Introduction

Scheduling lecture activities in tertiary institutions is a complex process that often encounters various obstacles. This is caused by frequent clashes between course schedules, lecturers, and classrooms. This problem can result in an inefficient allocation of courses and reduce the quality of student learning experiences. Therefore, it is essential to have effective systems and optimization methods for compiling lecture schedules. In this context, this study aims to help the manager schedule in preparing scheduling courses effectively.

The Importance of Effective Lecture Scheduling

Effective lecture scheduling is crucial for the success of tertiary institutions. It ensures that courses are allocated efficiently, reducing conflicts between lecturers, classrooms, and students. This, in turn, improves the quality of education, enhances student learning experiences, and optimizes resource use. However, traditional scheduling methods often rely on manual allocation, which can lead to inefficiencies and conflicts.

The Neighborhood Search Method

The Neighborhood Search method is a sophisticated optimization technique that includes several algorithms, such as genetic algorithms, simulated annealing, and taboo search. These methods have unique strengths and characteristics that allow scheduling to be more optimal and free from conflict. In this study, we will explore the application of the Neighborhood Search method in optimizing lecturer lecture schedules.

Analysis of the Neighborhood Search Method

Genetic Algorithm

Genetic algorithms adopt the principles of natural selection in the evolutionary process. By using the population of existing solutions, this algorithm carries out variations and selection to produce a better solution from generation to generation. In the context of scheduling, this algorithm can be used to identify the most efficient schedule combination by considering various parameters, such as the availability of lecturers, classrooms, and student preferences.

Genetic algorithms work by:

Initialization: Creating an initial population of solutions
Selection: Selecting the fittest solutions based on their fitness function
Crossover: Combining the selected solutions to create new offspring
Mutation: Introducing random changes to the offspring to increase diversity
Replacement: Replacing the least fit solutions with the new offspring

Simulated Annealing

Simulated Annealing is an optimization method inspired by the physical process of Annealing in metallurgy. This process involves heating and cooling to achieve optimal conditions. In scheduling, this method makes it possible to explore various solutions by starting from the existing schedule, then making a gradual modification. With this approach, the resulting solution can be closer to optimal, although there is a possibility of a decrease in each step.

Simulated Annealing works by:

Initialization: Creating an initial solution
Temperature: Setting an initial temperature
Iteration: Iteratively modifying the solution and accepting or rejecting the new solution based on the temperature
Cooling: Gradually reducing the temperature to converge to the optimal solution

Taboo Search

Taboo Search is a method designed to avoid getting caught up in local solutions. By creating a list of taboo from the steps taken previously, this method ensures that the same solution is not re-elected in the search process. In scheduling, this is very important to ensure that the scheduled team can continue to find new solutions that are better without being trapped in repeated patterns.

Taboo Search works by:

Initialization: Creating an initial solution
Taboo List: Maintaining a list of solutions that have been visited previously
Iteration: Iteratively modifying the solution and checking if it is on the taboo list
Update: Updating the taboo list to prevent revisiting the same solution

Benefits of Schedule Optimization

By implementing the Neighborhood Search method in lecture scheduling, universities can achieve several benefits, including:

Time Efficiency: Better schedule management reduces the time needed to arrange and adjust the schedule.
Improving the Quality of Education: Regular schedules and no clashes allow lecturers to teach better, and improve student learning experiences.
Optimal Resource Use: With the right scheduling, the use of classrooms and teaching time can be more efficient, reducing operational costs.

Conclusion

Research on lecture scheduling optimization using the Neighborhood Search method is not only an academic contribution but also has a practical impact on the management of education in tertiary institutions. The application of this method is expected to increase the effectiveness of scheduling so that all parties involved, both lecturers, students, and administration, can feel the benefits. By adopting the Neighborhood Search method, universities can improve the quality of education, optimize resource use, and enhance the overall learning experience for students.

Future Research Directions
