example 1
[0197] Example 1: The original process model PN of a certain business process 1 Such as figure 2 shown.
[0198] event logL 1 ={σ 1 ,σ 2 ,σ 3 ,σ 4 ,σ 5 ,σ 6 ,σ 7 ,σ 8 ,σ 9 ,σ 10 ,σ 11 ,σ 12}={,,,,,,, ,,,, }.
[0199] The order relationship based on extension is listed below, and the log order set and model order set are obtained.
[0200] right The following extended order relationship can be obtained:
[0201] (1) follow relationship >:
[0202] σ 1 >={a>b, b>e, e>g};
[0203] σ 2 >={a>c,c>f,f>g};
[0204] σ 3 >={a>d,d>g};
[0205] σ 4 >={a>b, b>e, e>c, c>f, f>g};
[0206] σ 5 >={a>b, b>c, c>e, e>f, f>g};
[0207] σ 6 >={a>b, b>c, c>f, f>e, e>g};
[0208] σ 7 >={a>c,c>b,b>e,e>f,f>g};
[0209] σ 8 >={a>c,c>b,b>f,f>e,e>g};
[0210] σ 9 >={a>c,c>f,f>b,b>e,e>g};
[0211] σ 10 >={a>b,b>e,e>d,d>g};
[0212] σ 11 >={a>b, b>d, d>e, e>g};
[0213] σ 12 >={a>d, d>b, b>e, e>g};
[0214] R={a>b, a>c, a>d, b>e, b>c, c>b, b>d, d>b, b>f, f>b, c>e,...
example 2
[0265] Example 2: According to Example 1, there is R L1 ={a→b, b→e, e→g, a→c, c→f, f→g, a→d, d→g, c×d, d×f, b∨c, b∨d, b∨f,c∨e,d∨e,e∨f}, R M1 ={a→b, b→e, e→g, a→c, c→f, f→g, a→d, d→g, b×c, b×d, b×f, c×d, c×e,d×e,e×f}. By comparing R L1 and R M1 , the deviation set obtained by method 2 is as follows:
[0266] R D1={b∨c|b×c,b∨d|b×d,b∨f|b×f,c∨e|c×e,d∨e|d×e,e∨f|e×f} .
[0267] Step II: repair the corresponding sequential structure or selection structure into a concurrent structure based on the deviation set, and complete the repair of the model.
[0268] With the update of the business process system, the original process model has not been updated in time, making it inconsistent with the actual business process, so the new event log reflected in the process cannot be reproduced correctly.
[0269] If the sequence relationship among certain activities in the event log cannot be described by the corresponding sub-model, it is necessary to replace the original sub-model with...
example 3
[0290] Example 3: The original process model PN of a certain business process 1 Such as figure 2 shown.
[0291] Log L 1 ={σ 1 ,σ 2 ,σ 3 ,σ 4 ,σ 5 ,σ 6 ,σ 7 ,σ 8 ,σ 9 ,σ 10 ,σ 11 ,σ 12}={,,,,,,, ,,,, }.
[0292] The process of repairing the model according to Method 3 is as follows:
[0293] From method 3 we know that R D1 ={b∨c|b×c,b∨d|b×d,b∨f|b×f,c∨e|c×e,d∨e|d×e,e∨f|e×f} , and R D1 ′={b∨c|b×c, b∨d|b×d, d∨e|d×e, e∨f|e×f}. For b∨c|b×c∈R D1 ',Have because R D1 (b)>R D1 (c), so t 1 =b,t 2 = c. At this time t o = · ( · t 1 )∩ · ( · t 2 ) = a is seen as a logical output transition. new place p 7 The previous set as b is added to P. next step will p 2 arcs between b and b are removed, and the arcs from a to p are added respectively 7 and from p 7 to the two arcs of b.
[0294] According to the existing mining algorithm, the logical output expression of transition a is O′(a)=p 2 ∨p 7 . For d∨e|d×e∈R D1 ',Have due to R D1 (e)>R D1 (d)...
