<p>A method for processing bill of material data in which low-level codes are updated in a bottom-to-top direction, from component items to subassemblies to assemblies. Updating the low-level code on a bottom to top traversal of a hierarchical path eliminates the need to maintain copies of the original low-level codes for recovery purposes. Continuity checking is performed before the low-level codes are updated. Low-level coding is extended for use in project network processing by substituting for the low-level code, the activity early start time in the forward pass and late finish time in the backward pass, and substituting for the increment value used in low-level coding, the activity duration time. <IMAGE></p> |
