Why is accurate inventory such an important issue at Wheeled Coach?

Problem 21-16 (Algo) 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, 30, and 25 units of on-hand inventory. 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 90, respectively, to be purchased. B has scheduled receipts of 20 units in Period 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, 10 units in Period 2, 55 units in Period 6, and 50 units in Period 8.   Find the planned order releases for all items. (Leave no cells blank - be certain to enter "0" wherever required.)

Item X is a standard item stocked in a company's inventory of spare parts. Each year, the firm uses about 2,000 units of Item X, which costs Php 1,000 per unit. Storage costs, which include insurance and cost of capital, amount to 18 percent of item unit cost. Placing an order for more of Item X costs Php 400. The company operates 360 days per year and Item X is received 9 days after placement of order.

One unit of A is made of one unit of B and one unit of C. B is made of four units of C and one unit each of E and F. C is made of two units of D and one unit of E. E is made of three units of F. Item C has a lead time of one week; Items A, B, E, and F have two-week lead times; and Item D has a lead time of three weeks. Lot-for-lot (L4L) lot sizing is used for Items A, D, and E; lots of size 50, 100, and 50 are used for Items B, C, and F, respectively. Items A, C, D, and E have on-hand (beginning) inventories of 15, 55, 100, and 10, respectively; all other items have zero beginning inventory. We are scheduled to receive 10 units of A in Week 1, 100 units of C in Week 1, and 100 units of D in Week 3; there are no other scheduled receipts.If 50 units of A are required in week 10, use the low-level-coded bill-of-materials (product structure tree) to find the necessary planned-order releases for all components. (Leave the cells blank, whenever zero (0) is required.)
