Abnormal fragment extraction method for workflow net inspection, readable storage medium and terminal

Abstract

The invention provides an abnormal fragment extraction method for workflow net inspection, which comprises the following steps: a model initial WFD network is constructed and data constraints are generated; according to the data constraint, the corresponding constraint analysis mode, the corresponding relationship between the data and the positive and negative constraint, and the corresponding relationship between the constraint and the guard function value are constructed; a WFDC network model is generated; a reachable configuration CDC graph with data constraints is generated; according to the characteristics of WFDC network, the multi-layer rationality of WFDC network is defined; according to the WFDC network model and the multi-level rationality, the detection result is obtained by judging the rationality level of the network model; when the detection result is error, the reachable configuration CDC map is converted into a minimum complete CDC tree, and an abnormal path in which error state exists is extracted; according to the extracted abnormal paths and data constraint features, the abnormal segments of the abnormal paths are extracted. The invention solves the problem of automatically detecting abnormal fragments in the case of detection result failure of the system in the prior art.

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 ...

Problems solved by technology

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a method for extracting abnormal fragments of workflow network inspection, a readable storage medium and a terminal, which are used to solve the problem that the value of the data of the exile of work in the prior art is Data abnormalities caused by tampering or misoperation, and the corresponding abnormal fragments cannot be accurately obtained
