                                        audit performance and assignments, which is a finding that echoes current research
                                        findings (Asare and McDaniel, 1996; Tan, Ng, and Mak, 2002; Alissa et al., 2014).
                                             Machine learning methods can improve the ability of audit-task scheduling model

                                        assignment of auditing tasks could be summarized as dispatching rules. Thus, in the

                                        future,  audit  supervisors  will  be  able  to  follow  the  audit  dispatch  rules  for  task

                                        assignment, and the encouragement of learning in organization will also have a positive


                                        effect. For example, priority should be given to assigning auditors with professional
