The invention relates to a system processing method which includes the following steps: S1, obtaining basic information of systems, S2, selecting devices according to the basic information of the systems and combining the devices into to-be-selected systems, S3, building a device solving model to obtain the throughput capacity of the devices, S4, building a subsystem solving model to obtain the throughput capacity of subsystems formed by combining the devices in the same framework layer, S5, building a system solving model to obtain the response time of the to-be-selected systems, S6, determining whether the to-be-selected systems meet conditions or not according to the response time, and S7, outputting the to-be-selected systems meeting the conditions. By means of the system processing method, resource information of the systems can be accurately obtained, and waste caused by resource redundancies or abnormal work of the systems when resources are insufficient can be avoided.
