                         decis{\~o}es que podem influenciar todo o ciclo de vida de um

                         conjuntas, a saber: (1) Engenharia de Sistemas Baseada em Modelos 
                         (MBSE) utilizando a linguagem SysML tratada por um aplicativo 
                         denominado SatBudgets estendido e (2) Otimiza{\c{c}}{\~a}o de

                         otimiza{\c{c}}{\~a}o, evolutivo, denominado MGEO. O problema de

                         apresentado como estudo de caso limitado ao cen{\'a}rio 
                         biŽdimensional para fins de escopo. Este problema ocorre 
                         tipicamente durante a fase conceitual do desenvolvimento. A partir 
                         de requisitos de alto n{\'{\i}}vel da arquitetura de miss{\~a}o 
                         da Plataforma Multimiss{\~a}o (PMM) do INPE, {\'e} feita a

                         envolveu a interopera{\c{c}}{\~a}o e reuso de artefatos entre 
                         duas ferramentas comerciais: uma de Gest{\~a}o de Requisitos e 
                         outra para Modelagem SysML. A metodologia adotada neste trabalho 
                         poder{\'a} ser estendida para uma grande variedade de problemas

                         Nowadays there has been a significant increase in number and 
                         complexity on board satellites which requires improvement in 
                         methods and processes in Space System Engineering. This 
                         dissertation focuses on one such aspect, more specifically 
                         regardŽing the interoperability of tools for computational 
                         engineering environments, here named Optima, which support the 
                         design of satellites and have to meet constraints on time, cost 
                         and quality, among others. This need is more remarkable in the 
                         conceptual design phase since it involves decisions that may 
                         infiuence the entire system life cycle. Computing applications 
                         allow the study of scenarios involving simulations, choice of 
                         viable system architectures and complex optimization calculations 
                         on the various disciplines of space systems engineering. 
                         Typically, this requires dealing with interoperability in data 
                         exchange between the various traditional software tools of each 
                         particular discipline which may hinder actions on concurrent 
                         engineering. In order to contribute to this scenario, this work 
                         deals jointly with two approaches, namely: (1) Model-Based Systems 
                         Engineering (MBSE) using the SysML language handled by an extended 
                         application called SatBudgets and (2) Multidisciplinary Design 
                         Optimization (MDO) using a evolutionary algorithm called MGEO 
                         already available. The layout problem of on-board equipments in 
                         satellites is presented as a case study limited to a 
                         two-dimensional scenario for scope reasons. This problem typically 
                         occurs during the conceptual phase of development. Starting from 
                         highlevel requirements of the mission architecture for the 
                         Brazilian Space Multimission Platform (MMP), the decomposition and 
                         derivation of requirements that will influence the layout problem 
                         were done. From this process, three objective functions were 
                         defined for the MGEO optimization. Additionally, this process 
                         involved the interopŽeration and reuse of artifacts between two 
                         commercial tools: one for Requirements Management and another for 
                         SysML modeling. The methodology adopted here can be extended to a 
                         wide range of problems with similar application domain.",
