                         ecol{\'o}gicos, etc.) em subsistemas que trabalham em 
                         condi{\c{c}}{\~o}es severas. Por essas raz{\~o}es s{\~a}o 
                         projetados atrav{\'e}s de diversos processos, usando muitos 
                         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 
                         quais operam. Para suprir essa evolu{\c{c}}{\~a}o, as 
                         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 
                         t{\~a}o d{\'{\i}}spares, al{\'e}m de n{\~a}o haver uma 
                         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

                         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 
                         inter-ferramentas aqui desenvolvido, {\'e} poss{\'{\i}}vel 
                         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 
                         atitude de um microssat{\'e}lite. As conclus{\~o}es sintetizam 
                         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 
                         param{\'e}tricas. ABSTRACT: Systems such as satellites, 
                         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
