Introduction

Tutor scheduling is a complex task that requires careful consideration of various factors, including student needs, tutor availability, and institutional management policies. Traditional linear programming methods often focus on a single goal, such as maximizing profit or minimizing costs, but in reality, there are often multiple goals that must be considered together. This is where the goal programming model comes in, offering a more flexible approach to achieve optimal solutions that balance the interests of tutors and institutions.

What is Goal Programming?

Goal programming is a development of linear programming that has several goals at once. This method serves to minimize the deviation between the desired level of purpose and the actual achievement. The process is carried out by changing inequality into equality by including positive and negative deviation variables. In this way, the achievements below or above each target can be accommodated.

Basic Concepts of Goal Programming

Goal programming offers a more flexible approach compared to traditional linear programming. In linear programming, we usually only focus on one goal, such as maximizing profit or minimizing costs. However, in reality, there are often several goals that must be considered together. For example, in the context of tutor scheduling, there are several factors that must be considered:

Student needs: Students have different learning needs, and tutors must be scheduled to meet these needs.
Availability of tutors: Tutors have different time availability, and their schedules must be taken into account.
Institutional management policies: Institutions have their own policies and procedures that must be followed when scheduling tutors.

By using goal programming, we can get optimal solutions that not only take into account one goal, but also accommodate other goals. This is important to create a balance between the interests of tutors and institutions. This model helps in establishing priorities and provides guidance for better decision making.

Application in Tutor Scheduling

In the context of tutor scheduling, goal programming can be used to determine the schedule that meets all existing needs. For example, if there are a number of tutors with different time availability and a number of students with various learning needs, this model will help in preparing optimal schedules. In addition, this model also ensures that all goals, such as the fulfillment of the number of sessions per week, the distribution of fair workloads between tutors, as well as student satisfaction, can be achieved simultaneously.

One of the advantages of this model is its ability to deal with uncertainty and variables that change. In practice, conditions such as the availability of tutors can change suddenly, and students may have different preferences. By adding the deviation variable, this model is able to provide the flexibility needed to adjust these changes without sacrificing the main objectives.

Benefits of Goal Programming in Tutor Scheduling

The goal programming model offers several benefits in the context of tutor scheduling, including:

Optimal solutions: The model provides optimal solutions that balance the interests of tutors and institutions.
Flexibility: The model is able to deal with uncertainty and variables that change.
Improved decision making: The model helps in establishing priorities and provides guidance for better decision making.
Increased harmony and justice: The model contributes to increasing harmony and justice between tutors and institutional management.

Conclusion

The results of the application of the goal programming model in scheduling tutors provide optimal solutions, where all objective functions can be achieved. In addition, this model contributes to increasing harmony and justice between tutors and institutional management. With a structured and systematic approach, Goal Programming provides effective tools for human resource management, especially in the context of education. Therefore, the use of this model is highly recommended for institutions that want to increase efficiency and satisfaction in the tutor scheduling process.
