Job optimization processing method and device

The invention discloses a job optimization processing method and device, and relates to the technical field of system operation and maintenance optimization. A specific embodiment of the method comprises the following steps: determining a delay job in a target system; obtaining a job dependence graph of the target system; determining a key path corresponding to the delayed operation according to the operation dependency graph; the key path is a path with the maximum weight sum in alternative paths taking a node corresponding to the delay operation as a starting point; determining a downstream job of the delay job in the critical path as an associated job of the delay job; and determining the execution duration corresponding to the key path, determining an optimization strategy according to the execution duration and the expected completion time of the target system, and performing operation optimization processing on the associated job. According to the implementation mode, under the condition of operation de
