Abstract :The assignment process of invigilators to the exams could be difficult and time-consuming process when there are too many exam centers and the invigilator who will assign. In particular, due to the constraints of assignment according to the characteristics of the invigilators, keeping the assignment process taking into account the officer`s preferences and the fact that the test centers have a certain capacity makes the problem very complicated. In this study, the situation was considered as an assignment problem. To solve this complicated situation, we formulated the problem, with the constraints of the capacity of exam centers, type of the invigilator, type of centers and other restrictions. An algorithm for model implementation was developed and automation suitable to the algorithm was written in C# language. The model was then applied to the case of exam invigilators assignment at Open Distance Faculty of Anadolu University. All the assignment process time is reduced from weeks to several minutes.
