In one embodiment, a method for repair planning for a location in a repair
network includes modeling: (1) an uninspected buffer for parts received
but not yet inspected at the location; (2) a first buffer for parts
inspected at the location and repairable at the location; (3) a second
buffer for parts inspected at the location and not repairable at the
location; (4) a third buffer for parts inspected at the location and not
repairable at any location in the repair network; and (5) a fourth buffer
for parts inspected at the location and serviceable without repair. The
parts in the uninspected buffer are assigned to the first, second, third,
and fourth buffers at corresponding rates according to an inspection
operation. One or more operation plans are generated to push parts out of
the uninspected buffer to the first, second, third, and fourth buffers
according to the corresponding rates, a part pushed out being available
within the first, second, third, or fourth buffer only after a
predetermined disposition time has elapsed. An operation plan is
generated to push parts out of the second buffer to one or more upstream
locations, a part pushed out being available at an upstream location only
after a predetermined move lead time has elapsed. For each part pushed
out of the uninspected buffer to the first or second buffer, the earliest
time at which repair can begin for the part is estimated, this earliest
repair time determining the earliest time at which, after the part has
been repaired to make it serviceable, the part can be available to
satisfy a demand at the location.
