- The table below provides demand data for 6 weeks (weeks 31-36 for the current year) for one product. Inventory is managed with a periodic review system where T = 5 weeks and M = 280. The previous order was for 120 units at the end of week 28. The lead time is a constant 4 weeks. At the beginning of week 31 the inventory level is 130 units. Orders are made at the end of a week. 1. When is the next order? end of week __________ 2. How large is the next order? ___________ Week Demand Inventory 31 30 32 40 33 45 34 30 35 30 36 30A company wants to develop a level production plan. The beginning inventory is zero. Demand for the next four periods is given in what follows. What production rate per period will give a zero inventory at the end of period 4? When and in what quantities will back orders occur? What level production rate per period will avoid back orders? What will be the ending inventory in period 4?

The lot-sizing rule is, again, fixed order period using two periods. Lead time is three periods. Determine the planned order release schedule for the gear. Suppose each gear assembly requires two pinions. Currently there are 100 pinions on hand, the lot-sizing rule is lot-for-lot, and the lead time is one period. Determine the gross requirement and then the planned order release schedule for pinions.Leather-All produces a line of handmade leather products. At the present time, the company is producing only belts, handbags, and attache cases. The predicted demand for these three types of items over a six-month planning horizon is as follows: Month No. of Belts Handbags Attache CasesWorking days1 22 2500 1250 2402 20 2800 680 3803 19 2000 1625 1104 24 3400 745 755 21 3000 835 1266 17 1600 375 45 The belts require an average of two hours to produce, the handbags three hours, and the attache cases six hours; all the workers have the skill to work on any item. Leather-All has 46 employees who each have a share in the firm and cannot be fired. There are an additional 30 locals that are available and can be hired for short periods at a higher cost. Regular employees earn $8.50 per hour on regular time, and $14.00 per hour on overtime. Regular time comprises a seven-hour workday and the regular employees will work as much overtime as is available. The additional workers are hired for…A single inventory item is ordered from an outside supplier. The anticipateddemand for this item over the next 12 months is 6, 12, 4, 8, 15, 25, 20, 5, 10, 20, 5,12. Current inventory of this item is 4, and ending inventory should be 8. Assume aholding cost of $1 per period and a setup cost of $40. Determine the order policyfor this item based ona. Silver–Meal.
- [item no. 11] In a single period inventory model, the demand is assumed to follow a normal distribution. The value of ML/(ML+MP) is 0.6. The company used marginal analysis with the normal distribution to determine the optimal stocking level X*. If the mean demand is 100, then X* a. is less than 100 b. is equal to 100 c. cannot be determined from the information given d. is greater than 100The ATV Corporation makes three models of all-terrain vehicles: Model A, Model B, and Model C. Model A uses a 0.4-liter engine, Model B uses a 0.5-liter engine, and Model C uses a 0.6-liter engine. The aggregate production plan is the twelve-month plan that combines all three models together in total monthly production. The planning horizon is twelve months. The APP determines the size of the workforce, which is the constrained resource. Assume that the beginning inventory for January is 120 units (30 units each of Model A and Model B, and 60 units of Model C). The firm desires to have an ending inventory of 160 units at the end of the year. On average, one unit of ATV requires eight labor hours to produce, and a worker contributes 160 hours (8 hours × 5 days × 4 weeks) per month. The data has been collected in the Microsoft Excel Online file attached. Answer the question below: 1. What are the totals of the forecast demand (including inventory adjustment for December), production,…The production planning period for flat-screen monitorsat Louisiana's Rao Electronics, Inc., is 4 months. Cost dataare as follows: CEO Mohan Rao expects to enter the planning period with 500monitors in stock. Backordering is not permitted (meaning, forexample, that monitors produced in the second month cannot beused to cover first month's demand). Develop a production planthat minimizes costs using the transportation method.

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.Please help me solve this table. Rockit Electronics manufactures a line of digital blue ray players. The player is made from one subassembly of B and one subassembly of C. B is made of three units of D and two of E. C is made of two units of F and two of E.The blue ray has a lead time of one week. B, C, and E have lead times of two weeks, and D and F have lead times of three weeks.As the production manager, you need to figure out the MRP planning schedule. 1. What is the bill of materials (product structure tree)?2. If 1,000 units of blue ray players are required in week 10, what is the MRP schedule? Specifically, when items are to be ordered and received. Assume we have no units of inventory on hand.
