             abstract = "In the process of building a new spacecraft, one of the earliest 
                         issues the design team has to face is to define its mechanical and 
                         electrical architecture. In this context, the choice of where to 
                         place the spacecraft´s electronic equipment is probably one of the 
                         most complex task to be addressed, since it involves taking into 
                         account simultaneously many factors, such as the spacecraft´s 
                         required position of mass center, moments of inertia, equipment 
                         heat dissipation, electromagnetic interference and integration and 
                         servicing issues before launch, among others. Since this is a 
                         multidisciplinary task, the early positioning of the spacecraft´s 
                         equipment is usually done manually by a group of system engineers, 
                         heavily based on the their experience. Coupled to an analysis 
                         stage, where the system´s performance and constraints are 
                         verified, the spacecraft´s equipment layout definition is an 
                         interactive process that takes time and hence, as soon as a good 
                         feasible design is found, it becomes the baseline. This precludes 
                         a broader exploration of the conceptual design space, which may 
                         lead to a suboptimal solution, or worse than that, to a design 
                         that will have to be modified later on in the development process, 
                         impacting in schedule and costs. Recently, it has been shown the 
                         potential benefits of process automating the spacecraft´s 
                         equipment layout conception, using optimization techniques. In 
                         this paper it is shown the concept and early results of an 
                         ExcelŽ-based tool for multidisciplinary spacecraft equipment 
                         layout conception. This approach provides the system engineering 
                         team an efficient and easy to use way to explore the layout 
                         conceptual design space. A particular case study is run where 
                         results are shown for the positioning of equipment considering 
                         three objectives: i) position of system´s mass center ii) 
                         equipment heat dissipation density and iii) proximity of equipment 
                         by similarity of sub-system, in a multiobjective approach. After 
                         the Pareto set is found, the problem of decision making is also 
                         addressed for choosing a suitable solution to be implemented.",
