Abstarct: Managing business processes include programming simulation and analysis of a business system. Nowadays information technology leans toward workflow management. This is a computer system which focuses on defining and managing activities in an organization to reach a certain goal. The concept of process model is used to simulate the workflow system. Making a process model from logging is one of the important ground works in business process management. This thesis is going to use educational processes as a Process-aware system in Bachelor’s and master’s levels in Shahrood University then we use time patterns in process. Next stage is recording demands of the students in Golestan system that is baxsed on the time difference (day) between the approval of request by the student, Department head, Dean of school and the office of educational services, thenceforth the best mathematical distribution data is counted. Finally turnaround times for requests and structural change of educational processes can be reduced by defining mathematical distributions.
