specific Embodiment approach

[0029] The specific implementation of the workflow modeling method based on log record mining and combination verification provided by the present invention is as follows:

[0030] (1) Export the workflow log from the database, delete redundant information, including dividing the log into a circular structure and without loop constructs Each log contains several execution traces.

[0031] (2) Count the number of task nodes, including the number of occurrences of a single task node and the number of occurrences of a single node and its follower nodes. The specific execution steps are as follows:

[0032] (2.1) Count the number of occurrences of a single task node: set Initialized to 0, traverse all ,like ,but plus 1.

[0033] (2.2) Count the number of co-occurrences of a single task node and its follower nodes: First, analyze the relationship between task nodes, determine the follower relationship between task nodes, and obtain the set of follower nodes for each tas...

Abstract

The invention discloses a workflow modeling method based on log record mining and combination verification. The method comprises the following steps of: deriving workflow logs from a database, deleting redundant information, and classifying the logs; scanning loop-free workflow logs, counting the occurrence frequency of task nodes, and recording following task nodes of each task node, and the co-occurrence frequency of the task node and the following task nodes; constructing a directed task graph according to each task node and a following task node set; adding a control structure to the directed task graph according to the occurrence frequency of the task nodes and the co-occurrence frequency of the task nodes and the following task nodes; and converting the directed task graph into a workflow network, and verifying the accuracy of a mined model by using an incidence matrix and a state equation of the workflow network. By adoption of the method, a sequence structure, a selection structure, a circulation structure and a parallel structure in a workflow can be effectively constructed, formal verification is performed, and the accuracy of the model is ensured.

Description

technical field [0001] The invention belongs to the technical field of software business process management, and relates to a workflow modeling method based on log record mining and combination verification. Background technique [0002] Workflow mining was first used in the field of software engineering management. In the early system design, the cognition of business analysts and managers to the business was the main source of the software designer's needs and analysis, which would make it exist effectively. Certain subjectivity, at the same time, unexpected situations that may arise during actual operation cannot be effectively handled, which will also affect the efficiency of software use. In some cases, accurate modeling of workflow is relatively difficult, because some elements can only be determined when the workflow is running. Therefore, the perfection of the workflow model should not be overly demanding when modeling the workflow. It is necessary to make the workf...
