Abstract: A control method and apparatus for a traffic light in a road network, and an electronic device and a computer-readable storage medium. A road network comprises a plurality of road sections and an intersection, which is formed by the plurality of road sections. A traffic light is used for regulating and controlling traffic at the intersection. The control method comprises: acquiring real-time road condition state information of a plurality of road sections in a road network, which are connected to an intersection (S10); according to the road condition state information, selecting a next-hop phase of a traffic light from a plurality of preset phases of the traffic light (S20); and controlling a phase of the traffic light to be updated to the next-hop phase (S30). By means of the method, a phase is intelligently and dynamically selected according to a real-time road condition, such that the waiting time of a vehicle, the queuing length of the vehicle, etc.

Abstract: An apparatus for managing production of one or more products includes a business backend; an interface service; a persistent data storage; a processor; and a message middleware. The business backend is configured to extract and organize data; and dispatch business data to the interface service. The interface service is configured to perform data validation on the business data received from the business backend; and transmit the business data to the persistent data storage and the message middleware. The persistent data storage is configured to store the business data received from the interface service as a reference for the calculation and analysis; and transmit data to the processor. The processor is configured to calculate overstock quantity and determine overstock type. The message middleware is configured to receive the business data from the interface service, and receive analysis results from the processor; and transmit the analysis results to interface service.
