3) Either Holding or Ordering cost is minimum
Which amongst the following is true for EOQ?

Question 3

For the data given below:

Use the Jackson’s Extension to calculate the total processing time.

Question 4

The average number of customer in the system(L_s) and average number of the customer in the queue (L_q) is related as

Question 5

Vehicle manufacturing assembly line is an example of_____.

Question 6

For inventory control model III, the ordering quantity was 500 units when the relation between Inventory cost (I) and Penalty cost (P) was given by:
P = I/2
With optimization, later this relation was reduced to:
P = I/4
What will be the optimised ordering quantity after the change?

Question 7

Market demand for springs is 8,00,000 per annum. A company purchases these springs in lots and sells them. The cost of making a purchase order is Rs. 1,000. The cost of storage of springs is Rs. 100
per stored piece per annum. The economic order quantity is:

Question 8

Two models, P and Q, of a product earn profits of Rs. 100 and Rs. 80 per piece, respectively. Production times for P and Q are 5 hours and 3 hours, respectively, while the total production time available is 150 hours. For a total batch size of 40, to maximize profit, the number of units of P to be produced is ____________.

Question 9

A project consists of 14 activities, A to N. The duration of these activities (in days) are shown in brackets on the network diagram. The latest finish time (in days) for node 10 is __________.

Question 11

At a work station, 5 jobs arrive every minute. The mean time spent on each job in the work station is 1/8 minute. The mean steady state number of jobs in the system is ______

Question 12

Fifty observations of a production operation revealed a mean cycle time of 10 min. the worker was evaluated to be performing at 90% efficiency. Assuming the allowances to be 10% of the normal time, the standard time (in seconds) for the job is_______.

Question 13

Service workshop has four jobs on hand to be processed. The date and processing time for each of the jobs are given below:

Using the shortest processing time (SPT) rule, total tardiness is

Question 14

Profit matrix is given which give profit obtained per unit for transportation from factories to market. now using VAM method for given unit profit matrix find total loss in transportation.

Question 15

Two machines of the same production rate are available for use. On machine 1, the fixed cost is Rs.100 and the variable cost is Rs.2 per piece produced. The corresponding numbers for the machine 2 are Rs.200 and Re.1 respectively. The sale price of the first 800 units is Rs.3.50 per unit and subsequently, it is only Rs.3.00. The breakeven production rate for each machine is
