    Abstract: An acquisition unit acquires specification information about a robot that is a component of a robot cell system, member information including shape information about a member, other than the robot, which is also a component of the robot cell system, and work information relating to work to be performed by the robot. A layout planning unit calculates, based on the specification information, the member information, and the work information, one or more layout candidates for the robot and the member in the robot cell system. A pose planning unit calculates, for each layout candidate, a set of combinations of a start pose at a start point and an end pose at an end point of each operation of the robot. A route planning unit calculates, for each layout candidate, a set of routes from the start pose to the end pose of each combination of the start pose and the end pose.
