Manufacturing system

A manufacturing system comprising:

• a first tank configured to store generation fuel;
• a manufacturing device constituting a production line in a factory, the manufacturing device including i) a wagon, ii) a first power generation device disposed on the wagon, the first power generation device being configured to generate power using the generation fuel, and iii) a manufacturing robot disposed on the wagon, the manufacturing robot being configured to manufacture industrial products using power supplied from the first power generation device;
• a transport robot configured to transport the generation fuel from the first tank to the manufacturing device;
• a first prediction unit configured to predict a demand amount of the generation fuel of the manufacturing device in a certain future period based on a planned quantity of the industrial products to be manufactured by the manufacturing robot and a product type of the industrial products;
• and
• a fuel production system configured to produce the generation fuel,
• wherein:
• the first tank includes:
• a main tank configured to store the generation fuel produced by the fuel production system, and
• a reserve tank configured to store generation fuel supplied from outside of the fuel production system, and
• the fuel production system is configured to:
• predict a production amount of the generation fuel to be produced in the certain future period based on an environment in which the generation fuel is produced;
• calculate a difference obtained by subtracting the demand amount from a sum of the production amount and a storage amount of the generation fuel in the main tank;
• in response to the difference being more than a threshold value, supply the generation fuel from the main tank to the transport robot;
• and
• in response to the difference being less than the threshold value, supply the generation fuel from the reserve tank to the transport robot.
