1.1 Introduction
Avionics systems are composed of multiple applications, various functions, and diverse
equipment, with typical complex systemic characteristics featuring multiobjective, multicap-
ability, and multiprocess organization. The known complicated systems comprise a wide
range of objects that differ in shape, content, capability, as well as behavior, which have
some direct, indirect, and potential connections with other objects, and the capability, activ-
ity,aswellasenvironmentofoneobjectwillexertdifferentlevelsofimpactontheotherob-
jects. For complex systems, the way to recognize these different levels of effect, identify the
correlations among them, solve problems and defects in the system, and increase the proba-
bilityandeffectivenessofachievingthedesiredgoalshasbecomethecoreareaofthecurrent
research on complex systems.

1.1 Introduction
Forthemultiobjective,multicapability,andmultiprocessfeaturesofcomplexsystems,cur-
rent research mainly focuses on two different thoughts: one is big data technology, and the
other is the integration technology.
Big data technology covers data collection, statistics, mining, reasoning, and cognition in
thesystemoperationprocess.Onthebasisofalargeamountofdatageneratedbythesystem
operating environment, process, and status, it establishes activity patterns and data associa-
tion; identifies the direct, indirect, and potential connections based on the above data; ex-
plores the inner relationship, weight, and influence; and also accumulates system capacity,
knowledge as well as cognition by logic, condition, and status reasoning. In other words,
bigdatatechnologyisnotamethodthatemploystheforwardanalysisandsolutionthoughts
ofthelogicbutisanapproachthatanalyzestherunningdataandreasonstherelationshipof
theobjects.Therefore,themainproblemsregardingbigdatatechnologyare:thecomprehen-
sivenessofdatacoverage;compositionofdataandvalidityofrange;validityandaccuracyof
theassociateddata;validityofthereasoning-basedknowledgelibrary;andvalidityofknowl-
edge mining cognition.
This integration technology is a top-down forward design technology for system organi-
zation and design. In other words, it targets the complex capability, activities, and environ-
ment of the objects; constructs applications, tasks, and purposes of systemic integration;
builds capability, functions, and process of the systemic integration; establishes resources,
operation, and running of the systemic integration; as well as meets the expected goals of
thesystem.Forcomplexsystems,problemsoflackofknowledge,recognition,andconsider-
ation do exist in the current forward organization and design process. However, with the
continuous improvement of recognition, and the enhancement of the information environ-
ment organization and processing capability, the system organization will become more
comprehensive, system processing will be deeper, and the results of the system will be
moreaccurate.Especiallywiththerapiddevelopmentandpopularizationofartificialintelli-
gence technology, organization, processing, and reasoning of these complex systems will be
moreprecise,whichcangreatlyreducetheuncertaintyofthefactorsofcomplexsysteminte-
gration and also effectively improve the validity of the results of the integration systems.
Theavionicssystemiscomposedoftaskorganizations,functionalorganizations,andcom-
plex equipment related to the flight environment. There are different flight tasks and pur-
poses in different categories of flight environment; likewise, there are different processing
logic and qualities in different system functions, and there are different operation modes

Avionics system integration represents the system organization and integration, which is
orientedtosystemapplications,functions,andequipment.Itsmainpurposeistoimprovethe
operational capability and effectiveness of system applications through a multiple

tion and integration of the complex system environment; to enhance the system resource
sharing and effectiveness through multiple resources organization and integration of
complex equipment types; which ultimately improves effectiveness, efficiency, and perfor-
mance of the overall system.
Orientedtotheneedsofsystemapplicationobjectives,systemcapabilities,andtheequip-
ment operations, avionics system integration technology consults the organization of appli-
cation tasks, system functions, and equipment resource, and takes the means of system
integration technology of activity integration, process integration, information fusion, as
well as resource sharing. Finally, it can achieve flight process optimizationdenhancing the
application objectives, expanding the effect scope, and improving operational efficiency;
anditachievestheoptimizationofsystemfunctionalprocessingdenhancingsystemcapabil-
ities, expanding the processing range, and improving the processing efficiency; and it opti-
mizes the use of equipment resourcesdenhancing resource sharing, reusing the operation
process, and improving the confidence of results. Ultimately, it achieves the goal of avionics
systems integration.
1.1.1 The concept of avionics systems
Initially, avionics refers to a subject that applies electronic technology in the field of aero-
nautics (mainly aircraft). With the development of electronic technology, especially digital
electronic technology, information technology, as well as computer technology, the role
andcapabilityofavionicsarenolongerconfinedtotherealizationandpromotionoftheorig-
inal instrumental capability of the aircraft. Instead, oriented to the overall flight capability
anditsorganization,itformstheflightcapabilityorganizationandrealization,flightprocess
guidance and control, as well as aircraft condition surveillance and management. Avionics
systems have transformed from providing aircraft capability support to task organization
and management. Therefore, the current avionics are generally referred to as avionics
systems.
As related technologies develop, electronic technology and computer technology are
deeplyinvolvedinthecapabilityandrealizationprocessoftheaircraftbodyandtheengine.
For instance, deformation control of the aircraft and monitoring of engine fuel injection
have gone beyond the scope of the flight task system. Currently, some literary works refer
toanyfieldandactivitycapabilitiesrelatingtotheaircraftelectronicsystemsastheavionics
system, but most of the works consider the avionics system as the flight task system itself.
This book mainly defines avionics as referring to the flight task-oriented organization and
management.
