## Abstract

An inventory management device (1) includes an acquisition unit (11) that acquires a first learned model related to inventory management of old products, and relevance information related to relevance between the old products and new products, an assessment unit (14) that assesses whether or not the first learned model is applied to inventory management of the new products, based on the relevance information, and a determination unit (15) that applies the first learned model to the inventory management of the new products when the assessment unit (14) assesses that the first learned model is applied, and determines a policy for the inventory management of the new products.

## Claims

### Claim at position 1

1: An inventory management device comprising:
an acquisition unit configured to acquire a first learned model related to inventory management of first products, and relevance information related to relevance between the first products and second products;
an assessment unit configured to assess whether or not the first learned model is applied to inventory management of the second products, based on the relevance information; and
a determination unit configured to apply the first learned model to the inventory management of the second products when the assessment unit assesses that the first learned model is applied, and determine a policy for the inventory management of the second products.

### Claim at position 2 (depends on 1)

2: The inventory management device according to claim 1, wherein the determination unit combines the first learned model with a second learned model related to the inventory management of the second products to determine the policy for the inventory management of the second products.

### Claim at position 3 (depends on 2)

3: The inventory management device according to claim 2, wherein the determination unit combines the first learned model with the second learned model to determine the policy for the inventory management of the second products so that a weight of the second learned model increases as a period of time elapses.

### Claim at position 4 (depends on 1)

4: The inventory management device according to claim 1,
wherein the acquisition unit acquires SNS data before a release date of the first products and the second products as the relevance information, and
the assessment unit assesses that the first learned model is applied to the inventory management of the second products when the number of transmissions regarding the first products and the number of transmissions regarding the second products in the SNS data are similar to each other.

### Claim at position 5 (depends on 1)

5: The inventory management device according to claim 1,
wherein the acquisition unit acquires product features of the first product and the second product as the relevance information, and
the assessment unit assesses that the first learned model is applied to the inventory management of the second products when the product feature of the first product and the product feature of the second product are similar to each other.

### Claim at position 6 (depends on 1)

6: The inventory management device according to claim 1, further comprising:
a demand prediction unit configured to construct a demand prediction model for the second products, based on sales data of third products having high relevance to the second products,
wherein the determination unit determines the policy for the inventory management of the second products in consideration of the demand prediction model.
