3. What is Transportation problem?
Transportation problems are used to find the minimum cost of transportation of
goods from m source to n destination. In this article, we will learn about
transportation problems, formulation, types and how they differ from assignment
problems.
A transportation problem is a Linear Programming Problem that deals with
identifying an optimal solution for transportation and allocating resources to
various destinations and from one site to another while keeping the
expenditure to a minimum.In simple words, the main objective of the
Transportation problem is to deliver (from the source to the destination) the
resources at the minimum
4. METHODS
Methods of solving transportation problem –
There are three ways for determining the initial basic
feasible solution they are
1.Northwest corner cell method
2. Vogel’s approximation method {VAM}
3. Least call cell method
6. TYPE OF TRANSPORTATION PROBLEM
Balanced Transportation Problem
The problem is considered to be a balanced transportation problem when both
supplies and demands are equal.
Unbalanced Transportation Problem
Unbalanced transportation problem is defined as a situation in which supply and
demand are not equal. A dummy row or a dummy column is added to this type of
problem, depending on the necessity, to make it a balanced problem. The problem
can then be addressed in the same way as the balanced problem.
7. GENERAL STRUCTURE 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
