Chapter 15, Problem 6P
A firm makes a basic scissors consisting of three parts: the left side, the right side, and the screw that holds the sides together. At the present time, the firm has the following numbers of parts on hand and on order. The lead times for reorder of each part are also shown along with a BOM and a sketch of the scissors.
| 0 | On Hand | Weeks of Lead Time | Scheduled Receipts |
| Scissors | 100 | 1 | |
| Left side | 50 | 2 | 100 in week 2 |
| Right side | 75 | 2 | 200 in week 2 |
| Screw | 300 | 1 | 200 in week 1 |
- a. Assume the master
schedule calls for 200 scissors to be shipped in week 4 and 500 in week 5: work out a complete materials plan. - b. Suppose the supplier of right-hand sides calls to say that deliveries of the 200 parts on order will be one week late. What effect will this have on the materials plan?
- c. If demand for scissors is uncertain and has a standard deviation of 50 units, what would you recommend the firm do to maintain a 95 percent service level for scissors?
- d. If the delivery of the scissors parts is unreliable and the standard deviation of delivery' lead time is one week for each of the parts, what would you recommend the firm do to maintain its production schedule?

A’s lead time is 1 week; B’s lead time is 2 weeks; and C’s lead time is 2 weeks. This is true regardless of order size. Currently you have the following amounts in on-hand inventory; A = 50. a) How many units of B and C will I need to produce for A if I have an order for 100 units of A? b) Give me a time-phased assembly plan for A, B, and C such that I will receive 100 units of A at the beginning of Week 5. Assume that I can work on B and C at the same time (overlap).

i was reading this answer and the way its calculated is a longer process then what someone else wrote can you check if ishould use this one that bartleby has given me or the other one:
Step 1: Basic Information
The question is related to Economic order quantiy Economic Order Quantity is that level of inventory at which ordering cost and handling cost are minimum. It is calculated with the help of following formula
Economic Order Quantity = √2RO ÷ C
R = Annual Requirment
C = Carrying or Holding cost
O = Ordering Cost
Step 2: Solution
Economic Order Quantity = √2RO ÷ C
Economic Order Quantity = √2 × 3000 × 20 ÷ 4.25
Economic Order Quantity = √28,235.294117647
Economic Order Quantity = 168.0336100834 pounds
R = Annual Requirment i.e.250 × 12 = 3000 pounds per annum.
C = Carrying or Holding cost i.e. £4.25
O = Ordering Cost i.e. £20
Quantity to be ordered = 168.03 pounds.
Supplier = Vendor 1 should be used as the cost per pound for 168 pounds is £32.25 (as per table…

- For Question 1 you are required to mannualy (without the use of excel) develop two MRP matrices: one with no lot sizing (you order what is required) and a lot seize equal to the EOQ. To determine the EOQ note that the inventory carrying cost is given as R1/unit/period. This means that you have to calculate the average demand per period and use this demand value in your EOQ calculation. This is then the order quantity to be used for the second MRP matrix.arrow_forwardComplete the master production schedule based on the following information On-hand Inventory - 160 schedule production whenever projected on-hand inventory drops below - 30 MPS lot size - 300 Week 1 2 3 4 5 6 7 8Forecast 120 100 130 110 140 140 170 180 Customer Orders 110 100 75 50 32 11 5 0Projected On-Hand Inventory 160MPSAvailable-to-Promisearrow_forwardState the types of data that would be carried in the bill-of-materials i le and the inventoryrecord file.arrow_forward
