Title:
SYSTEM, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/065640
Kind Code:
A1
Abstract:
It is rare for the operation of the production site to proceed according to the initially formulated plan, and many deviations occur between the actual operation and the plan. Accordingly, the performance of the production site is preferably analyzed while considering these deviations. Provided is a system including a planning section that generates a production plan for controlling a production site during a target interval, using a planning model; a retrospective planning section that generates a retrospective plan, which is a production plan that retrospectively reflects at least one of unplanned events that occurred after generation of the production plan, using the planning model; and an analyzing section that analyzes production performance of the production site during the target interval, based on the production plan and the retrospective plan.
