lets understand the Difference between transportation and assignment problems?
Transportation problems and assignment problems are two types of linear programming problems that arise in different applications.
The main difference between transportation and assignment problems is in the nature of the decision variables and the constraints.

Additional Different between Transportation and Assignment Problems are as follows :
Decision Variables:
In a transportation problem, the decision variables represent the flow of goods from sources to destinations. Each variable represents the quantity of goods transported from a source to a destination.
In contrast, in an assignment problem, the decision variables represent the assignment of agents to tasks. Each variable represents whether an agent is assigned to a particular task or not.
Constraints:
In a transportation problem, the constraints ensure that the supply from each source matches the demand at each destination and that the total flow of goods does not exceed the capacity of each source and destination.
In contrast, in an assignment problem, the constraints ensure that each task is assigned to exactly one agent and that each agent is assigned to at most one task.
Objective function:
The objective function in a transportation problem typically involves minimizing the total cost of transportation or maximizing the total profit of transportation.
In an assignment problem, the objective function typically involves minimizing the total cost or maximizing the total benefit of assigning agents to tasks.
In summary,
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.
