(i) Production control charts
(ii) JIT

Q.4 (i) Discuss in brief the various tools of method analysis.   [7]

Q.5 What do you mean by inventory control ? Discuss the various tools of inventory management ?   [14]

Q.6 What do you understand by network analysis ? Explain its objective.   [14]

SECTION-B

Q.7 Case study/problem :   [14]
A dealer supplies you the following information with regard to a product dealt in by him :
Annual demand = 10,000 units
Ordering cost = Rs 10 per order
Inventory carrying cost = 20 per cent of the value of inventory per year.

The dealer is considering the possibility of allowing some backorder(stockout) to occur. He has estimated that the annual cost of backordering will be 25% of the value of inventory.

(a) What should be the optimum number of units of the product he should buy in one lot ?

(b) What quantity of the product should be allowed to be backordered, if any ?

(c) What would be the maximum quantity of inventory at any time of the year ?

(d) Would you recommend to allow backordering ? if so, what would be the annual cost saving by adopting the policy of backordering ?

The Questions paper is divided into two sections.Sections A contains 6 questions out of which the candidate is required to attemp any 4 questions. Section B contains short case study/application based on 1 question which is compulsory.

                                         All questions are compulsory.

SECTION-A

Q.1(a) What is mean by the term operations ? How does it differ from the term production ?[4]
(b) List the factors with reasons to be considered for the establishment of petroleum refinery at BARMER.[4]
(c) Develop a trend line for the following data to forecast the demand for the period 10 and 11 : [6]

Period	Demand
1	44
2	52
3	50
4	54
5	55
6	55
7	60
8	56
9	62

Q.2(a) Using data, obtain the EOQ and the total variable cost associated with the policy of EOQ.
Annual demand = Rs. 20,000
Ordering cost = Rs. 150 per order
Monthly Inventory carrying cost = 2 % of average inventory value.          [8]

(b) Review the assumption of EOQ model used in the derivation.            [3]

(c) Describe the philosophy of JIT with respect to inventory.                  [3]

Q.3 (a) A company plans to assign 5 salesman to 5 districts in which it operates. Estimates of sales revenue in thousands of rupee for each salesman in different districts are given in the table shown. What should be the placement of the salesman if the objectives is to maximise the expected sales revenue ? [7]

District Salesman	D1	D2	D3	D4	D5
S1	40	46	48	36	48
S2	48	32	36	29	44
S3	49	35	41	38	45
S4	30	46	49	44	44
S5	37	41	48	43	47

(b) Solve the following transportation problem. Obtain the initial solution by NW corner rule.

To From	P	Q	R	S	Supply
A	7	3	8	6	60
B	4	2	5	10	100
C	2	6	5	1	40
Demand	20	50	50	80	200

Obtain the optimal solution.     [7]

Q.4(a) A company manufactures 30 units per day. The sales of these items depends upon demand which has the following distribution :

Sales(units)	Probability
27	0.10
28	0.15
29	0.20
30	0.35
31	0.15
32	0.05

The production cost and sales price of each unit are Rs.40 and Rs.50 respectively. Any unsold product is to be disposed off at a loss of Rs. 15 per unit. There is a penalty of Rs. 5 per unit if demand is not met. Using the following random numbers, estimate the total profit/loss for the next ten days :
10,99,65,99,95,01,79,11,16,20
