| 3. If total demand and total supply are not equal then the problem is said to be unbalanced. | 3. If the number of rows is not equal to the number of columns then problems are unbalanced. |
What is transportation and assignment models?
The transportation model is concerned with selecting the routes between supply and demand points in order to minimize costs of transportation subject to constraints of supply at any supply point and demand at any demand point. …
What is transportation and assignment?
The Transportation and Assignment problems deal with assigning sources and jobs to destinations and machines. The constraints are the ones imposed by the number of cars to be transported from each plant and the number each center can absorb.
What is the differences between transportation and transshipment models?
A transportation problem allows only shipments that go directly from supply points to demand points. points or between demand points. Sometimes there may also be points (called transshipment points) through which goods can be transshipped on their journey from a supply point to a demand point.

| The rows and columns may have any number of allocations depending on the rim conditions. | The rows and columns must have one-to-one allocation. Because of this property, the matrix must be a square matrix. |
What are the transportation models?
The transportation model addresses the concept of moving a thing from one place to another without change. It assumes that any damage en route has negative consequences, and so it’s used to analyze transportation systems and find the most efficient route for resource allocation.
