the assignment problem

The Assignment Problem: Suppose we have n resources to which we want to assign to n tasks on a one-to-one basis. Suppose also that we know the cost of assigning a given resource to a given task. We wish to find an optimal assignment–one which minimizes total cost. The model we are going to solve looks as follows in Excel. 1. To formulate this assignment problem, answer the following three questions. a. What are the decisions to be made? For this problem, we need Excel to find out which person to assign to which task (Yes=1, No=0). For example, if we assign. May 22,  · Job Assignment Problem using Branch And Bound. Let there be N workers and N jobs. Any worker can be assigned to perform any job, incurring some cost that may vary depending on the work-job assignment. It is required to perform all jobs by assigning exactly one worker to each job and exactly one job to each agent in such a way that the total /5.


Assignment Problem in Excel - Easy Excel Tutorial


Use the solver in Excel to find the assignment of persons to tasks that minimizes the total cost. What are the decisions to be made? For example, if we assign Person 1 to Task 1, cell C10 equals 1. If not, cell C10 equals 0. What are the constraints on these decisions? What is the overall measure of performance for the assignment problem decisions? The overall measure of performance is the total cost of the assignment, so the objective is to minimize this quantity.

To make the model easier to understand, name the the assignment problem ranges. Explanation: The SUM functions calculate the number of tasks assigned to a person and the number of persons assigned to a task.

Total Cost equals the sumproduct of Cost and Assignment, the assignment problem. This solution has a total cost of It is not necessary to use trial and error. We shall describe next how the Excel Solver can be used to quickly find the optimal solution. Note: can't find the Solver button? Click here to load the Solver add-in. This solution gives the minimum cost of All constraints are satisfied. Assignment Problem.

It consists of finding, in a weighted bipartite graph, a matching in which the sum of weights of the edges is as large as possible. A common variant consists of finding a minimum-weight perfect matching. May 22,  · Job Assignment Problem using Branch And Bound. Let there be N workers and N jobs.
