To make an engine you require 2 pistons. Given the MPS for engines that you just calculated, determine the gross requirements for pistons, and determine if, when and how many you need to buy from your piston supplier to have enough on hand to produce to your master production schedule.

piston (Level 1)	Week 1	Week 2	Week 3	Week 4	Week 5	Week 6
Gross Requirements	1500	1000	2000	1500	0	0
Projected on-hand inventory (BI =2500)	1000	0	0	500	0	0
Net requirements	0	0	2000	1500	0	0
Planned order releases	0	2000	2000	0	0	0
Q = 2000, LT = 1, SS=0

If you use the same piston in a new engine that has a production schedule of 100 per week and this new engine requires 4 pistons per engine, then total gross requirements for the piston will be what you determined above plus ____ each week (dont factor this into your original calculations).

1. 400
2. 100
3. 200
