摘要

PROBLEM TO BE SOLVED: To provide a plant operation optimization device, capable of determining a stable optimum solution even with dispersion of state variables while applying an existing optimization method.;SOLUTION: An evaluation index creation means 13c creates an evaluation index considering the dispersion of state variables of a plant 11 at a search point where search is performed by an optimum solution search means 13b based on dispersion of controllability of field equipment to an optimum operation instruction and an analysis result of features of a model of the plant 11. An optimum solution reevaluation means 13d reevaluates the operation state around an optimum solution searched by the optimum solution search means 13b based on a reevaluation function considering the evaluation index formed by the evaluation index creation means 13c, whereby the optimum solution searched by the optimum solution search means 13b is selected.;COPYRIGHT: (C)2009,JPO&INPIT
