(4)

UNIT-ill

a) Explain the basic functions involved in the Inventory.    (4)

b) What is the function of n buffer Stock?

c) What is Lead Time? What are the factors will take into consideration while computing the Lead Time.    (4)

a) Compute the EOQ for the following:

No of units bought at time Price per unit Rs. Less than 1000 10.00 1000 to 2999 9.85 3000 to more 9.70

The order cost is Rs.60/- per order and carrying cost is 20% of the price. Annual requirement of the item is 10,000 units.    (12)

a)    Explain the MRP,    (4)

b)    Write short notes on Master production Schedule.    (4)

c)    What are the uses of ABC?    (4)

Product X is made of two units of y and three of z-y is made of one unit of A and two unit of B,Z is made of two units of A and four units of C.

Lead time for x is one week; y, two weeks; z, three weeks. A; two weeks; B, one week; and C three weeks, ff 100 units of x are needed in week 10, Develop a planning schedule shaving when each item should be ordered and in what quantity.

Also Draw the bill materials.    (12)

UNIT-V

a)    Discuss the use of the Gantt chart for scheduling purposes.    (4)

b)    Differentiate between loading and scheduling proposes.    (4)

c)    Explain the Jacksons rule.    (4)

-410. Consider the following Flow Shop Scheduling ptoblem:

Processing time
Job	M/C-l	M/C2	M/C3
1	3	4	10
2	11	1	6
3	8	10	14
4	10	12	2
5	6	4	2

Check Whether Johnsons rule can be applied? If not, solve the problems using Palmars heuristic.    (12)
