3. What is the importance of integer programming models in supporting managerial
decisions? Describe the rationale behind Cutting Plane Method used for solving integer
programming models.
4. A wholesaler supplies 30 stuffed dolls each day to various shops. Dolls are purchased
from the manufacturer in lots of 120 each at Rs. 1200 per lot. Every order incurs a
handling charge of Rs 60 plus a freight charge of Rs 250 per lot. Multiple and fractional
lots can also be ordered, and all orders are met the next day. The incremental cost is Rs
0.60 per year to store a doll in inventory. The wholesaler finances inventory investments
by paying its holding company 2% monthly for borrowed funds.
How many dolls should be ordered at a time in order to minimize the total annual
inventory cost? Assume that there are 250 week-days in a year. How frequently should he
order?
5. What is simulation? Describe the simulation process. State the major two reasons for
using simulation to solve a problem. What are the advantages and limitations of
simulation?
