Abstract: There is provided a network management device (1) including a capacity management unit (10) for managing the capacity in a network to be managed and a storage unit (20) for storing management information. The storage unit stores specification information of entities included in the network, and entity information including information indicative of relationships between the entities. The capacity management unit 10 includes a capacity request acquisition section (11) which receives a generation request of a first entity; reads the specification information about the first entity from the storage unit, and determines whether or not the first entity needs to consume a resource; when it is determined that the first entity needs to consume a resource, identifies a second entity capable of providing capacity consumed by the first entity, based on the entity information stored in the storage unit; and outputs information about the identification result.

Abstract: A data search apparatus according to an embodiment includes: an input unit; and a storage apparatus configured to store master data names managed with master data. The data search apparatus calculates edit distances between master data names stored in the storage apparatus and input data names input in the input unit, calculates degrees of similarity between the master data names and the input data names based on term frequency and inverse document frequency of the master data names and the input data names, performs processing for narrowing down candidates for the data name being searched for in the master data names based on the calculation results and adjacency information indicating adjacency relationships between the master data names and the input data names, and outputs information indicating correspondence between the master data names and the input data names based on the candidate for the data name being searched for, the candidate for the data name being obtained through the narrowing-down processing.

Abstract: A delivery support device includes a derivation unit that derives a route of a resource in a delivery apparatus, for minimizing a maximum value of a time during which the resource is exhausted at a plurality of first locations. The derivation unit derives the route on the basis of a branch-and-bound method using a relaxation problem of aggregating a plurality of second locations of which a delivery order is not determined among the plurality of first locations into one point.
