. At this time, the answer reliability calculation formula for calculating the answer reliability F is expressed by the following formula (2).

F = -α'(t-t ₁ ) -α t ₁ +1000 ... (2)
In the above equation (2), F is the response reliability, α is the first response reliability reduction coefficient (initial value), and t is the elapsed time from the time when the cooking of the food is completed. Α'is the second response reliability reduction coefficient (after update), and t ₁ is the time when the second cooking equipment log is received. The second response reliability reduction coefficient α'is larger than the first response reliability reduction coefficient α. The deadline for presenting the questionnaire information is, for example, 1000 [sec].

Further, in the graph 301, the degree of decrease in the response reliability per short time is the first degree of decrease, whereas in the graph 302, the degree of decrease in the answer reliability per short time is the first degree of decrease. It is changed to a second degree of decrease that is greater than.

In the graph 302, when the answer information by the time t ₃ when the answer reliability F is lower than the employed reference value 311 is not received, abort instruction information for stopping the presentation of the questionnaire information is transmitted to the cooking apparatus 10.

In this way, when the response reliability calculation unit 206 receives the second cooking device log from the cooking device 10 after transmitting the presentation instruction information, the response reliability calculation unit 206 determines the degree of decrease in the response reliability per unit time before receiving. The response reliability is calculated by changing to a second degree of decrease that is greater than the first degree of decrease in.

Subsequently, the adoption reference value determination process in step S27 of FIG. 5 will be described.

FIG. 8 is a flowchart for explaining the adoption reference value determination process in step S27 of FIG.

First, in step S51, the adoption reference value setting unit 207 acquires the number of response information received from other cooking devices for the questionnaire information transmitted to the cooking device 10 from the questionnaire response storage unit 210. The questionnaire response storage unit 210 stores the questionnaire identification information for identifying the questionnaire information and the response information for the questionnaire information indicated by the questionnaire identification information from the plurality of cooking devices in association with each other. The adoption reference value setting unit 207 acquires the number of response information by counting the number of response information associated with the questionnaire identification information for identifying the questionnaire information transmitted to the cooking device 10.

Next, in step S52, the adoption reference value setting unit 207 determines whether or not the number of acquired response number information is equal to or less than a predetermined number. The predetermined number to be compared depends on, for example, the period from the time when cooking is completed to the current time, the period from the time when cooking is completed to the time when the questionnaire is completed (the delivery deadline of the answer), and the client. Calculated based on the required number of responses requested. That is, the predetermined number is the number of response information that must be obtained at the current time in order to obtain the required number of responses by the end time of the questionnaire. The adoption standard value setting unit 207 multiplies the required number of answers by the period from the time when the cooking is finished to the current time, and divides the multiplied value by the period from the time when the cooking is finished to the time when the questionnaire is finished. By doing so, a predetermined number is calculated.

Here, when it is determined that the number of responses number information is equal to or less than a predetermined number (YES in step S52), in step S53, the employment reference value setting unit 207 lowers the current employment reference value. That is, as shown in FIG. 7, the employment standard value setting unit 207 changes the current employment standard value 311 to the employment standard value 312 lower than the employment standard value 311. As a result, the time at which the stop instruction information for stopping the presentation of survey information is transmitted, since it is changed to the slow time t ₄ than the time t _2, the low response reliability than the current answer reliability answer Information can also be collected, and the number of response information can be increased.

On the other hand, when it is determined that the number of response number information is larger than the predetermined number (NO in step S52), in step S54, the employment reference value setting unit 207 raises the current employment reference value. That is, as shown in FIG. 7, the employment standard value setting unit 207 changes the current employment standard value 311 to a employment standard value 313 higher than the employment standard value 311. As a result, the time at which the stop instruction information for stopping the presentation of survey information is transmitted, since it is changed to an earlier time t ₅ than the time t _2, the high response reliability than the current answer reliability answer Information can also be collected, and answer information with higher answer reliability can be collected.

In the present embodiment, the adoption standard value is changed according to the number of response information at the current time, but the present disclosure is not particularly limited to this, and the collection completion time of the response information is predicted and predicted. The recruitment standard value may be changed according to the collection completion time (delivery deadline of the answer).

In this case, first, the adoption reference value setting unit 207 predicts the collection completion time of the response information to the questionnaire information transmitted to the cooking device 10. The adoption standard value setting unit 207 acquires the number of response information received from other cooking devices for the questionnaire information transmitted to the cooking device 10 from the questionnaire response storage unit 210, and the number of acquired answer information and cooking Predict the collection completion time of the response information based on the period from the end time to the current time.

Next, the adoption reference value setting unit 207 determines whether or not the collection completion time exceeds the questionnaire end time (delivery deadline of the answer). When it is determined that the collection completion time exceeds the questionnaire end time, the recruitment standard value setting unit 207 lowers the current recruitment standard value. On the other hand, when it is determined that the collection completion time does not exceed the questionnaire end time, the adoption reference value setting unit 207 determines whether or not the collection completion time is earlier than the questionnaire end time. When it is determined that the collection completion time is earlier than the questionnaire end time, the recruitment reference value setting unit 207 raises the current recruitment reference value. On the other hand, when it is determined that the collection completion time is not earlier than the questionnaire end time, the recruitment reference value setting unit 207 maintains the current recruitment reference value as it is without changing it.
