1 S̲C̲O̲P̲E̲
This document describes the baseline of the CAMPS SPARE
PART DATA BASE (CSPDB) which shall handle the spare
part list for CAMPS
Three types of spare list will be geerated for CAMPS:
1. SITE (1-16) (16 lists)
2. SUPPLY DEPOTS (1-2) (one list)
3. REPAIR DEPOTS (1-2) (one list)
The system IMS at Chr.Rovsing at Marielundsvej will
be used.
2 D̲A̲T̲A̲ ̲B̲A̲E̲ ̲S̲I̲Z̲E̲
Each item requires allocated storage for:
11 alphanumeric fields of 17 bytes
10 numeric fields of 15 digits
1 alphanumeric field of 80 bytes
There will be approximately 6000 items with up to 100
different entity names and fieldheadings.
5 megabytes are an adequate size for the data base.
10000 items with 500 bytes each.
3 T̲E̲R̲M̲I̲N̲A̲L̲-̲D̲I̲S̲P̲L̲A̲Y̲
The displayed picture is constructed in such a way
that all stored information for one item can be displayed
with entity name and field headings on one pag of the
screen.
The terminal must be on-line without restrictions from
0800 to 1730 hours.

5.1 G̲e̲n̲e̲r̲a̲l̲
Each page of the printout shall start with a headline
text followed by all the headings of the column…0e…s which
may take up two lines.
The name of he next higher level of the following items
shall be printed on the first line of the matrix.
Each item shall only take up one line.
If a new next higher level is to be printed on the
same page, an empty line followed by the new level
name shal be printed.
The printing facility shall not be less than 131 characters
per line.
Examples of the different printout's are shown on fig.5.2-1,
fig. 5.3-1, fig 5.3-2 and fig.5.3-3.
5.2 E̲Q̲U̲I̲P̲M̲E̲N̲T̲ ̲M̲A̲T̲R̲I̲X̲
CAMPS has SIX equipment delivered matixes:
MAIN SITE EQUIPMENT
CRT MAIN SITE EQUIPMENT
CRT REMOTE EQUIPMENT
TARE MAIN EQUIPMENT
TARE REMOTE EQUIPMENT
CAMPS SYSTEM EQUIPMENT
The first column headings of these matrixes are:
LINE NO
ITEM DESCRIPTION
The following coumn headings are the names given in
4.1.
An example of the equipment matrix is shown on fig.5.2-1.
CAMPS SYSTEM EQUIPMENT MATRIX is the matrix sum of
the five other matrixes.
The information for the different matrixes are obtained
from all the files for the units with relevantschemes
relating to the different sites.
5.3 S̲P̲A̲R̲E̲ ̲M̲A̲T̲R̲I̲X̲ ̲ ̲(̲S̲P̲L̲)̲
The headline text is:
SITE XX or
SUPPLY DEPOT or
REPAIR DEPOT
The column headings and width of the column's for four
matrixes with different column sequncies are listed
on page 13. The printout can be selected between these
four matrixes, this choice is made as the printer is
limited to 132 characters per line.
The first column, LINE NO is not a consecutive sequence
but is used both as an identifer and as a hierarchy
for all print out listings. Line numbers from 0001
to 0999 are used for subassembly and linenumbers from
1000 to 9999 are used for piece parts.

The information to the following column's ITEM NAME,
DESCRIPTION, NATO CODE, USER CODE, USER P/N, MFG CODE,
TRUE MFG P/N and MTBF/1000 are taken from the relevant
item files.
Th column QTY SYS is calculated by summing the quantity
used on the next higher level times the number of this
level in the system.
The columns RECSPA is the quantity recommended as spares,
this quantity is calculated as shown in 5.3.
The column CTSPA is the quantity of the actual delivered
spares. This number is obtained by either insure or
force the calculated quantity and it is a manual choice.
As close to the ratio 6 to 10 as possible but with
the quantities still as integers the actal spares are
divided between the two depots. The program checks
that the following statement is true:
(QTY.spares) = (QTY. AFCENT) + (QTY.AFSOUT)
If the statement is not true, due to manual change,
the (QTY AFSOUTH) is automaticly corrected.
The column ITEM PRICE is obtained from item files. As this price is in
DOLLARS the price is multiplied with the exchange price before the printout.
The column TOTAL PRICE is a result of the column ITEM
PRICE multiplied with the actual quantity.
A grand total is summed of the column TOTAL PRICE and is written below
the matrix.
Examples of the SPL are shown on fig. 5.3-1, 5.3-2
and 5.3-3.
5.4 S̲P̲L̲ ̲C̲A̲L̲C̲U̲L̲A̲T̲I̲O̲N̲
The data program for SPL shall be made not only to
handle the CAMPS project but also be so flexible that
it can handle future requirements.
The foundations or SPL are the equipment matrixes mentioned
in 5.2.
All the information for these matrixes is in the data
files.
LOWER For future requirements there shall be
PRITORITY facility to enter and store several of
these matrixes of made up examples.There
shall be facility for a variable number
of sites, supply depots and repair depots.
The different matrixes shall on request be printed
partly or fully. Further it shall be possible to add
two, three or more of the matrixes and to store the
rsult.
From each quantity of equipment and for each site or
depot the number of spares are calculated as "r".
"r" = the smallest integer for which:
confidence ̲ exp (-m) *
when: 0 ̲ confidence ̲ 1
m = N * …0e… ̲T̲ ̲ ̲…0f…
…0e…MTBF
N = Total quantity of installed equipment
T = length of period for which stock is required
in days.
MTBF = meantime between failures (is obtained
from the data file) in hours.
"T", "N" and the chosen "CONFIDENCE" are variables
which will be entered separately and be printed below
the matris.
It shall be possible to either force (reduce) or insure
(incease) the recommended quantity of spares and the
result will be presented as the actual spares in the
column ACT SPA.
When the actual spares have been decided the actual
CONFIDENCE for each item is calculated and printed
in the column P%.
The mtrixes shall then be stored for later retrieval.
The DATA BASE shall be able to store a small number
of these SPL's.
A grand total in Dollars is calculated as the sum of
the column TOTAL PRICE and is printed below the matrix.
An alternative mthod to calculate the quantity
of spares is as following and shall be available:
If for instance 10% of the grand total price
for the installed equipment is used to buy
LOWER PRIORITY spares, then all the recommended spares are
first set equl zero and the P is calculated.
The spare quantity for the item with the lowest
P is incremented by one and the unit price
for that item is deducted the price to buy
spares for, than the new P is calculated and
the process is repeated until the avalable
price to buy spares for is below zero.
6 D̲A̲T̲A̲ ̲S̲E̲G̲M̲E̲N̲T̲
Each item has a data segment where all the available
information can be entered in the relevant fields.
The entity picture form of these data files is shown
in Fg. 6-1.
To each data file belongs a relation scheme. This scheme
is entered with information of the quantity of this
item used on the next higher level.
The program shall check for repetition each time a
new item is about to be entered, and if heitem has
been created in the file previously only the relation
scheme will be updated.
