## What is Degeneracy in a Transportation problem?

When number of allocations is less then (m + n – 1), an infinitely small allocation called epsilon is added to eliminate the degeneracy. This epsilon is added to an empty cell in the degenerate matrix which is independent with minimum cost. If number of allocations is greater then (m +...

## What is Sensitivity Analysis in a Transportation Problem?

When a solution is obtained its ability to remain optimal when external environment changes is tested in sensitivity analysis. The obtained solution is subjected to sensitivity analysis to determine its sensitivity it changes.

## What is Test for Optimality in Transportation Problem?

Optimally test in a transmission problem is carried out on a non-degenerate initial feasible solution to ascertain if the IFS obtained is optimal. Optimally test in a TP is carried out by determining the opportunity costs of all empty cells in a transportation matrix. Nature of the opportunity cost indicates the optimality....

## Explain Independent cells in a Transportation Problem.

(i) Independent cells are those which do not form a closed loop with other occupied cells.   (ii) An infinitesimally allocation i.e. epsilon is added to an empty independent cell which carries lowest transportation cost to eliminate degeneracy.

## What is Prohibited Transportation Problem?

Prohibited transportation problem:   ‘Allocations to minimum cost route’ is the principle which prevents allocation to prohibited routes when we designate “M’ (maximum cost) to the prohibited route. In many practical solutions, some of the routes in a transportation are prohibited due to certain operational problems such as flood situation, road conditions,...

## What is Unbalanced Transportation Problem?

(i) When supply capacity of sources and requirement (demand) of destinations do not match a transportation problem is said to be unbalanced. An unbalanced problem can not be processed.   (ii) To eliminate imbalance, a dummy source or destination is created and shortfall in terms of supply or demand is allocated to dummy.

## How to solve Transportation Problems?

TRANSPORTATION PROBLEMS Advertisement   Introduction: A Transportation problem is Supply and Demand problem. There are some supply centres e. g. plants. And there are some demand centres e. g. warehouses or distribution centres. Supply at each plant is given. Demand at each warehouse is given. And unit cost of...

## How to solve Assignment Problems?

ASSIGNMENT PROBLEMS   Introduction: An Assignment problem involves assignment or matching of two things. E. g. matching of workers and jobs or matching of salesmen and areas etc. The basic principle in Assignment problem is that the matching is on a one to one basis. i. e. One worker...
