OPERATING COST ASSESSMENT METHOD AND OPERATING COST ASSESSMENT PROGRAM

摘要

This operating cost assessment method has: a diagnosis step for inspecting a plurality of plant devices (1) of a model to be assessed which are operating in a plant (P), and diagnosing the operating status of each of the plant devices (1) on the basis of the inspection results; an accumulation step for accumulating operation start time information, inspection time period information and operating status information in a storage device for each of the plant devices (1); a device lifespan calculation step for calculating the device lifespan of the model to be assessed; an event prediction step which, on the basis of the device lifespan, predicts the frequency of installation, maintenance and the like which will occur during the period of operation of the plant devices (1) of the model being assessed; and a cost calculation step for calculating the total operating cost incurred in order to operate the plant devices (1) of the model being assessed over the period of operation thereof on the basis of the prediction.
