Abstract: A maintenance support system for a plurality of maintenance-target apparatus in a plant includes a maintenance information delivery unit that delivers maintenance information Im that indicates an operational status of each maintenance-target apparatus to maintenance personnel every preset time T, wherein the maintenance information delivery unit delivers predictive information If to the maintenance personnel at a specified time Tf between the previous delivery of the maintenance information Im and the next delivery of the maintenance information Im, the predictive information If providing predictions regarding the operational status of each maintenance-target apparatus at the next delivery of the maintenance information Im.

Abstract: The present invention includes a threshold value calculation unit that calculates a normal range that is a range of values that are taken when a steam trap is in a normal state, by using a predetermined calculation reference, based at least on state values with normal determination results, from among state values that have been stored in the storage unit during a predetermined period. A determination unit can perform predictive determination to determine whether the steam trap is in a normal state or a state that indicates an inclination toward a bad state and is highly likely to change to a bad state, by determining whether or not the state values are in the normal range, and the threshold value calculation unit performs accuracy determination to determine the accuracy of the predictive determination based on the results of the predictive determination regarding the state values stored in the storage unit, and adjusts the calculation reference based on the result of accuracy determination.

Abstract: A management system includes a map information storage unit, an association information storage unit, a map information generation unit, a display unit, and an operation unit. The map information generation unit generates display arrangement map information and display process map information for displaying an arrangement map that indicates arrangement positions and a process map that indicates a connection relationship of a plurality of system devices that constitute a process system. Also, the map information generation unit generates the display process map information in a display mode that enables other system devices associated with a designated system device to be identified, based on information stored in the association information storage unit.

Abstract: A risk evaluation system includes a storage unit, an operation unit, a calculation unit, a risk evaluation unit and a display unit. The calculation unit calculates first and second factors for use in risk evaluation relating to specific constituent devices on the basis of predetermined information about the specific constituent devices. The risk evaluation unit generates risk evaluation information to be used for displaying a device risk evaluation matrix defined by two axes of the first factor and the second factor and including plot images plotted based on the first and second factors of the specific constituent devices. Further, the risk evaluation unit generates the device risk evaluation information in identifiable displaying mode to allow identification of plot images of specific constituent devices constituting a same process.
