The invention relates to a multi-terminal heating and cooling control method based on total current control, which prioritizes all heating and cooling terminals in the same heating and cooling time period; a central processing unit sends an electrification instruction to a terminal which is prioritized in the first place; the maximum rated current of a system is assumed to be a value; the central processing unit sets an upper current limit which is more than the present current of a current detection module detection system; if the maximum rated current of the system is more than the upper current limit, the central processing unit sends the electrification instruction to the terminal which is prioritized in the first place after an electrified terminal; and the process is repeated, until the present current in the system after one terminal is electrified is more than the set current, and the central processing unit immediately sends a power-off instruction to the terminal. The multi-terminal heating and cooling control method based on total current control has the beneficial effect that: the occurrence of various unsafe events caused by too large load can be effectively avoided.

A network system provides interventions to providers to reduce the likelihood that its users will experience safety incidents. The providers provide service to the users such as transportation. Providers who are safe and have positive interpersonal behavior may be perceived by users as high quality providers. However, other providers may be more prone to cause safety incidents. A machine learning model is trained using features derived from service received by users of the network system. Randomized experiments and trained models predict the effectiveness of various interventions on a provider based on characteristics of the provider and the feedback received for the provider. As interventions are sent to providers, the change in feedback can indicate whether the intervention was effective. By providing messages proactively, the network system may prevent future safety incidents from occurring.
