Abstract: Implementations of this specification provide graph data processing systems and methods. An example graph data processing system includes a data storage system and a graph computing engine. The data storage system is configured to store a plurality of pieces of graph data corresponding to a plurality of versions, where the plurality of pieces of graph data are generated based on a plurality of groups of service data generated by a target service system in a plurality of consecutive time intervals. The graph computing engine is configured to receive a graph feature computing request. The graph computing engine is further configured to search the plurality of pieces of graph data stored in the data storage system for a plurality of pieces of target graph data corresponding to the plurality of target versions, and compute graph features of the plurality of pieces of target graph data.

Abstract: Provided is an optimized decision-making system for multiple ore dressing production indexes based on a cloud server and mobile terminals, including mobile intelligent terminals, a cloud server, a mobile industrial private cloud server, a collecting computer and process controllers PLC or DCS. The mobile industrial private cloud server calculates out multiple decision-making result solution sets; the intelligent mobile terminals determine the final decision-making results; the mobile industrial private cloud server calculates out process control set values; the mobile intelligent terminals determine the final process control set values; and the process controllers PLC or DCS control equipment on a production line for production according to the final process control set values. The present invention further provides an optimized decision-making method for multiple ore dressing production indexes adopting the optimized decision-making system.
