Title:
COMPUTATION DEVICE, PLANNING ASSISTANCE METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/106125
Kind Code:
A1
Abstract:
Provided is a computation device with which it is possible to shorten the time involved in creating an operation plan in which uncertainty is accounted for. A draft scenario generation unit 33 generates a plurality of draft scenarios on the basis of a risk distribution 21 in which uncertainty is expressed by probability. A baseline draft plan generation unit 34 generates a baseline draft plan on the basis of a draft plan definition region 22 that indicates the range of determinate parameter values. An approximation evaluation unit 35 acquires, using an approximation evaluator 27, an approximation evaluation result obtained by evaluating an operational draft plan that combines the draft scenarios and the baseline draft plan. A draft scenario aggregation unit 36 aggregates the draft scenarios into a plurality of scenario groups on the basis of the approximation evaluation result. A representative scenario selection unit 37 selects, for each scenario group, one of the draft scenarios belonging to the scenario group as a representative scenario, on the basis of the approximation evaluation result.
