A load control system may include a load control device and a load, in which the load control device is adapted and configured to control power supplied to the load. The load may include metrology adapted and configured to determine an amount of power output of the load at each of a plurality of load control levels of the load control device to translate linear load control level to linear power output. In a demand response system, when the load control system is directed to reduce its power consumption by a given amount, the load control device may be changed to an appropriate load control level so that the power consumption of the associated load is reduced by the given amount in the demand response request.

Disclosed is an injection molding system including: a state observation section observing, when injection molding is performed, physical-amounts relating to the injection molding that is being performed; a physical-amount data storage section storing the physical-amount data; a reward-conditions setting section setting reward conditions for machine learning; a reward calculation section calculating a reward based on the physical-amount data and the reward conditions; an operating-conditions adjustment learning section performing machine learning of adjusting operating conditions based on the reward calculated by the reward calculation section, the operating conditions, and the physical-amount data; a learning-result storage section storing a learning result of the machine learning by the operating-conditions adjustment learning section; and an operating-conditions adjustment-amount output section determining and outputting an operating condition to be adjusted and an adjustment amount based on the machine learning by the operating-conditions adjustment learning section.
