Simulator, simulation method, and simulation program

A simulation method implemented by a computer for estimating a behavior of a system, the method comprising:

• virtually creating a system including a carrier in a three-dimensional virtual space, the created system including a visual sensor virtually located at a first position on a transporting path associated with the carrier, and a processing device virtually located at a second position on the transporting path;
• performing image measurement of preliminarily obtained image data corresponding to processing performed using the visual sensor;
• executing a control operation for generating a control instruction directed to the processing device based on a measurement result obtained from the image measurement and for generating a read instruction for reading the image data to start the image measurement;
• storing the image data read in response to the read instruction in a manner associated with information indicating a position or a displacement of the carrier, the position or the displacement serving as a reference for the image measurement performed in response to the read instruction;
• and
• reproducing a behavior of the created system based on time-series data for the control operation output as a result of the executing step and information associated with the stored image data.
