- Component Quantity Needed: At each level, the quantity required for each component is 1.
- Levels and On-Hand Quantities:
- Level 1 (Top Level):
- Bicycle is the end assembly.
- Minimum on-hand quantity at Level 1 is 8 (based on the lowest on-hand quantity, which is Front Parts Assembly).
- Level 2:
- Frame Parts: 20 on-hand.
- Gear Unit: 15 on-hand.
- Front Parts Assembly: 8 on-hand.
- The minimum on-hand quantity at Level 2 is 15 (based on the Gear Unit).
Because Front Parts Assembly ATB Calculation:
ATB value of Front Parts Assembly is increased by 18 due to the additional on-hand quantity of Headset (Level 3 component). i.e. 8 + ATB of Front Parts = 10 => Total is 18.
- Hence, ATB value at Top Level = 8 (L1)
- ATB value at All Levels = 15 (ATB at All Levels = 15″ means that the calculation considers the available quantities from Level 1 through all sub-levels (Level 2 and Level 3). It is not a direct sum but instead identifies how much can be assembled after analyzing all levels for constraints)
