                         this work is proposed a platform for creating initial layout for 
                         the artificial satellite equipments allocation problem, 
                         considering the center of mass and the moment of inertia of the 
                         solution, as well as restrictions on the placement of each 
                         equipment. The positioning of equipments with different masses, 
                         directly influences the location of the center of mass and the 
                         moment of inertia of the satellite. Find the best layout consists 
                         of a problem of \${{"}}\$NP-Hard\${{"}}\$ nature. At 
                         satellites layouts development is also important to consider the 
                         thermal dissipation generated by the equipment and the cable 
                         connection between them. The nature-inspired meta-heuristics 
                         \emph{Ant Colony Optimization and Multi-Particle Collision 
                         Algorithm} were implemented to find optimized solutions and a new 
                         heuristic called \emph{Spatial Affinity Balancing Heuristic} was 
                         developed for this problem, based on the affinity between the 
                         equipment when good layouts are found. The Brazilian satellite 
                         ITASAT was used as the basis for the development of this work. The 
                         platform allows the introduction of knowledge a priori in the 
                         exploration process performed by the optimization algorithms, such 
                         as setting the position of certain objects and add constraints for 
                         minimal and/or maximal distances between two objects.",
