Operation support device and operation support method

An operation support device including a support function for presenting a control candidate table for managing a plurality of control candidates to an operator, the operation support device comprising:

• a similarity determination unit, implemented by a processor, that determines a similarity between actual measured data and simulated data, the actual measured data being measured in an operation target after control for the operation target is executed based on, among the plurality of control candidates, a control candidate corresponding to an event occurred in the operation target, and the simulated data being obtained by a simulation assuming a system state of the operation target after the control for the operation target is executed based on system data indicating a state of the operation target before the control for the operation target is executed;
• a control candidate table update unit, implemented by a processor, that updates the control candidate table in accordance with a determination result of the similarity determination unit:
• a system state analysis unit, implemented by a processor, that executes the simulation assuming the system state of the operation target after the control for the operation target is executed based on the system data indicating the state of the operation target before the control for the operation target is executed, and creates an analysis result as the simulated data;
• and
• a stability determination unit, implemented by a processor, that determines priority of each control candidate managed by the control candidate table based on the simulated data created by the system state analysis unit, wherein the control candidate table update unit updates the priority of each control candidate managed by the control candidate table in accordance with a determination result of the stability determination unit.
