“…There are a limited number of papers on planning university exams, including [26], [27], [28], [29] and [30]. In these papers, more attention has been paid to the method of model solving and no new innovation has been presented regarding the modeling problem, while the main innovation of this paper is the presentation of a new model in this regard.…”

This research is an attempt to create optimized planning in educational units. The problem of university courses timetabling is one of the problems that is very important for educational units; establishing optimal distances to comply with students' study status as well as balancing other constraints of the timetabling problem is one of the challenges in a timetabling problem. Therefore, sometimes an educational unit may not be able to strike a good balance between all the constraints it faces and fail to achieve a proper timing table. In this paper, in order to achieve optimal exam timetabling with an integer scheduling approach, a model for exam timetabling is presented. The purpose of the proposed mathematical model is to maximize the appropriate time intervals that should be established between students' exams. In this mathematical model, according to the number of allowed exam days and the number of possible exam sessions per day, a number of positions have been considered and it is tried to assign these positions to the courses according to the courses related to the students of each entrance. The most important advantage of the proposed model is its simplicity while sufficient accuracy. Therefore, complex methods are not needed to solve this model.

“…Another representation of the scheduling problem was studied at Masdar Institute (MI), which revealed that some constraints should be added to the common constraints found in the student component, namely limited room, specific examiner requests, and the number of exams scheduled for one student in a certain period. The model was formulated using integer programming (IP) and solved using Lingo software for model optimization [4] [5].…”

The Nursing Undergraduate Study Program of the Vocational Faculty of Universitas Airlangga has two classes in two different cities: Gresik and Lamongan. The final project examination scheduling in the study program should be scheduled simultaneously to minimize the round-trip of the examiner. Currently, the scheduling process is done manually without a certain systematic method or approach. In this paper, an optimization model is developed to solve the scheduling problem. Several factors are considered in the model, namely the number of examiners, examination room availability, and the home campus of eachexaminer. The model employed an integer programming approach with the objective function of maximizing the totalassignment of the examiners in the time slot. The model cansolve the scheduling problem more efficiently than manual scheduling.

“…The examination timetabling literature, especially cases, introduces a variety of examination policy practices that aim to provide resource efficiency, also to reduce the students’ exam anxiety and satisfy the invigilators. To minimize the exam anxiety, many studies restrict the frequency of the exams that students will take in a certain time window (Muklason et al , 2017) such as one or two exams per day (Hassan and Hassan, 2016; Selemani et al , 2013), one exam per two days (Abou Kasm et al , 2019). In settings with more than one exam per day, at least one time slot is left empty between exams (Leite et al , 2019).…”

“…Acceptance of on/off requests based on specific days, time slots, exam rooms, etc. from stakeholders may prevent more efficient use of resources (Abou Kasm et al , 2019). If the resources are not increased in proportion to demand, the balance will be distorted against students and invigilators.…”

Purpose The study has two main objectives. The first is to introduce three new examination policy practices: overbooked exam rooms, a substitute invigilator and an inheritance of the invigilation distribution. The second is the use of the examination model to determine the sustainability of the system against expected changes and to obtain long-term strategic information. This study aims to obtain managerial insights on the sustainability of the examination system with the newly introduced practices; it does not claim to propose solutions for large-scale problems. Design/methodology/approach This study introduces a multi-objective mathematical model that contains a couple of constraints that belong to new practices. To check the sustainability of the system, this study gets help from sensitivity analysis, which informs the decision-maker about how the results will react to parameter changes. The authors perform all experiments in the Python/Gurobi modeling environment. Findings The results demonstrate that the proposed practices are effective in the efficient use of resources. Also, this study shows that the examination model can be used as a stress test so that the weaknesses of the system can be identified and long-term strategic information can be obtained. Originality/value The contribution of this study is twofold: the introduction of examination policy practices that are overbooked exam rooms, a substitute invigilator and an inheritance of the invigilation distribution. Overbooked exam rooms aim to use resources effectively, taking into account the possibility of temporarily increasing the exam room capacity. The substitute invigilator protects the examination process against sudden events. The inheritance of the invigilation distribution helps to ensure fairness; and the use of the examination model to obtain managerial insights on expectations. This allows testing the validity of existing policies and making necessary changes, taking into account possible changes in the system. In this respect, it differs from the studies in the literature and fills an important managerial gap.
