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.

A production efficiency improvement support system calculates a cycle time erc. based on results of detecting an operating status of production equipment, and displays a chart showing a time series variation of the cycle time etc. The cycle time is displayed such that a variation of the cycle time is visually recognizable. The chart displays information regarding a production volume that is the most important variable in production management on a first row and a second row from the top, and displays information regarding the operating status of the production equipment related to the production volume on bottom two rows (a fourth row and a fifth row). The chart also displays the operating status of the production equipment between these pieces of information. Displaying these indexes in the form of a chart facilitates visual recognition of how to improve the cycle time and effectively supports improvement of the production efficiency.

A production efficiency improvement support system calculates an operational availability and a cycle time, based on results of detection of an operating status of production equipment, and displays a chart. An axis of the cycle time is set to be shorter rightward. The results of detection are displayed in such a mode that variations are recognizable, like points pp1 and points pp2. The points pp1 and the points pp2 have different countermeasures applied for improvement of the production efficiency and are accordingly displayed in different display modes. A point p1 and a point p2 indicating values of an actual cycle time and an actual operational availability are also displayed as representative values of the results of detection. Displaying these indexes in the form of a chart facilitates visual recognition of how to improve the operational availability and the cycle time and effectively supports improvement of the production efficiency.

The present disclosure relates to systems and/or methods for automatically collecting and evaluating PI data from one or more controllers of a production facility. For example, various embodiments described herein can relate to a method for evaluating the performance of a production facility that includes establishing an authenticated connection with a performance indicator server in accordance with a defined schedule. The performance indicator server stores data from one or more controllers that manage assets of a production facility. The method can include automatically evaluating a performance of the production facility, via a performance evaluation algorithm, in response to collecting performance indicator data via the authenticated connection.
