1 S̲C̲O̲P̲E̲
The scope of this document is to present a Recommended
Spare Parts List (RSPL), which will support the achievement
of predicted availability of each site with a confidence
level of 80%.
2 M̲E̲T̲H̲O̲D̲O̲L̲O̲G̲Y̲
2.1 P̲E̲R̲I̲O̲D̲ ̲O̲F̲ ̲S̲U̲P̲P̲O̲R̲T̲
The RSPL for each site has been prepared to ensure
90 days of operation whereas the RSPL for the supply
depots has been prepared to ensure the presence of
spares required to supply the sites for a period of
270 days.
2.2 I̲N̲S̲U̲R̲A̲N̲C̲E̲ ̲T̲Y̲P̲E̲ ̲I̲T̲E̲M̲S̲
Insurance type items are items, which, though not required
for pure statistical reasons, must be included for
operational reasons or due to long lead time. Insurance
items have been included at site as well as depot level.
2.3 C̲O̲V̲E̲R̲A̲G̲E̲
a) At site level the RSPL is based on the equipment
matrix for main CAMPS equipment plus the main site
equipment matrix for CAMPS Remote Terminal (CRT).
The confidence further obtained by the introduction
of insurance items yields support for the CRT remote
sites and the remote TARE. This is in accordance
with the maintenance philosophy for remote sites
where peripherals are replaced as units and supported
from the main site.
b) The depot level RSPL is separated into a Northern
Depot RSPL supporting 10 sites, and a Southern
Depot RSPL supporting 6 sites. Items which are
kept as insurance supporting all 16 sites are allocated
to the northern depot in this RSPL.
2.4 B̲A̲S̲I̲S̲ ̲F̲O̲R̲ ̲C̲A̲L̲C̲U̲L̲A̲T̲I̲O̲N̲
a) Where no spares are recommended at site level,
the basis for the calculation of spares at the
depots has been the installed population.
b) If spares are recommended at site level, the calculation
of spares at the depots has been the site spare
population.
c) Where insurance items have been incorporated at
the site level, due considerations have been given
when calculating spares at the depot(s). All items
which have been given insurance considerations
are identified in the Remarks coloumn of the printout.
2.5 F̲O̲R̲M̲U̲L̲A̲ ̲F̲O̲R̲ ̲S̲P̲A̲R̲E̲S̲ ̲C̲A̲L̲C̲U̲L̲A̲T̲I̲O̲N̲
M̲e̲t̲h̲o̲d̲ ̲t̲o̲ ̲C̲a̲l̲c̲u̲l̲a̲t̲e̲ ̲N̲u̲m̲b̲e̲r̲ ̲o̲f̲ ̲S̲p̲a̲r̲e̲s̲
In order to determine the number of spares it will
be assumed that the failure rate of each module (circuit
board) has an exponential distribution. This approximation
holds true for electronic equipment throughout its
useful life, i.e. wear-out phenomena can be ignored.
Thus the probability mass function for each module
is:
p(t) = (1/MTBF) x exp(-t/MTBF)
where MTBF is the Mean Time Between Failure for that
module.
It can be shown that the probability of observing exactly
i failures over a period of t operating hours is given
by the Poisson distribution:
i
p (i) = (̲t̲/̲M̲T̲B̲F̲)̲ ̲ ̲ ̲x̲ ̲e̲x̲p̲(̲-̲ ̲t̲/̲M̲T̲B̲F̲)̲
i!
The Period t corresponds to the accumulated operating
period for the involved modules.
Therefore, the probability of observing r or less failures
during a period t is determined by the cumulative Poisson
distribution:
r i
(̲t̲/̲M̲T̲B̲F̲)̲ ̲ ̲x̲ ̲e̲x̲p̲(̲-̲t̲/̲M̲T̲B̲F̲)̲
P (failures r) =
i!
i = 0
To determine the number of spares r required to obtain
an 80% confidence level for a period of 90 days is
equivalent to determining the minimal r for which the
probability of having more than r failures during the
period covered is less than 20%.
The following equation has to be solved for r:
i =
i
m̲ ̲ ̲ ̲x̲ ̲e̲x̲p̲ ̲(̲-̲m̲)̲
max
i ! .20
r i = r+1
r = number of spares required to obtain
the
required confidence level
m = N x ̲T̲ ̲
MTBF
N = total installed parts population. The
total installed population for a depot is determined
by the number installed items at the sites
involved.
T = length of period for which stock is
required
i.e 90 days for sites and 270 days
for the
central depot(s).
