Q. 1. Initially, assume which Phil wants to minimize his inventory requirements. Assume which each order will be only for illustrate what is required for a single period. Using the following forms, calculate the net requirements and planned order release for the gear boxes and input shafts. Assume which lot sizing is done using lot-for-lot.

2. Phil would like to consider the costs which his accountants are currently using for inventory carrying and setup for the gear boxes and input shafts. These costs are as follows:
Gear box Setup = $90/order
Inventory carrying cost = $2/unit/week
Input Shaft Setup = $45/order
Inventory carrying cost = $1/unit/week

Given the cost structure, Calculate the cost of the schedule from (1). Assume inventory is valued at the end of each week.

3. Calculate a schedule using least-total-cost lot sizing. Illustrate what are the savings with this new schedule?
