1. A network management device that maps between i) a service order to request a service on a network and ii) a resource order to request a resource used for providing the service, the network management device comprising:
a mapping rule storage device that stores mapping rules for mapping between the service order and the resource order;
a mapping history storage device that, when a mapping is performed based on the mapping rules, stores a mapping history comprising i) an identifier of a service which is a mapping source for the mapping between the service order and the resource order, ii) a type of a mapping rule used for the mapping between the service order and the resource order, and iii) an identifier of a resource which is a mapping target for the mapping between the service order and the resource order, wherein the service is indicated by the service order and the resource is indicated by the resource order;
a first acquisition unit implemented by one or more processors configured to, when receiving a change service order to change the service, acquire, from the mapping history and based on the identifier of the service to be changed, i) mapping rules to be used for mapping of the change service order and ii) the identifier of the resource which is a mapping target corresponding to the identifier of the service to be changed;
a second acquisition unit implemented by the one or more processors configured to acquire, from the mapping rules acquired by the first acquisition unit, a mapping rule affected by the change of the service in the change service order; and
a creation unit implemented by the one or more processors configured to create a corresponding resource order by mapping of the change service order to change the service based on the mapping rule acquired by the second acquisition unit.
