Difference between transportation and assignment problems?
The transportation problem is concerned with finding the optimal way to transport goods from sources to destinations, while the assignment problem is concerned with finding the optimal way to assign agents to tasks. Both problems are important in operations research and have numerous practical applications.

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.
Transportation and Related Problems
Transportation and Related Problems. In this section, we will discuss several special types of linear programs. These are the transportation problems, the assignment problems, and the transshipment problems.

Transportation Problem
Transportation problem is a special kind of Linear Programming Problem (LPP) in which goods are transported from a set of sources to a set of destinations subject to the supply and demand of the sources and destination respectively such that the total cost of transportation is minimized. It is also sometimes called as Hitchcock problem. Types of Transportation problems:
Transportation and Assignment Problems
Abstract. Transportation and assignment problems are traditional examples of linear programming problems. Although these problems are solvable by using the techniques of Chapters 2-4 directly, the solution procedure is cumbersome; hence, we develop much more efficient algorithms for handling these problems.
PDF Transportation, and Assignment Problems
Transportation Problem •To solve the transportation problem by its special purpose algorithm, it is required that the sum of the supplies at the sources equal the sum of the demands at the destinations. If the total supply is greater than the total demand, a dummy destination is added with demand equal to the excess supply, and shipping costs

What is the difference between Assignment Problem and Transportation
The assignment problem is said to be balanced if it is a _____. Choose the correct alternative : In an assignment problem if number of rows is greater than number of columns then. The objective of an assignment problem is to assign _____. Fill in the blank : When an assignment problem has more than one solution, then it is _____ optimal solution.
Traffic Assignment Problem
Traffic assignment considers which paths are to be selected and the amount of traffic using these paths (if more than one unit). For simple problems, a single path will be selected, while for complex problems, several paths could be used. Factors behind the choice of traffic assignment may include cost, time, or the number of connections.
Balanced and Unbalanced Transportation Problems
Unbalanced Transportation Problem. Unbalanced transportation problem is defined as a situation in which supply and demand are not equal. A dummy row or a dummy column is added to this type of problem, depending on the necessity, to make it a balanced problem. The problem can then be addressed in the same way as the balanced problem.
Difference Between Assignment and Transportation Model
The problem may have a rectangular matrix or a square matrix. The assignment algorithm can not be used to solve the transportation model. The rows and columns may have any number of allocations depending on the rim conditions.
