Option F: Cancel. Here, OTA assumed that the Phase 11 OCR procurement would be cancelled, as would the ZIP+4 program and related rate incentives. The 252 single- line OCRs purchased in Phase I would be used to process 5-digit ZIP mail. OTA assumed
that maintenance and spare parts costs address directory information update
be the same, Clerk carrier
but that savings
there would be no for option F were
assumed to be the same savings achievable at 90
as with zero percent ZIP+4 use; that is, percent ZIP+4 use, per USPS estimates.
OTA used option F as the baseline against which incremental cash flows of other options can be measured.
For option G, OTA assumed that the 252
purchased now, installed in option D except at one-half
1985-87, and converted to the number of single-line
multi-line in 1988-90 (same as OCR units); and 201 multi-line
OCRs would be purchased after release-loan testing and installed in 1988-90 (same as option B except at one-half the number of multi-line OCR units).
Thus, option G is an intermediate option between options B and D and would be expected to roughly split the difference between the two.
Option H: option G except
90-10 for the
Split Procurement. Option H
is based of 202)
on the same assumptions as additional single-line OCRs
would be purchased now, installed in 1985-87, and converted 40 (instead of 201) multi-line OCRs would be purchased after installed in 1988-90.
