To provide an equipment plan optimization method and a device for it capable of making decision on selection of equipment to be discarded, new installation of equipment, and its timing about facilities consisting a production plant such as a petrochemical plant and service equipment supplying steam and electric power to the production plant on the basis of objective data rationally in a short time and independently of sense or experience of a person, and minimizing the equipment cost.
In this equipment plan optimization method, a fixed quantity is added to a variable defined by a basic model definition part 13 on the basis of data from an objective equipment setting part 11, a cost data inputting part 12A, and a specification data inputting part 12B about various facilities including the production equipment and the service equipment, and the total sum is found via a logical variable representing disposal, new installation, and an operation condition of the respective facilities. A condition giving the minimum sum of total costs over the whole of calculation object duration is found for deciding the equipment to be discarded, the equipment to be newly installed, and the business year for the new installation.
