- analysis is performed from past sales and various data of trouble occurrence frequency. If the annual average sales in the area P01 are 5.6 million yen and there are many cases of trouble occurrence frequency A, the degree of association that leads to the evaluation of this trouble occurrence frequency is set higher, and the trouble occurrence frequency B is set. If there are many cases, set a higher degree of association that leads to the evaluation of the frequency of trouble occurrence.

It may be determined whether they are the same or similar. Further, as long as the sales data is shown in a time-series transition graph, it may be determined based on the similarity of the trends.
- the reference refusal rate is the probability that the resident of the building structure actually requested the contractor to dispatch based on the air conditioning trouble, and the contractor could not accept the request and refused it.
- This refusal rate is expressed by the number of refusals for the number of dispatch requests.
- the number of dispatch requests, the number of times of refusal, and each region are managed by the contractor on the database 3.
- the refusal rate can be obtained by reading the number of refusals for the number of dispatch requests from the database 3 for the area where the refusal rate is actually desired to be known.
- the frequency of air-conditioning troubles depends on the sales in the area, as well as the refusal rate, because if the number of dispatch requests is too large, there are many cases of refusal. Therefore, by combining the reference rejection rate with the learning data in addition to the reference sales data, the trouble occurrence frequency can be determined with higher accuracy. Therefore, in addition to the reference sales data, the reference rejection rate is combined to form the above-mentioned degree of association.
- the input data is, for example, reference sales data P01 to P03 and reference refusal rate P14 to 17.
- the intermediate node shown in FIG. 5 is a combination of the reference sales data and the reference rejection rate as such input data.

- the degree of association indicates the degree of trouble occurrence frequency and the degree of relevance to the reference sales data and the reference rejection rate arranged on the left side.
- this degree of association is an index showing what kind of trouble occurrence frequency each reference sales data and reference rejection rate are likely to be associated with, and is based on the reference sales data and reference rejection rate. It shows the accuracy in selecting the most probable trouble occurrence frequency. Therefore, the optimum trouble occurrence frequency is searched for by combining these reference sales data and the reference rejection rate.
- w13 to w22 are shown as the degree of association. As shown in Table 1, these w13 to w22 are shown in 10 stages, and the closer to 10 points, the higher the degree of relevance of each combination as an intermediate node to the output, and conversely, 1 point. The closer they are, the less relevant each combination as an intermediate node is to the output.
- the search device 2 acquires in advance the degree of association w13 to w22 of three or more stages shown in FIG. That is, the search device 2 accumulates past data as to which of the reference sales data, the reference rejection rate, and the frequency of trouble occurrence in that case is suitable for determining the actual search solution. By analyzing and analyzing these, the degree of association shown in FIG. 5 is created.
- This analysis may be performed by artificial intelligence.
- the trouble occurrence frequency is analyzed from the past data. If there are many cases where the trouble occurrence frequency is A, the degree of association leading to this trouble occurrence frequency A is set higher, and if there are many cases of trouble occurrence frequency B and there are few cases of trouble occurrence frequency A, trouble occurs. The degree of association leading to the occurrence frequency B is set high, and the degree of association leading to the trouble occurrence frequency A is set low.

- Such degree of association is what is called learned data in artificial intelligence. After creating such learned data, when actually determining the trouble occurrence frequency from now on, the above-mentioned learned data will be used. In such a case, the area where the trouble occurrence frequency is actually to be determined is input in the same manner.

That is, the larger the degree of association w1 to w12, the heavier the weighting in the selection of the intermediate node 61 may be. However, the association degrees w1 to w12 may all have the same value, and the weightings in the selection of the intermediate node 61 may all be the same.
