The assignment problem is a special case of the transportation problem, which in turn is a special case of the min-cost flow problem, so it can be solved using algorithms that solve the more general cases. Also, our problem is a special case of binary integer linear programming problem (which is NP-hard). But, due to the specifics of the ...

Operations Research/Transportation and Assignment Problem
The Transportation and Assignment problems deal with assigning sources and jobs to destinations and machines. We will discuss the transportation problem first. Suppose a company has m factories where it manufactures its product and n outlets from where the product is sold. Transporting the product from a factory to an outlet costs some money ...

Solving an Assignment Problem
The following code creates the objective function for the problem. Python C++ Java C#. objective_terms = [] for i in range(num_workers): for j in range(num_tasks): objective_terms.append(costs[i][j] * x[i, j]) solver.Minimize(solver.Sum(objective_terms)) The value of the objective function is the total cost over all variables that are assigned ...
PDF Transportation, Assignment, and Transshipment Problems
Transportation, Assignment, and Transshipment Problems In this chapter, we discuss three special types of linear programming problems: transporta-tion, assignment, and transshipment. Each of these can be solved by the simplex algorithm, but specialized algorithms for each type of problem are much more efficient. 7.1 Formulating Transportation ...
Algorithms: The Assignment Problem
The usual name for this is optimization. An optimization problem is one where we have an "objective function" (which tells us what our goals are) and one or more "constraint functions" (which tell us what the rules are). The classic example is a factory that can make both "widgets" and "gadgets".
Chapter 5: Assignment Problem
5.1 INTRODUCTION. The assignment problem is one of the special type of transportation problem for which more efficient (less-time consuming) solution method has been devised by KUHN (1956) and FLOOD (1956). The justification of the steps leading to the solution is based on theorems proved by Hungarian mathematicians KONEIG (1950) and EGERVARY ...
Is there a greedy algorithm to solve the assignment problem?
The answer of your post question (already given in Yuval comment) is that there is no greedy techniques providing you the optimal answer to an assignment problem. The commonly used solution is the Hungarian algorithm, see. Harold W. Kuhn, "The Hungarian Method for the assignment problem", Naval Research Logistics Quarterly, 2: 83-97, 1955.
The Transportation problem
There is a cost to transport goods from a factory to a warehouse. Find the transportation of good from factory → warehouse that has the lowest possible cost. Example: Factories: A 1 makes 5 ... The Transportation problem is closely related to the assignment problem (it is in fact easier than the assignment problem)
Transportation problems and their solutions: literature review
The assignment problem This problem is a combinatorial optimization problem that deals with allocating a set of resources (eg workers, machines, vehicles) to a set of tasks (e.g. tasks, projects) in such a way as to minimize the total cost. or maximize total profit. The problem can be formulated as a linear program and can also be considered a ...
Solving assignment problem with lpSolve in R
The assignment problem is a classic problem in linear program.If, for example, you have n jobs that need to be manufactured during the upcoming shift (in a manufacturing plant) and you have m machines to produce these tasks, then you want to assign the jobs to machines in an optimal way.In this say you might want to reduce the manufacturing costs incurred, hence you want to find the cost ...
Assignment problem with multiple workers for each job
This problem is a special case of the b-matching problem, and hence can be solved in polynomial time. Extensive information on b-matchings can be found for instance in the book: László Lovász and Michael D. Plummer: Matching Theory ISBN-10: -8218-4759-7 ISBN-13: 978--8218-4759-6

PDF Chapter 5: Linear Programming: Transportation and Assignment Models
5.1 TRANSPORTATION MODELS. The transportation model is a special class of linear programming that deals with shipping a commodity from sources/origins (e.g Factory) to Destinations (e.g Warehouses). Each origin represents a source of supply for the commodity; each destination represents a point of Demand for the commodity.

Transportation Problem, Linear Programming
The transportation problem deals with a special class of linear programming problems in which the objective is to transport a homogeneous product manufactured at several plants (origins) to a number of different destinations at a minimum total cost. The total supply available at the origin and the total quantity demanded by the destinations are given in the statement of the problem.
