In this research, a multi-objective linear mathematical model for scheduling university courses is presented. The objective function of this research includes three functions as minimizing the total of the difference between the beginning and end of classes per day for different groups of students, maximizing the usefulness of presenting courses and minimizing the number of courses that the distance of their sessions is less than one day. The restrictions include restrictions on the non-interference of professors, classes, and students' curricula, as well as restrictions on how different courses are presented. In the proposed model, the method of presenting three-unit courses with a two-week period is considered. Finally, the performance of the proposed model using GAMS software is shown for a real example. %> http://jamlu.liau.ac.ir/article-1-1852-en.pdf %P 15-30 %& 15 %! %9 Applicable %L A-11-1647-1 %+ Department of Mathematics and Applications, Kosar University of Bojnord, Bojnord, Iran %G eng %@ 2251-7286 %[ 2021
