Classification: CPC H | IPC H

Claim 5:
6. A network design method executed by a network design apparatus for designing a network, comprising:
receiving input of a configuration condition for a network having a communication layer and at least one computing layer, a cost condition for the network, and a demand condition representing uncertain demand for the network, the network including a plurality of bases;
performing an operation for solving an adjustable robust optimization problem in which an objective function is to minimize a sum of a fixed cost and a variable cost for a resource placed at each base in the communication layer and the computing layer; and
determining a configuration of the network based on placement and capacity of a resource obtained by the performing of the operation,
wherein the adjustable robust optimization problem has a constraint condition using a variable indicating a ratio of, in a case where demand is assigned to a resource, a portion assigned to the resource with respect to total volume of the demand, and the variable is a variable that depends on a set of generated demands, and
wherein the demand condition includes a set of one or more bases among the plurality of bases, the one or more bases being associated with a first base among the plurality of bases, and resources placed at the one or more bases being assignable to the first base in response to the demand at the first base.
