Abstract: A work support system gives work support by using a work schedule which is created by dividing support target work into a plurality of division tasks and distributing a worker unit. The present system includes an interruption information acquisition part for acquiring interruption information, and a work schedule modification part for modifying the work schedule if the interruption information is acquired. The work schedule is modified by redistributing, to the division task started after the interruption event, the remaining worker unit excluding the worker unit distributed to the division task in which the interruption event occurs.

Abstract: A diagnosis apparatus for a valve system including a control valve, a servo valve for driving the control valve, and at least one servo module for providing a control signal based on an opening degree command value for the control valve to the servo valve is provided with: at least one opening degree detection part configured to detect an actual opening degree of the control valve; and a diagnosis part configured to acquire, from the opening degree detection part, a detected value of the actual opening degree of the control valve while a diagnostic opening degree command value is input to the at least one servo module, and diagnose an abnormality of the valve system on the basis of the detected value. The diagnostic opening degree command value changes in multiple steps between a maximum opening degree and a minimum opening degree through one or more intermediate opening degrees.
