Abstract: An assembly order generation device includes a radial/axial direction component detector which detects a component existing in a radial direction of a featured shape and a component existing in an axial direction of the component in a 3D CAD model. A directed graph expresses a connection precedence relationship in which the component is depicted by a node and a connection precedence relationship between the components which is depicted by a directed edge based on the detection result. A unit of disassembling and a disassembling order proposal based on the connection precedence relationship is generated, and an assembling order/direction/motion generation unit generates a disassemble direction based on the unit of disassembling and the disassembling order proposal and an assembly graph to generate a disassembling direction and a disassembling order, and reversely converts the generated disassembling direction and the generated disassembling order to derive an assembling order and an assembling direction.

Abstract: A line configuration planning device determine a task sequence during production of the to-be-produced product and the task time by the worker or the automatic machine for each task on the basis of the task information and the task time information. The line configuration planning device determine a required cycle time for producing the to-be-produced product on the basis of the production plan information. The line configuration planning device generate, on the basis of the determined task sequence, task time, and required cycle time, an allocation proposal for the worker and the automatic machine such that an estimated cycle time for producing the to-be-produced product is less than or equal to the required cycle time. The line configuration planning device determine a production line configuration for the to-be-produced product on the basis of the allocation proposal and the equipment configuration information.

Abstract: In an arrangement design of a robot cell and of robot work, a planning device searches an arrangement graph, that shows candidates for relative positions and orientations between a robot and a fixture; searches a disassembly task sequence, of disassembly tasks that are operations of the robot for disassembling components from the assembly in an arrangement of the relative positions and orientations between the robot and the fixture, and searches for, based on a point sequence of positioning relay points of the robot, a trajectory in which the robot disassembles the components from the assembly; and generates assembly tasks formed of a point sequence obtained by reversing the point sequence of the relay points, an assembly trajectory of the robot which is reverse to a disassembly trajectory formed of interpolation points between the point sequences, and an assembly sequence, which is a reverse order of the disassembly task sequence.

Abstract: A technique of calculating a trajectory including preferable suspension posture and arcuate trajectory without interference is provided in relation to the system that calculates the trajectory in the suspension conveyance using conveying equipment. A trajectory calculation system generates a trajectory on which a conveyance object is conveyed on a trajectory including an arcuate trajectory by conveying equipment with a suspension posture between waypoints inside a building; calculates a candidate of the suspension posture of the conveyance object inside the building by using building data, conveyance object data, kinematic parameter of conveying equipment, waypoint information and others; calculates a candidate of the trajectory including the arcuate trajectory; determines presence or absence of interference between the building and the conveyance object in the suspension posture on the trajectory of the candidate; and determines a trajectory including the suspension posture and the arcuate trajectory without interference.
