What are the methods to solve transportation problem?
We present the three methods and an illustrative example is solved by these three methods.
- North- West Corner Method.
- Minimum-Cost Method.
- Vogel’s Approximation Method (VAM)
- ILLUSTRATIVE EXAMPLE.
- North West-Corner method.
What is CIJ in transportation problem?
Cij = unit cost of transportation from source Si to destination Dj .
What is north west corner method?
Definition: The North-West Corner Rule is a method adopted to compute the initial feasible solution of the transportation problem. The name North-west corner is given to this method because the basic variables are selected from the extreme left corner. The transportation costs are also given in the matrix.
What is transportation problem write the method of solving transportation problem?
Unlike many LP problems, the transportation problem is feasible to solve by hand using a series of tables and well-documented strategies such as the Northwest-Corner Method to find an initial basic feasible solution and then using techniques like the Least-Cost Method or the Stepping Stone Method.
What is basic solution in transportation problem?
A feasible solution to a transportation problem is said to be a basic solution if it contains no more than m+ n-1 non-negative allocations, where m is the number of rows and n is the number of columns of the transportation problem.
How is CIJ calculated in transportation problem?
Determine a set of m + n numbers ui,i = 1,…,m and vj,j = 1,…,n such that in each cell (i, j) cij = ui + vj. Step 3. Calculate cell evaluations (unit cost difference) dij for each empty cell (i, j) by using formula dij = cij − (ui + vj). Step 4.
What is unbalanced transportation?
Unbalanced transportation problem is a transportation problem where the total availability at the origins is not equal to the total requirements at the destinations.
How do you find north west corners?
Sub-directions in Vastu – How to Identify Them
- The place where the North and East sides meet is the North-East corner.
- The point at which the South and East sides meet is the South-East corner.
- The corner where South and West meet is the South-West corner and.
- North-West corner is the one where West meets North.
WHAT IS AN transportation problem?
The transportation problem is a special type of linear programming problem where the objetive consists in minimizing transportation cost of a given commodity from a number of sources or origins (e.g. factory, manufacturing facility) to a number of destinations (e.g. warehouse, store).
What is initial basic solution?
The initial basic feasible solution (IBFS) is a significant step to achieve the minimal total cost (optimal solution) of the transportation problem. It reached its optimal solution for thirty-one of thirty-five numerical examples (88.57%).

Which is the best description of a transportation problem?
What is a Transportation Problem?• The transportation problem is a special type of LPP where the objective is to minimize the cost of distributing a product from a number of sources or origins to a number of destinations.• Because of its special structure the usual simplex method is not suitable for solving transportation…
How is the transportation problem used in Supply Chain Engineering?
There is no other possible combination of variables that will lead to a lower transportation cost. The transportation problem represents a particular type of linear programming problem used for allocating resources in an optimal way; it is a highly useful tool for managers and supply chain engineers for optimizing costs.
