How do you solve an unbalanced transportation problem?
These unbalanced problems can be easily solved by introducing dummy sources and dummy destinations. If the total supply is greater than the total demand, a dummy destination (dummy column) with demand equal to the supply surplus is added.
What is balanced transportation problem give an example?
For example, in case the total production of 4 factories is 1000 units and total requirements of 4 warehouses is also 1000 units, the transportation problem is said to be a balanced one.
What is an unbalanced transportation problem how do we start in this case?
UNBALANCED TRANSPORTATION PROBLEM : A transportation problem is said to be unbalanced if the supply and demand are not equal. Two situations are possible:- 1. If Supply < demand, a dummy supply variable is introduced in the equation to make it equal to demand.
What is unbalanced transportation problem?
Unbalanced transportation problem is a transportation problem where the total availability at the origins is not equal to the total requirements at the destinations.
What variable is used to balance an unbalanced transportation problem?
What is unbalanced problem in transportation?
What is meant by unbalanced problem?
What is Unbalanced Problem? Unbalanced problems are typically encountered in transportation problems in operations research where the total supply does not equal the total demand. But in reality, the problems that we encounter involve unbalanced conditions where the supply and demand are not equal.
What is unbalanced transportation?
When is a transportation problem said to be unbalanced?
UNBALANCED TRANSPORTATION PROBLEM : A transportation problem is said to be unbalanced if the supply and demand are not equal. Two situations are possible:- 1. If Supply < demand, a dummy supply variable is introduced in the equation to make it equal to demand.
How is the transportation problem an extension of linear programming?
The transportation problem is an extension of linear programming technique because the transportation costs are formulated as a linear function to the supply capacity and demand. Transportation problem exists in two forms.
When is a transportation problem a solvable problem?
In general, if a transportation problem has m rows an n columns, then the problem is solvable if there are exactly (m + n –1) basic variables 7. . UNBALANCED TRANSPORTATION PROBLEM : A transportation problem is said to be unbalanced if the supply and demand are not equal. Two situations are possible:- 1.
Can a transportation problem be formulated as a LPP?
The unit cost is independent of the number of goods transported. The objective is to minimize the total transportation cost. Although transportation problems can be formulated as a LPP, other easier algorithms are developed for solving them. 1. Formulation of the transportation model in LPP
