Problems solved by technology

[0004] Existing model repair methods are mainly based on model calibration to discover the deviation between the log and the model to achieve the purpose of model repair, in which the model calibration is to replay the track in the log to the model, and then discover the gap between the model and the real business. The model repair method based on model calibration has certain guiding and reference significance for model repair, but in the process of repairing the big data transaction model, in the case of log and model fitting, when multiple parallel branches in the transaction model When there is...

[0084] 1. Related concepts

[0085] 1.1, multiset, sequence

[0086] is a collection, there is a mapping in representative set The set of all multisets on ; for example multiset B 1 :=[],B 2 :=[a],B 3 :=[a,b,b,c,b,a],B 4 :=[a 2 ,c,b,b 2 ];sequence |σ| represents the length of the sequence σ, |σ|:=n.

[0087] 1.2. Petri net

[0088] Petri net is a model used to describe distributed systems; the triple N:=(P,T,F) is called a Petri net, P, T are two disjoint finite sets, they are the network N The basic element set, P is called the place set, T is called the transition set, and F is the flow relationship of the network N.

[0089] Let N:=(P,T,F) be a Petri net, for x∈P∪T, record

Abstract

The invention discloses a deviation reduction-based big data transaction model analysis and restoration method, and belongs to the field of business process management. The method specifically comprises the following steps of discovering a deviation set Rd between event logs and a model through a reachable marking graph-based deviation discovery method; and according to the deviation set Rd, obtaining an adjacent side relationship difference set Rp, and obtaining an adjacent side relationship difference sequence set PS. Through the deviation reduction-based model restoration method, effectivedeviation-based model restoration is realized; and a restoration result is subjected to model fitting degree, accuracy, conciseness and time complexity assessment to verify the validity of the method.

Description

technical field [0001] The invention belongs to the field of business process management, and in particular relates to a big data transaction model analysis and repair method based on deviation reduction. Background technique [0002] With the emergence of massive data, the value of data has been recognized by more and more industries and fields. Big data transactions have become a new type of data circulation means. During the construction of big data trading platforms, self-owned data sales, data processing Various transaction modes such as resale and data transaction platform services. How to discover and solve the deviation between actual execution and business rules in the big data transaction process in time is a huge challenge for the big data transaction process. Business process management realizes the comprehensive management of the integration of various business links by modeling, managing, monitoring and optimizing the entire life cycle of business processes. ...
