POLICY DETERMINATION SYSTEM AND POLICY DETERMINATION METHOD

摘要

This policy determination system has stored in a storage device: a plurality of proposed policies for resolving a problem in a specific region of a target area; problem resolution information in which problem resolution target values and problem resolution degrees are associated with each other; cost information storing target values of cost required to resolve the problem; a predicted quantity of occurrence of the problem; a suppliable quantity of each of the plurality of proposed policies with respect to the problem; and a predicted cost for executing the proposed policies. On the basis of the suppliable quantity with respect to the problem and the predicted quantity of occurrence of the problem, the policy determination system: identifies, from the problem resolution information, the problem resolution degrees associated with the problem resolution target values; identifies, from the cost information, the target values of cost corresponding to the predicted cost if the proposed policies were to be executed; calculates the cost-effectiveness of the proposed policies on the basis of the identified problem resolution degrees and the identified target values of cost; and selects from among the plurality of proposed policies two or more specific proposed policies having relatively high calculated cost-effectiveness.
