Assignment methods show that audit experience, expertise, and task complexity affect
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
in order to analyze critical factors and understand which combinations of audit
specialties or backgrounds perform best on tasks of varying complexity. When the
number of auditors and tasks solved increases to a certain number, the order of
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
training experience in their job qualifications to the least complex tasks, and then
