Assignment Problem
19. DRAWBACK OF ASSIGNMENT PROBLEM • Assignment becomes a problem because each job requires different skills and the capacity or efficiency of each person with respect to these jobs can be different. This gives rise to cost differences. If each person is able to do all jobs equally efficiently then all costs will be the same and each job can be assigned to any person.

2. It involves assignment of people to projects, jobs to machines, workers to jobs and teachers to classes etc., while minimizing the total assignment costs. One of the important characteristics of assignment problem is that only one job (or worker) is assigned to one machine (or project). An assignment problem is a special type of linear programming problem where the objective is to minimize ...

Definition Assignment Problem is a balanced transportation problem in which all supplies and demand are equal to 1. The Hungarian Method • Find the minimum element in each row af the m x m cost matrix. Construct a new matrix by subtracting from each cost the minimum cost in its row. For the new matrix, find the minimum cost in each column.

Since the minimal number of lines is 3, an optimal assignment of zeros is possible and we are finished. Step 3. Cover all the zeros of the matrix with the minimum number of horizontal or vertical lines. Step 4. Since the minimal number of lines is less than 4, we have to proceed to Step 5.

The Assignment Problem
The assignment problem refers to a special class of linear programming problems that involve determining the most efficient assignment of people to projects, salespeople to territories, contracts to bidders, jobs to machines, and so on. The stated objective is most often to minimize total costs or time of performing the tasks at hand. One important characteristic of assignment problems is that ...

The assignment problems are a well studied topic in combinatorial optimization. These problems find numerous application in production planning, telecommunication VLSI design, economic etc. The assignment problems is a special case of Transportation problem. Depending on the objective we want to optimize, we obtain the typical assignment problems.

8.1 Introduction. An assignment problem is a particular case of transportation problem in which a number of operations are to be assigned to an equal number of operators, where each operator performs only one operation. The objective is to minimize overall cost or to maximize the overall profit for a given assignment schedule.

Assignment problem
The assignment problem is a fundamental combinatorial optimization problem. In its most general form, the problem is as follows: The problem instance has a number of agents and a number of tasks. Any agent can be assigned to perform any task, incurring some cost that may vary depending on the agent-task assignment.
