Downstream derivation process automatic discovery method

The invention relates to the technical field of flow mining, in particular to a downstream derived flow automatic discovery method which comprises the following steps: S1, generating a flow chart according to EventLog, S2, generating time sequences for EventLog of each step of a target flow and EventLog of the first step of other flows, S3, comparing the time sequences and finding out the closest flow, and S4, if an appropriate downstream flow is not found in S3, finding out the flow chart according to the flow chart. And S3, segmenting the time sequence according to the enumeration type or whether a certain field has a value or not, and returning to S3 again. By means of the software method, in the downstream derived process discovery process, possible downstream processes can be automatically listed, the step in which the downstream processes are triggered can be determined, the whole process can be automatically achieved, and when different stages of the same process need to be executed in different system
