Abstract
A plant simulation device includes a first storage that stores a model that models a state of a facility in a plant, a first parameter that is fixed at a start operation of the plant, and a second parameter that is varied during an operation of the plant, the first parameter and the second parameter being set in the model, and a simulator that compares a process value of the facility with a simulated value calculated using the model and that adjusts the first parameter and the second parameter.
