  • Publication number: 20220075355
    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.

  • Patent number: 10162909
    Abstract: In a three-dimensional model design assistance system in which design rules are registered in advance, it is difficult to manually input all of an enormous number of device placement rules including the distances and directions between respective devices in a design. Information relating to the relative distances and relative directions between respective devices included in performance CAD data is extracted. With respect to each of the extracted relative distances and relative directions in a plurality of cases, a correlation with a performance requirement specification value, and a placement priority are calculated and held as device placement rules. At design time, requirement specifications are inputted, accessory devices are determined, and thereafter the devices are placed according to placement priorities on CAD on the basis of the device placement rules.

  • Patent number: 10120960
    Abstract: A device arrangement rule generation unit generates device arrangement rules each including a past installation space of devices and relative direction information indicating a relative direction between devices that were arranged in the past installation space. An input unit inputs information on a new installation space and devices to be arranged in the new installation space. A device arrangement rule extraction unit extracts device arrangement rules each including the devices to be arranged in the new installation space input by the input unit. A device arrangement calculation unit calculates an arrangement position of the devices to be arranged in the new installation space based on relative direction information included in one of the device arrangement rules extracted by the device arrangement rule extraction unit and based on dimensions of the devices to be arranged in the new installation space input by the input unit.

  • Publication number: 20110301999
    Abstract: Data to support a determination as to whether or not a project can be executed, etc., is provided on the basis of a cost estimation value of project deliverables. Regarding a risk event parameter group which is a collection of risk event parameters indicating a degree of estimation risk for each of a plurality of estimation risk events, the similarity between risk event parameter groups of a plurality of past projects and a risk target parameter group of a target project is obtained (S41 to S43), the top N past projects in terms of the similarity to the target project is extracted from the plurality of past projects (S43), a cost deviation of a cost estimation value of the target project is obtained from the cost estimation value and the actual value of each of the N past projects (S45, S46), cost fluctuation information is created on the basis of the cost deviation of the target project (S47), and the cost fluctuation information is displayed.
