Abstract: An apparatus for automatically and manually route piping, the apparatus includes processing circuitry configured to receive an input of designated coordinates for a piping line routed so as to connect a plurality of instruments constituting a plant to each other in a virtual space for designing a plant, and assign a plurality of pieces of identification information to the piping line using the input designated coordinates as a boundary.

Abstract: An apparatus for designing a plant. The apparatus includes processing circuitry configured to: receive a specification of a position of a rack in a virtual space; receiving a setting of a pipe to be arranged in a layer indicating one of tiers into which the rack is partitioned in a height direction; receive, from a user, an operation of arranging a first object and a second object in the virtual space, the first object being a piece of equipment having a start point, the second object being a piece of equipment having an end point; determine a passable layer based on a type of the pipe and set a piping path through which the pipe is to pass; and perform pipe routing to connect a plurality of the pieces of equipment with the pipe based on the piping path and positions of the start point and the end point.

Abstract: A server (20) of a plant design system (1) includes a device input reception module (2033) for receiving an input operation (object allocation operation) for a type and allocation position of a block pattern or device to be allocated in a virtual space for plant design, a device allocation module (2034) for displaying a display based on information of the type and allocation position of the block pattern or device, and a pipe routing module (2037) for receiving an instruction operation (routing operation) to associate routing of piping with the block pattern or device and perform routing.
