Abstract: 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.
