Question
Chapter 8.1, Problem 7P
Summary Introduction
Interpretation:Compare the lot-for-lot
Concept Introduction:Lot-for-lot scheduling is one of the dynamic lot sizing techniques utilized in MRP for determining optimum order quantity which should be the same as the required quantity.This is utilized when it is required to determine lot quantities in each period and also maintaining a safety stock.
Other comparable techniques are also available.

What alternatives are there to lot-for-lot scheduling at each level? Discuss thepotential advantages and disadvantages of other lot-sizing techniques
Assume that you are the manager of Assembly, Inc. You have just received an order for 40 units ofan industrial robot, which is to be delivered at the start of week 7 of your schedule. Using the following information, determine how many units of subassembly G to order and the timing of thoseorders, given that subassembly G must be ordered in multiples of 80 units and all other componentsare ordered lot-for-lot. Assume that the components are used only for this particular robot.Item Lead Time (weeks) On Hand ComponentsRobot 2 10 B, G, C(3)B 1 5 E, FC 1 20 G(2), HE 2 4 —F 3 8 —G 2 15 —H 1 10 —

- Can the optimal stocking level in the single-period model ever be less than expected demand?Explain briefly.arrow_forwardAmong the 4 major layers of stack token, namely, liquidity provider, validator system, token standard, and Blockchain, which of them is most of important and less important. Explain briefly.arrow_forwardProblem 6 Part A:Available to promise in period 4 = 50Problem 6 Part B:PAB in period 7 = 35 In part A, the only thing that you need to do is to calculate the ATP in periods 1,4,5, and 7. In part B, remember that you are rolling through time. The part B solution spreadsheet starts with time period 2 and period 1 is now history. For the part B, you must capture all of the events that occurred during week 1. For example, I gave you that the beginning PAB is 45. If you had 20 in stock (from part A), you produced 50 as planned in period 1, and the actual demand for period 1 was 25, then the beginning PAB (your stock quantity) is 20+50-25=45. The forecast and MPS quantities will not change from part A to part B. After you accept each of the orders (simply add the new order quantities to the existing customer order quantities in the correct time bucket), you will then recalculate the PAB, and then recalculate the ATP.arrow_forward
- Irvine Consolidated Closets (ICC) builds and sells shelving for homes and offices. For a certain shelving unit, SS1, ICC has gross requirements of 500, 800, and 650 units in weeks 4, 5, and 6, respectively. The lead-time on the SS1 shelving unit is two weeks. ICC currently has 600 of the SS1 on hand and this product is ordered in lot sizes of 300, that is, the order in multiples of 300. Determine the MRP schedule for the SS1 unit over a time frame of weeks 1 through 6. When and for how many units should ICC place their orders for the SS1? A key component of the SS1 is the TT2. Each SS1 contains four TT2s. Currently TT2’s are ordered in lots of size 1000 and there are 800 on hand. TT2s have a one-week lead time. Determine the MRP schedule for the TT2 unit over a time frame of weeks 1 through 6. When and for how many units should ICC place their orders for the TT2? Suppose annual demand for the SS1 shelving unit is 32,500. ICC’s holding cost is $0.50 per week for each SS1…arrow_forwardThe objectives of scheduling include all of the following except: A. Increased inventories in order to maximize profits. B. The ability to balance conflicting goals. C. Effective use of facilities, labor, and equipment. D.

- Valles Galactic Industries (VGI) owns a small company (VGI-Durango Sur) that manufactures various electronic products for original equipment manufacturers.   Customer companies provide engineering designs, materials lists, and some unique materials. VGI-DS provides labor and space for the manufacturing and assembly operations and stocking a variety of inventory items for production, such as wire, cables, some electronic components, etc. Thus, VGI-DS orders a variety of components and raw materials by contract. The labor pool is primarily composed of about 100 retirees picking up extra cash by working four to six-hour shifts. Thus, the assembly operations must be simple and easy to teach.  Skilled employees must do several raw material conversions for packaging—there are currently three such employees. VGI-DS receives forecasts from VGI headquarters for planned production for two years on a rolling quarterly basis. Staff at VGI-DS develop schedules and inventory plans based on this…arrow_forwardYou know when you have arrived at the optimal solution in using the time-cost CPM scheduling model analysis when what happens?arrow_forwardEach unit of A is composed of one unit of B, two units of C, and one unit of D. C is composed of two units of D and three units of E. Items A, C, D, and E have on-hand inventories of 20, 10, 20, and 10 units, respectively. Item B has a scheduled receipt of 10 units in Period 1, and C has a scheduled receipt of 50 units in Period 1. Lot-for-lot (L4L) lot sizing is used for Items A and B. Item C requires a minimum lot size of 50 units. D and E are required to be purchased in multiples of 100 and 50, respectively. Lead times are one period for Items A, B, and C, and two periods for Items D and E. The gross requirements for A are 30 in Period 2, 30 in Period 5, and 40 in Period 8.

- One unit of A is composed of two units of B and three units of C. Each B is composed of one unit of F. C is made of one unit of D, one unit of E, and two units of F. Items A, B, C, and D have 20, 50, 60, and 25 units of on-hand inventory, respectively. Items A, B, and C use lot-for-lot (L4L) as their lot-sizing technique, while D, E, and F require multiples of 50, 100, and 100, respectively, to be purchased. B has scheduled receipts of 30 units inperiod 1. No other scheduled receipts exist. Lead times are one period for items A, B, and D, and two periods for items C, E, and F. Gross requirements for A are 20 units in period 1, 20 units in period 2, 60 units in period 6, and 50 units in period 8.
