Abstract: A resource management plan creation support device reads in a travel schedule, represents, as one node, each path from an originating location to a terminating location of each leg included in a travel schedule that has been read in, and creates a network model by connecting together, using links, the legs over which consecutive travel is possible based upon the place and time. In addition, nodes representing auxiliary resources are added to the created network, and the network model is updated by adding links representing temporary usage of the auxiliary resources or temporary cessation of use of business-use resources. Also, by finding a path group encompassing each node of the network model so as to satisfy a pre-supplied condition (the condition of allocating resources to all of the legs), a management plan for resources which execute transport services is created.
