Simulation device

A system comprising:

• a simulation device that simulates movement of a vehicle between a plurality of ports in a shared traffic service and that included processing circuitry configured to calculate a work time in a relocation port that is a port to be a target of relocation of the vehicle, and simulate the relocation based on the work time;
• and
• a management device configured to store port information including an actual number of vehicles available at a first time at each of the plurality of ports, and vehicle carrier trailer information including actual position information of a vehicle carrier trailer at the first time;
• wherein the processing circuitry is configured to
• acquire the port information and the vehicle carrier trailer information from the management device and, based on the port information and the vehicle carrier trailer information, calculate the number of vehicles available at a second time later than the first time for each of the plurality of ports and the position information of the vehicle carrier trailer at the second time, and
• determine from among the plurality of ports, the relocation port based on the number of vehicles available at the second time for each of the plurality of ports and the position information of the vehicle carrier trailer at the second time,
• the work time includes a carrying time required for a worker to carry a target vehicle that is a vehicle to be relocated between a vehicle carrier trailer and the relocation port, the vehicle carrier trailer transporting the target vehicle between the relocation ports,
• the processing circuitry calculates the carrying time based on map image data indicating a map around the relocation port and by using a machine learning model which is learned by using map image data around a port as an explanatory variable and using a time required for one carrying work in the port as an objective variable,
• the work time includes a maintenance time for maintaining the relocation port, and
• the processing circuitry calculates the maintenance time based on an elapsed time that has elapsed since a worker visited the relocation port last time.
