abstract = "Sistemas como sat{\'e}lites, avi{\~o}es, autom{\'o}veis,
hospitais,cidades, entre outros, v{\^e}m se tornando cada vez
mais complexos e/ou altamente integrados. Todos integram diversas
tecnologias e lidam com fen{\^o}menos d{\'{\i}}spares
(f{\'{\i}}sicos, qu{\'{\i}}micos, biol{\'o}gicos, sociais,

modelos e grande quantidade de dados. Estes devem ser combinados,
avaliados e melhorados progressivamente, atrav{\'e}s da
experi{\^e}ncia e das modifica{\c{c}}{\~o}es de contexto nos

tecnologias de computa{\c{c}}{\~a}o e comunica{\c{c}}{\~a}o
v{\^e}m oferecendo um suporte cada vez mais amplo, originando
diversas cadeias de processos. No entanto, pouco tem sido feito no
sentido de integrar e interconectar de forma eficiente ferramentas

simbologia capaz de mapear possibilidades de arranjos de cadeias
de processos a partir de uma dada disponibilidade de software,
ferramentas e modelos. Por isso, nesta tese desenvolveu-se uma
metodologia de integra{\c{c}}{\~a}o, interconex{\~a}o e reuso
de software em um processo colaborativo no ambiente RCE e sua
aplica{\c{c}}{\~a}o {\`a} concep{\c{c}}{\~a}o de
sat{\'e}lites. Para realizar isso, partiu-se dos
princ{\'{\i}}pios da Engenharia de Sistemas Baseada em Modelos,
fazendo um levantamento geral de requisitos e conceitos, e do uso
de diferentes abordagens, dom{\'{\i}}nios f{\'{\i}}sicos e
plataformas de simula{\c{c}}{\~a}o que devem interagir
coerentemente entre si. A seguir, desenvolveram-se e integraram-se
no ambiente colaborativo ferramentas computacionais de diferentes
naturezas. Atrav{\'e}s de um diagrama de rela{\c{c}}{\~o}es

mapear subsistemas de diferentes categorias de sat{\'e}lites e
adotar pol{\'{\i}}ticas de reuso de ferramentas eficazes,
utilizando a sele{\c{c}}{\~a}o e fus{\~a}o das mesmas. Os
modelos desenvolvidos usam diferentes abordagens (f{\'{\i}}sica,
informacional, h{\'{\i}}brida, etc.) e englobam
dom{\'{\i}}nios f{\'{\i}}sicos diversos (mec{\^a}nico,
hidr{\'a}ulico, termodin{\^a}mico, etc.). No caso de estudo,
constru{\'{\i}}ram-se duas cadeias de processo referentes
{\`a}s fases iniciais (0 e A) de um subsistema de controle de

os progressos feitos em termos de sistematizar o desenvolvimento
de sistemas na fase inicial, destacando as inicia{\c{c}}{\~o}es
e avan{\c{c}}os em temas novos. Dentre os aspectos originais
destacam-se: (a) um diagrama de classifica{\c{c}}{\~a}o de
ferramentas; (b) a sistematiza{\c{c}}{\~a}o do processo de
desenvolvimento inicial; (c) a constru{\c{c}}{\~a}o de um
diagrama din{\^a}mico inter-ferramentas, com
transforma{\c{c}}{\~o}es l{\'o}gicas; (d) a
elabora{\c{c}}{\~a}o e execu{\c{c}}{\~a}o de cadeias de
processo multidisciplinares, multidom{\'{\i}}nio e
multiplataforma, de modo autom{\'a}tico para an{\'a}lises

airplanes, automobiles, hospitals, cities, among others, are
becoming increasingly complex and/or highly integrated. All of
them integrate different technologies and embrace several
phenomena (physical, chemical, biological, social, ecological,
etc.) in subsystems that work in severe conditions. For those
reasons they are designed through different processes, using
several models and a great amount of data. These models and
processes must be combined, improved and evaluated through system
life cycle, experience and context modification in which they
operate. To support this evolution there are computer and
communication technologies that offer a broad spectrum of work
possibilities that translates into different process chains.
However, little has been done in the sense of integrating and
interconnecting so diverse tools with efficiency. Besides that,
there is lack of a symbology capable of mapping linking
possibilities in process chains from a certain software (tools and
models) availability.Therefore, this thesis develops a methodology
for software integration, interconnection and reuse in a
collaborative process in the RCE environmentand its application to
the conception of satellites. To accomplish this, several
principles of Model Based Systems Engineering were adopted,
thorough concepts and requirements analysis, use of different
approaches, physical domains and simulation platforms that must
interact coherently between themselves. After this stage,
different tools were developed and integrated in the collaborative
environment whose main differential consists in remote execution.
Through a inter-tool relation diagram, it is possible to map
subsystems of different satellites and adopt efficient reuse
policies for tools, through fusion and selection. The models
developed use different approaches (physical, informational,
hybrid) and represent diverse physical phenomena (mechanical,
hydraulic, thermodynamic, etc.). As a case study two process
chainsrelated to early phases (0 and A) of a microsatellite
attitude control subsystem were developed. Conclusions synthesize
progress done in terms of systems development systematization in
early phases, highlighting initiations and advances in each new
topic proposed. Within those original topics we can quote: (a) a
tools classification diagram; (b) the systematization of the
initial development process; (c) construction of an inter-tool
dynamic diagram, with logical transformations and; (d)
construction and execution of automated multidisciplinary,
multidomain and multiplatform process chains, for parametric
analysis.",