MTBF = Mean Time Between Failure (MTBF = 10…0e…6…0f…/
)
= failure rate per million hours.
Alternatively determine smallest integer r for which
r i
m
.80 exp (-m) x ̲ ̲ ̲

i = 0

3.1 P̲R̲I̲C̲I̲N̲G̲
3.1.1 P̲r̲i̲c̲e̲ ̲B̲a̲s̲i̲s̲
The applicable CR unit prices for this bid are current
Customer List Prices as given in CR's standard customer
price list for CR80 Mini (81/07 CLP).
Piece parts (components) for CR equipment is estimated
to 30% of subassy value.
Piece parts (components) for OEM equipment is estimated
for each peripheral.
Component prices are at cost and does not include handling
and mark up.
Consumables such as paper, floppy discs, etc for OEM
equipment are not included.
15% of total quotation represents costs in US$. Therefore,
15% is payable in US$ applying an exhange rate of 100
US$ = Dkr. 750.
3.1.2 F̲o̲r̲w̲a̲r̲d̲ ̲P̲r̲i̲c̲i̲n̲g̲
The forward pricing factor to be applied to above unit
prices is 1% per month. Above unit prices have thus
been increased by 26.97% in order to reflect an average
escalation period of 30 months, i.e. from 1981-10-01
until 1983-10-01.
3.1.3 T̲e̲r̲m̲s̲ ̲o̲f̲ ̲D̲e̲l̲i̲v̲e̲r̲y̲
Prices are ex works (Ballerup)…86…1 …02… …02… …02… …02…
3.2 V̲A̲L̲I̲D̲I̲T̲Y̲
This bid for supply of spare parts in accordance with
the RSPL is open for acceptance until 1981-12-31.
3.3 D̲E̲L̲I̲V̲E̲R̲Y̲
After production testing CR will put the spares in
storage. By this event SHAPE takes title to the spares.
Delivery to sites will occur prior to SPA of the site
in question.
3.4 T̲E̲S̲T̲I̲N̲G̲
Production testing of CR spares will be performed according
to CR's normal production test procedures.
3.5 P̲E̲R̲I̲P̲H̲E̲R̲A̲L̲ ̲E̲Q̲U̲I̲P̲M̲E̲N̲T̲ ̲S̲P̲A̲R̲E̲S̲
At site level the peripheral spares consist of a kit
containing a set of replaceable modules. The kits are
derived from the peripheral manufacturer's RSPL.
Spares at the depot level consist of site level replenishment
kits, additional spares, plus piece parts for repair.
Selection of site level as well as depot level spares
has been performed in accordance with good engineering
practice concordant with the philosophy reflected in
the Maintenance Plan for corrective maintenance and
the selection of tools and test equipment. The following
peripherals are incorporated: …86…1 …02… …02… …02… …02…
a) VDU
One kit will support up to 12 VDUs. However, each
site is equipped with one kit only.
b) MSP
One kit will support up to 8 MSPs.
c) Disk, SMD, and MMD
One kit of each type till support 1-5 disks in
heavy use.
d) Floppy Disk
As a floppy disk station consists of 2 dualized
floppy disks powered from a common supply a floppy
disk unit will be returned to depot in case of
failure. Consequently, only the power supply will
be spared at site level.
At depot level, spares are composed of power supply,
floppy disks, and piece parts.
e) Frequency Stabilizer.
f) PTP/R
g) Stat. Mux.
The Stat. Mux. will be exchanged on a unit basis
at site. Consequently, no spares are incorporated
at site.
h) TARE Modem
No spare parts are contemplated at site level.
Modems will be exchanged as an entity. Consequently,
one spare modem is recommended at each site with
a TARE connection. Procurement of spare modems
is, however, not considered part of this RSPL.
As the type of modems is not yet decided spares
at depot level - both units and piece parts - is
selected as a multiplum of an estimated unit price.
i) Rack
A rack kit of isolating contact strips for 15 doors
has been selected at depot level. No racks, side
plates, doors, etc have been contemplated.
j) Misc
3.6 R̲E̲M̲O̲T̲E̲ ̲E̲Q̲U̲I̲P̲M̲E̲N̲T̲
The Remote Terminals equipment installed at the CAMPS
main site is included in the baseline for calculating
spares. Thus, the installed quantity column includes
both main CAMPS and CRT, main site equipment.
The CRT equipment installed at the remote sites and
Remote TARE equipment is not incorporated in the RSPL.
Peripherals are generally exchanged on a unit basis.
Spare modules provided at the main site will be used
for the remote installations.
