As a result of determining whether there is a supplier with experience in supplying the first light source 121 in step S704, if it is determined that there is no supplier with experience in supplying the first light source 121, in step S706, the server ( 200 ) may obtain first brand information that is the brand of the first light source 121 . Here, the first brand information may be obtained through a database or an external server.

In step S707, the server 200 may analyze suppliers who have experience in supplying light sources included in the first brand based on the first brand information.

Specifically, the server 200 may analyze, based on the first brand information, which supplier among suppliers who have experience in supplying light sources included in the first brand is familiar with the first brand.

In step S708, the server 200 may select a supplier to supply the first light source 121 based on the analysis result.

Specifically, the server 200 determines that a supplier with a short supply period among suppliers who have experience in supplying light sources included in the first brand is intimate with the first brand, and selects the supplier as the first light source 121. may be selected as a supplier to supply, and a supplier who has supplied a lot of light sources included in the first brand may be determined to be intimate with the first brand, and the supplier may be selected as a supplier to supply the first light source 121. have.

In step S709, when a supplier to supply the first light source 121 is selected, the server 200 purchases the first light source 121 through the supplier selected as the supplier to supply the first light source 121. A notification message of recommendation may be transmitted to the manager terminal 300 .

8 is a flowchart illustrating a process of selecting a supplier to supply a first light source according to an embodiment.

Referring to FIG. 8 , first, in step S801, the server 200 may classify a supplier having experience in supplying a light source included in a first brand among suppliers into a first group.

Specifically, the server 200 may obtain first brand information that is the brand of the first light source 121, identify light sources sold under the first brand based on the first brand information, and include them in the first brand. source of light can be extracted. The server 200 may extract suppliers who have experience in supplying light sources included in the first brand and classify them into a first group.

In step S802, the server 200 may obtain supply experience data corresponding to the first brands of the suppliers classified into the first group.

That is, the server 200 may obtain supply experience data of suppliers classified into the first group, and extract supply experience data corresponding to the first brand based on the obtained data. Here, the supply experience data corresponding to the first brand is how many light sources sold under the first brand were supplied, how long it took from when an order for light sources sold under the first brand was obtained to when the supply was completed, and Supply experience data related to the light source sold under the first brand, such as user satisfaction with the light source sold as .

In step S803 , the server 200 may generate supply required periods from the start of an order to the supply completion in the supply experience data corresponding to the first brand.

That is, in the supply experience data corresponding to the first brand, the server 200 completes the supply when the user received the light source sold under the first brand from the start of the order requesting the supply of the light source sold under the first brand from the user. You can create a supply lead-time to a point in time.

For example, as a result of checking the supply experience data of the third supplier, which is a supplier classified as the first group, a supply request for a light source sold under the first brand is received from the first user on April 1, and the first If the date on which the user received the corresponding light source is April 15, the server 200 may generate a supply required period of 14 days.

In step S804, the server 200 may generate average supply periods corresponding to each of the suppliers classified into the first group, based on the supply periods.

Specifically, the server 200 may extract supply periods of light sources sold under the first brand of suppliers classified as the first group, and average supply periods by calculating an average of the supply periods for each supplier. can create

For example, as a result of checking the supply period of the first supplier, which is a supplier classified as the first group, if it is 14 days, 6 days, and 10 days, respectively, the server 200 calculates the average supply period of the first supplier. Can be created in 10 days.

In step S805, if the average supply period is shorter than the predefined critical period, the server 200 may increase the weight for the period of supply in inverse proportion to the average period of supply among the weights in the criteria for selecting a supplier. .

Specifically, the server 200 generates an average supply period of suppliers classified as the first group, extracts suppliers whose generated average supply period is shorter than a predefined critical period, and supplies suppliers of the corresponding suppliers. Among the weights in the criteria for selecting a company, the weight for the required period can be increased in inverse proportion to the average supply required period.

For example, the average lead-time for supplier 1, which is a supplier classified as group 1, is 10 days, the average lead-time for supplier 2 is 6 days, and the average lead-time for supplier 3 is 6 days. is 12 days, the average supply period of the 4th supplier is 17 days, and the predefined critical period is 14 days, the server 200 determines that the average supply period of 17 days is the critical period in the case of the 4th supplier. Since the required period is longer than 14 days, no weight is given for the required period, 10 points are given to the second supplier, 6 points are given to the required period, and 6 points are given to the 3rd supplier. A supplier can be given a weight of 5 points for lead time.

In step S806, the server 200 may select a supplier to supply the first light source 121 by applying a weight.
