3. TATA MOTORS
Tata Motors Limited (formerly TELCO)
Is an
Indian multinational automotive manufactur
ing company
Founded in 1945 as a manufacturer
of locomotives
Tata Motors entered the passenger vehicle
market in 1991
Founder : J R D Tata
Chairman : Cyrus Mistry
4. TATA Motors launch their new SUV.
They want to supply to the major cities of
India.
They face an issue regarding production
cost.
They need to minimize their cost and
maximize their profit.
And also they want to reach their product
to all destinations with minimum
transportation distance.
5.
6. It is a particular case of transportation problem that
is in which no of operations are to be assigned to
an equal no of operators.
No of job = No of machine or operator
Matrix must be in square form,
ie, No of row = No of column
If it is a non square matrix, then add a dummy row
or dummy column to make it a square matrix.
7. Contd.
It is a type of Linear Programming Problem.
We are solving the problem by the help of
Hungarian Algorithm.
Merits.
Production manager can formulate optimal
maximum product mix.
It helps manager to improve his decision making
ability
It increases the profit and decreases the cost.
De Merits.
There may be cases of infeasibility and
unboundedness.
It doesn’t consider the effect of time and

9. Travelling Salesman problem
It is a network problem consisting of finding a route
from one node to another that yield minimum
cost.
Objective Function:
n-1 n
minimize Z= ∑ ∑ Cij xij
i=1 j=1
TSP can be solved by the technique of Assignment
problem

11. CONCLUSION
By the help of assignment problem the TATA
Motors can maximize its profit and also minimize
their cost of production.
As it is a forecasting method some time it will not
give appropriate answer.
