Abstract
A device for assisting in assigning setting values of a compressor operation controller for starting or stopping one or more compressors, collecting discharged air of the compressors in an air tank, and supplying the air tank as a compressed air source in a predetermined pressure range, includes: an input unit that receives piping network information which is an element of a pressure loss of a piping flow from the compressor to a pressure control position of the controller, compressor specifications which are an upper limit of a discharge pressure of the compressor and a number of compressor starts/stops, a supply flow rate condition which is time change data of a flow rate flowing from the pressure control position of the controller, and a supply pressure condition which is a lower limit of the supply pressure at the pressure control position of the controller.
