             abstract = "One of the main tasks involving the development of a new 
                         spacecraft is how to distribute its electronic equipment over its 
                         structural panels. This problem is first addressed in the 
                         conception phase of the design and is traditionally carried out by 
                         a group of system engineers. It is a multidisciplinary task since 
                         structural, thermal, dynamics, and integration issues, must all be 
                         taken into account simultaneously. Usually, the initial 
                         positioning is done based on the engineers' experience, followed 
                         by an analysis stage (thermal, structural, etc.) in which the 
                         design performance and constraints are verified. This process 
                         takes time and hence, as soon as a good feasible design is found, 
                         it is taken as the baseline. This precludes a broad exploration of 
                         the conceptual design space, which usually leads to a suboptimal 
                         layout design. In this paper the main features of a 
                         multi-objective methodology are presented which were developed to 
                         automatically find solutions for a three-dimensional layout of 
                         equipment in spacecraft. It includes mass, inertia, thermal and 
                         subsystem requirements and geometric constraints using a 
                         multi-objective approach that combines CAD and optimization tools 
                         in an integrated environment. As a case study, the methodology was 
                         applied to the layout optimization of the Brazilian Multi-Mission 
                         Space Platform (MMP) equipment. The main results are presented.",
