BOM explosion is a standard problem for any manufacturing or assembly company.
Ford, GM, Daimler/Chrysler are the canonical examples of such organizations.
A dealer orders a 2005 Magnum XI, with some set of requested features.
The order goes in, and gets recursively exploded into successively more detailed sets of inventory requests.
You need a car; that means you need:
- Chassis
- Engine
- Drive train
- Wheel assemblies, and everything to connect them to the drive train
- Seats
The engine, then, is a subsystem that must itself be exploded into a further bill of materials representing the components needed to build the engine.
Stereo makers (Panasonic, Pioneer, Sony, Harmon Kardon, ...) will have somewhat simpler BOM explosions. You may buy a stereo "system" which consists of:
- Receiver/Amp
- DVD player
- Tape deck
- Speakers
- Cabling
