Formulate the Objective Function:
Define the objective function to maximize the total benefit or value. The objective function is typically a sum of the product of the assignment variables and their associated benefits from the cost matrix.
Define Decision Variables:
Identify binary decision variables representing the assignments. A value of 1 typically indicates an assignment, while 0 indicates no assignment. These variables determine the optimal solution.
Formulate Constraints:
Establish constraints to ensure that each task is assigned to exactly one individual, and each individual is assigned to exactly one task. These constraints are crucial for the problem to have a feasible solution.
Mathematical Modeling:
Develop a mathematical model that includes the objective function and constraints. This model serves as the basis for finding the optimal solution to the Maximization Assignment Problem.
Select an Optimization Method:
Choose an appropriate optimization method, such as linear programming techniques, to solve the formulated mathematical model and find the optimal assignment that maximizes the objective function.
Solve the Optimization Problem:
Apply the selected optimization method to determine the values of the decision variables that yield the optimal solution. This solution represents the most efficient assignment to maximize the total benefit or value.
Verify Feasibility:
Ensure that the obtained solution satisfies all constraints, particularly the assignment constraints. Verify that each task is assigned to exactly one individual, and each individual is assigned to exactly one task.
Evaluate Sensitivity:
Assess the sensitivity of the solution to changes in input parameters or constraints. Understand how the optimal solution varies with alterations in the cost matrix, benefits, or other variables.
