Abnormal segment extraction method, readable storage medium and terminal for workflow network inspection

Abstract

The invention provides a method for extracting abnormal fragments of workflow network inspection, including: constructing an initial WFD network of the model, and generating data constraints; constituting a corresponding constraint analysis mode according to the data constraints, the corresponding relationship between data and positive and negative constraints, and constraints and Correspondence between guard function values; generate WFDC network model; generate reachable configuration CDC diagram with data constraints; define multi-level rationality of WFDC network according to network characteristics of WFDC network; To determine the rationality level of the network model, obtain the detection result, and convert the reachable configuration CDC graph into the minimum complete CDC tree when the detection result is an error, and extract the abnormal path in which there is an error state; according to the obtained The extracted abnormal path and data constraint features are used to extract the abnormal fragment of the abnormal path. The invention solves the problem of automatic detection of abnormal fragments in the prior art when a detection result failure occurs in the system.

Description

technical field [0001] The invention relates to the technical field of system flow error detection of a work network, in particular to a method for extracting abnormal segments of a work flow network inspection, a readable storage medium and a terminal. Background technique [0002] In recent years, the wide application of the Internet has made the business process design of the workflow system an important technology for various organizations and enterprises. A well-running system must not only ensure the integrity and fluency of its functions, meet the needs of users for functions, and prevent the system from crashing and freezing due to various operations by users, but also avoid system failure during operation due to The correctness of the data itself (abnormal data, tampered with) caused the security issue of damage to the interests of both participants. Therefore, a correct workflow system should not only consider the logical structure, but also pay more attention to ...
