Simulator, simulation method, and simulation program

A simulation method implemented by a computer for estimating a behavior of a system comprising a carrier having a transporting surface for continuously transporting a target that is placed thereon and a processing device for picking up and placing the target onto the transporting surface, the method comprising:

• virtually creating the system in a three-dimensional virtual space;
• updating positions of a plurality of targets placed on the transporting surface in the three-dimensional virtual space based on a corresponding movement of the carrier, and updating the position of the target picked up by the processing device in the three-dimensional virtual space in a manner associated with a behavior of the processing device;
• generating a control instruction for the behavior of the processing device based on a position of each target of the plurality of targets in the three-dimensional virtual space;
• and
• correcting the position of the target in a horizontal direction in the three-dimensional virtual space in accordance with a transporting speed in the horizontal direction in the three-dimensional virtual space at a timing in response to the processing device releasing the target, wherein
• updating the positions comprises, in response to the processing device placing the target within a predetermined range from the transporting surface, associating the target with the transporting surface and updating the position of the target.

A non-transitory computer readable medium storing a simulation program for estimating a behavior of a system comprising a carrier having a transporting surface for continuously transporting a target that is placed thereon and a processing device for picking up and placing the target onto the transporting surface, the simulation program, when read and executed, causing a computer to implement:
