What is transportation problem with example?

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 degeneracy in transportation problem with example?

Degeneracy in Transportation Problem in Operational Research. If the number of allocations is short of the required number, then the solution is said to be degenerate. If number of allocations, N = m + n – 1, then degeneracy does not exist.

What is looping in transportation problem?

Loop Pivoting. Loop is an ordered sequence of at least four different cells that satisfy all three conditions: Any two consecutive cells lie in either the same row or same column. No three or more consecutive cells lie in the same row or column. The last cell is in the same row or column as the first cell.

Which method is best for transportation problem?

VAM is the best solution method but degeneracy is a major issue in transportation problem. In a standard transportation problem with m sources of supply and n demand , any feasible solution requires allocations in m + n – 1 independent cells.

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 the aim of transportation problem?

The transportation problem is a special type of linear programming problem where the objective is to minimise 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 problems.

How do you introduce Epsilon in transportation problem?

Rule: ADVERTISEMENTS: This extremely small quantity is denoted by a Greek letter e (epsilon) or A (delta). In a minimization problem it is better to allocate Δ to unoccupied cells that have lowest transportation cost, whereas in maximization problem it should be allocated to a cell that has a high payoff value.

When a transportation problem is said to be balanced?

Transportation Problems. If the total demand is greater than the total supply, then problem is infeasible. If the total demand is equal to the total supply, the problem is said to be a balanced transportation problem.

Which is an example of a transportation problem?

TRANSPORTATION PROBLEMS Transportation problem example A mining company extracts gravel, the basic product it sells, from three mines, L1, L2 and L3. The weekly production of each mine is 75, 150 and 75 tones of gravel respectively.

What is the problem of Transportation and transshipment?

The transportation problem involves the determination of the amount of goods that have to be transported from a number of sources to a number of destinations. The most usual objective is to minimize the total shipping costs or the total distances that have to be traveled for the transportation of the goods.

How is a transportation problem a linear problem?

 Transportation problem is a specific case of Linear Programming problems and a special algorithm has been developed to solve it. The problem: Given needs at the demand locations, how should we take the limited supply at supply locations and move the goods. The objective is to minimize the total transportation cost. 6 TRANSPORTATION PROBLEMS

Is it possible to solve a transportation problem by hand?

Problems of this type, containing thousands of variables and constraints, can be solved in only a few seconds on a computer. In fact, we can solve a relatively large transportation problem by hand. There are some requirements for placing an LP problem into the transportation problem category.
