SOFTWARE PRODUCT (SP) RUSLAN
SP RUSLAN was designed at term from 1995 to
1999 as final release of a number of application packages for
support of process of technical exploitation of aircraft in the
airlines of former USSR, Cuba and Poland.
First of this series (for 1968 - 1978) were the
batch systems SP TOS, SP TOS-R. They are used more
than in 20 largest airlines, including airports
"Domodedovo","Pulkovo", airports of cities
Rostov-on-Don, Minsk, Tashkent, the airline "Cubana de
Aviacion" in Havana.
The next stage in development (for 1980 - 1988)
included interactive systems SP ATB-1, SP ATB-2, SP
EAT, which were installed in many airports. The listed systems
received high government estimation - The State premium of the
Council of Ministers of USSR for 1990.
The packages "LOTOS-1" (1990) and
"LOTOS-2" (1993), developed for the airline "LOT"
(Warsaw, Poland), inherited the best features of previous releases.
They took into account the technological requirements of
exploitation of modern aviation equipment (BOEING,
ATR, A-300) and experience of foreign computer systems
- MAXI MERLIN (US AIR), SCEPTRE SYSTEM (AIR LINGUS,
DUBLIN AIRPORT), DANIEL (USA), SILICON
SP RUSLAN is intended for automation of data
support of the process of technical exploitation of aviation
Therefore SP RUSLAN users are the
specialists of aircraft depot of airlines and also broad audience of
persons by and large bound up with organization of usage of aircraft
fleet - flights scheduling department, finance department, cargo
SP RUSLAN has no limitations on used types
of aircraft (domestic and foreign production) and allows organizing
all kinds of account for any number of components for each type of
aircraft. The features of a certain airline are being set up by
program parameters on the subject of installation.
SP RUSLAN is designed as a multi-level
system of modular architecture. SP RUSLAN includes a number
of independent automated systems (AS) - see figure below,
which are compatible in structure and contents of data and operate
in unified information and computation medium. For the entire SP
RUSLAN the unified technology of development, maintenance and
installation is used.
AS "Equipment" is intended for automation of
account and control of resource status of an airplane, engines,
auxiliary power plants and aggregates, registration of their
movement and changes of service conditions.
AS "Equipment" includes 8 modules and provides the
possibility to control the database and to show resource statuses of
the airplane, engines and aggregates.
AS "Control" is intended for automation of
functions of account of service conditions, analysis and control of
usage of the aircraft fleet.
"Control" provides the following possibilities:
· analyzing data about scheduling of departures and statuses
· collecting data about
usage of aircraft in different temporary and information
· preparing data about
exploitation of aircraft pursuant to the forms 34, 36 and 37 (
required by the State committee on statistics of Russian Federation
for Civil aviation).
includes 7 modules.
AS* "Maintenance" (under development
now) is intended for automation of operations of planning,
assigning, logging and controlling in technical maintenance of
aircraft, including assignment and account of execution of
"Maintenance" performs the functions of cataloging and execution
control of documents, received by the airline or issued
independently, related with structure and semantics of information
and organization of technical maintenance.
AS "Reliability" is intended for processing
data about failures and malfunctions of airplanes, engines,
auxiliary power plants and aggregates. The system provides
facilities for reliability analysis of the work of aviation
equipment in different aspects - for groups of equipment, for codes
ATA - 100, for different types of aircraft and a separate aircraft.
Besides AS "Reliability" calculates reliability indices for
different periods of time, prepares data to submit to the structures
of state supervision for the air safety. The functions of the system
are implemented in 7 modules.
AS "Planning" supports preparation of the
schedules of aircraft usage; analysis and control of requirements of
the rules of aircraft maintenance. AS "Planning" allows
forming the long-term and operative schedules of using the aircraft
fleet. The problems of planning are being solved by means of
imitative statistical models of process of technical exploitation of
aircraft. These algorithms optimize the schedules of aircraft usage
in different temporary slices with sets of different conditions,
where the problem of planning is being solved by multi-criteria
method in terms of general scheduling theory.
