1) Solve
1 point
a transportation problem with three supply points and
three demand points. The supplies are 80, 60 and 70 while the
demands are 90, 75 and 45. The unit costs of transportation are 8, 5,
6, 4, 7, 9, 10, 12 and 11 respectively. What is the optimal
transportation cost?
Use VAM for initial solution and MODI method for optimality check.

2) Consider
a two stage transportation problem where there are 3 1 point
factories, 3 warehouses and 2 retailers. The supplies are 80, 60 and 70.
The warehouse capacities are 90, 75 and 45. The demands are 100
and 110 at the retailers. The unit costs of transportation between
factories and warehouses are 8, 5, 6, 4, 7, 9, 10, 12 and 11
respectively. The unit cost of transportation between warehouses and
retailers are 8, 12, 14, 10, 9 and 10. Solve a multistage transportation
problem.What is the optimal transportation cost for the entire two
stage problem?

3) Solve
a fixed charge transportation problem with three supply 1 point
points and three demand points. The supplies are 80, 60 and 70 while
the demands are 90, 75 and 45. The unit costs of transportation are 8,
5, 6, 4, 7, 9, 10, 12 and 11 respectively. The fixed costs are 300, 200,
400, 600, 700, 400, 800, 650 and 550 respectively. What is the
optimal transportation cost ?

4) Items
1 point
have to be distributed from a warehouse to eight
retailers. A full track load goes every time. The travel times are 90, 77,
65, 53, 45, 30, 25, 8. Each truck is available for 100 minutes. Use the
first fit decreasing heuristic to solve the problem. Find minimum
number of trucks required?

6) Solve the VRP with a depot and 5 cities. The distance between 1 point
the warehouse and the 5 locations are 12, 18, 16, 14 and 18. The
demand in 5 cities is 4, 6, 5, 7 and 8 the vehicle capacity is 20. Solve a
VRP? Use the distance matrix given below.
Find the largest savings based on Clarke and Wright heuristic,
The largest savings is for 4-5 with s45 = 23
The largest savings is for 2-4 with s24 = 30
The largest savings is for 3-5 with s35 = 28
The largest savings is for 3-5 with s35 = 26
No, the answer is incorrect.
Score: 0
Accepted Answers:
The largest savings is for 3-5 with s35 = 26
7) Solve the VRP with a depot and 5 cities. The distance between 1 point
