Abstract: An α-algorithm based process mining algorithm is proposed to solve the problem of mining incomplete process logs.Based on the order relations defined by the α-algorithm，this algorithm proposes a set of rules which can deduce implicit parallel relations out of known order relations.It can construct the process’s structural model using these relations.As demonstrated by extensive experimental results，the proposed algorithm is more effective than traditional α series algorithms to mine incomplete process logs.