AS "Material and Technical Supplies" (AS
MTO) automates storage accounting, informs about receipt,
consumption and availability of supplies in the airline, watches the
level of not reducing reserve, compiles an annual requirement. For

AS "Add-ons" is intended for processing data
about add-ons (assigned, executed and not executed) for a certain
aircraft and aircraft type as a whole.
The system contains data
for the whole period of exploitation of each aircraft of the
The module "System" is intended for
installation of SP RUSLAN on a certain subject and creation
of reference sections of DB, containing characteristics of the
company and other normative data.
Today SP RUSLAN operates in JSC
AEROFLOT on IBM9672. RA-5, ADABAS v.6.3,
NATURAL v.2.3, OS/390, in "Ural Airlines" on
computer COMPAREX. In the airline LOT the system
LOTOS (the clone of SP RUSLAN designed for a Polish
airline) operates on IBM - S/390 in medium ADABAS
v.6.3, NATURAL v.2.3, OS/390, i.e. practically on
current versions of software products of the companies SOFTWARE
AG and IBM.
So, for installation of SP RUSLAN functions
the selection of mainframe as the center of data processing
is mostly important. Accordingly the application software is
oriented on usage of CRT terminals at workstations and,
therefore, restricted set of graphical means. In conditions of
repeated execution of operations of updating the DB the restricted
graphic capabilities of CRT terminals are not severe lacks
from the point of view of ergonomics. At the same time lacks of the
mentioned displays become apparent at obtaining the information in
color graphic forms, and also at opening-up the printed reporting at
SP RUSLAN, basing on the software of
corporation SOFTWARE AG, uses PC workstations of
LAN. For such workstations is provided:
· possibility of working with transactions of SP
· printing the documents,
generated in the system, at printers, connected to PC
· processing data from SP
RUSLAN by means of PC for obtaining colored graphic
· connection with systems
operating on PC for transfer to / obtaining from them the
Providing the listed capabilities should be
considered as the first step on paths to implement interfaces in
client / server architecture for the SP RUSLAN users.
The process of SP RUSLAN installation
includes several steps. At the first step the operating system, the
system of teleprocessing, package of tool software and DBMS must be
generated. Then the installation of three base subsystems AS
"Equipment", AS "Control" and module "System" must
be executed. At the end the remaining automated systems AS
"Maintenance", AS "Reliability", AS "Planning",
AS MTO must be installed.
RUSLAN is designed in such a manner that allows maintaining
up to 15 airlines and their branches in one data-processing
center. SP RUSLAN is a developing software product, its
functional capabilities permanently expand, and also is being raised
the level of information tools.
At present the following tasks are being
· a number of economic
· organization of distributed
processing of data received from SITA and AFTN
· including into SP RUSLAN
medium workstations of users from different airline services
· control of aircraft maintenance at
· improvement of users'
interfaces on the basis of programmatic components tendered by
corporation SOFTWARE AG.
In summary it is necessary to mark, that
SP RUSLAN is an effective tool of control of exploitation of
aircraft fleet. Software, used by SP RUSLAN, provides modern
airlines practically unlimited capabilities in escalating amount of
processed data, usage of remote processing, dilating of the system
functional structure and its "openness" for interplay with other
software used in the airlines. The DBMS ADABAS is effectively
used for processing large data arrays, and also for plenty of
simultaneously working users. ADABAS is designed and
optimized so that to provide maximum performance for applications of
critical importance, using rather small computing resources. SP
RUSLAN, designed in NATURAL, is easily scaled and
exported on to other platforms, because ADABAS and
NATURAL are compatible with all basic computing platforms.
Pursuant to policy "ADABAS and NATURAL forever" SOFTWARE AG
continues to develop these products, providing their integration to
the modern Internet technologies.
Today there are SP RUSLAN versions, functioning in
the medium of operational systems OS/390, LINUX, Microsoft
Windows NT, Microsoft Windows XP.
The last achievements in rendering informational
services for support of technical exploitation of aircraft fleet are
based on ASP-technology, which makes it possible to reduce
expenditures of airlines on purchase and exploitation of expensive
software product in many times and, therefore, to increase
considerably the efficiency of its usage.
At present SP RUSLAN is being exploited in
the URAL AIRLINES, AEROFLOT, PERM AIRLINES in Russia and in
the airline LOT (Warsaw, Poland).
