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 condfidence
level of 80%.
2 M̲E̲T̲H̲O̲D̲O̲L̲O̲G̲Y̲
2.1 P̲E̲R̲I̲O̲D̲ ̲O̲F̲ ̲S̲U̲P̲P̲O̲R̲T̲
The PSPL has been prepared for a supply depot, which
supports three sites for a period of 270 days.
2.2 C̲O̲V̲E̲R̲A̲G̲E̲
The RSPL is based on the equipment matrix of the three
sites.
2.3 B̲A̲S̲I̲S̲ ̲F̲O̲R̲ ̲C̲A̲L̲C̲U̲L̲A̲T̲I̲O̲N̲
2.3.1 S̲i̲t̲e̲ ̲L̲e̲v̲e̲l̲
No site level spares are recommended
There is normally a redundant Protocol Converter equipped
at each site.
2.3.2 D̲e̲p̲o̲t̲ ̲L̲e̲v̲e̲l̲
2.3.2.1 C̲R̲8̲0̲ ̲M̲o̲d̲u̲l̲e̲ ̲S̲p̲a̲r̲e̲s̲
The depot level RSPL has been prepared to support the
sites for 270 days. The CR80 modules which are identical
with parts used in CAMPS equipment are marked with
an "a" in the RSPL in section 5.
2.3.2.2 P̲e̲r̲i̲p̲h̲e̲r̲a̲l̲ ̲S̲p̲a̲r̲e̲s̲
It is not considered necessary to recommend a VDU kit
to support the three VDUs at a depot, which besides
support about 250 VDUs.
2.3.3 I̲n̲s̲u̲r̲a̲n̲c̲e̲ ̲T̲y̲p̲e̲ ̲I̲t̲e̲m̲s̲
Insurance type items are items, which though not required
for pure statistical reasons, must be included for
operational reasons.
2.4 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 electronis 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 are given
by the Poisson distribution:
p (i) = (t/MTBF)…0e…i…0f… x exp(- t/MTBF)
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:
P (failures r) = …0e…r…0f… (t/MTBF) …0e…i…0f…x exp(-t/MTBF)
i = 0 i!
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
max m x exp (-m)
r i = r+1 i ! .20
r = number of spares required to obtain the
re
quired confidence level
m = N x T
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
.80 exp (-m) x m
i = 0 i!

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.
All prices in this RSPL are per 1st May, 1982.
Component prices are at cost and does not include handling
and mark up.
3.1.2 F̲o̲r̲w̲a̲r̲d̲ ̲P̲r̲i̲c̲i̲n̲g̲
The forward pricing factor to be applied to above unit
prices is 1% per month.

Prices are ex works (Ballerup)
3.2 V̲A̲L̲I̲D̲I̲T̲Y̲
This bid for supply of spare parts in accordance with
the RSPL is open for acceptance until 60 days after
the receipt of an acceptable RSPL.
3.3 D̲E̲L̲I̲V̲E̲R̲Y̲
After production testing, CR will put the spares in
storage. By this event SHAPE takes title to the spares.
3.4 T̲E̲S̲T̲I̲N̲G̲
Production testing of CR spares will be performed according
to CR's normal production test procedures.
