3. Consider the three item disaggregation problem with D1 = 300, D2 = 400, D3 = 200 and P= 1500. Assume I1 = 150, I2 = 300 and I3 = 80. Assume t1, t2, t3 be the start times of production of items.

A. The maximum value of t1, t2, t3 should be respectively

Answer: (0.5, 0.75, 0.4)

B. The order of the procedure is

Answer: (3-1-2)

C. If t1=0.03, t2=0.1, t3=0.15, what is the inventory of item 1 at t1 *_*

Answer: 141

4. In Disaggregation problem, the inventory is taken in

Answer: Number of manhours

5. Will the part period balancing and Silver Meal heuristic always give the same solution?Yes

Answer: No

6. What is the objective function in a disaggregation problem?

Answer: Maximize the cycle time

7. The main objective in economic lot scheduling is

Answer: Minimize total cost

8. **_** is the amount of inventory on hand at which an order is placed

Answer: Reorder Level

sir please provide solution for fundamentals of manufacturing process NPTEL course. Because this course is very important for my present academics. Eagerly waiting for your replay thanking you with regards

Question 3 , part-3..i think the answer is different because they have asked for item 1 .The answer 119 is the inventory level of item 3 according to the rearrangement made in the order of manufacturing.

i m getting the same doubt , my answer is 141

Can you provide the correct answer?
