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.

Abstract: A network simulation device of the present invention: accepts an input of first plane information being positional information on a network projected onto a coordinate plane having any two dimensions out of three dimensions as coordinate axes; creates network model information which defines a coordinate value of the remaining one dimension as unknown based on the accepted first plane information; accepts selection of the element having the coordinate value defined as unknown by a user from the elements which appear in the first plane information; accepts an input of second plane information being positional information on the network projected onto a coordinate plane having any two dimensions including the remaining one dimension as coordinate axes; and determines a numerical value of the coordinate value defined as unknown of the selected element in the created network model information based on the accepted second plane information.

Abstract: A monitoring device includes: a base information acquisition unit that acquires information on operation and fault of an equipment arranged at a base and position information relating to the equipment; a natural environment information acquisition unit that acquires natural environment information in a region; and an analysis unit that specifies a position of the equipment in which the fault has occurred from the information acquired by the base information acquisition unit, associates the position with a region of the natural environment information, and associates the equipment in which the fault has occurred with the natural environment information.
