[[Lambda].sub.ijh] = the pegged quantity per assembly multiplied through all levels of end item i for component j.
The TCI varies with the changes in demand and quantity per assembly. Consider production system I, suppose all quantities per assembly ([[Delta].sub.KK][prime]) and end item demands ([Q.sub.i]) equal 1.
Quantity usage or quantity per assembly. This experiment focuses on purchased parts commonality, and only quantity usage between levels 1 and 2 of the product structure (such as [[Delta].sub.37]) are varied.
