             abstract = "One issue the design team has to face in the process of building a 
                         new spacecraft, is to define its mechanical and electrical 
                         architecture. The choice of where to place the spacecraft´s 
                         electronic equipment is a complex task, since it involves 
                         simultaneously many factors, such as the spacecraft´s required 
                         position of center of mass, moments of inertia, equipment heat 
                         dissipation, integration and servicing issues, 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 their experience. It is an 
                         interactive process that takes time and hence, as soon as a 
                         feasible design is found, it becomes the baseline. This precludes 
                         a broader exploration of the design space, which may lead to a 
                         suboptimal solution, or worse to a design that will have to be 
                         modified later. Recently, it has been shown the potential benefits 
                         of automating the process of spacecraft´s equipment layout using 
                         optimization techniques. In this paper, a prototype of an ExcelŽ 
                         based tool for multidisciplinary spacecraft equipment layout 
                         conception is described. Provided the geometric dimensions, mass 
                         and heat dissipation of the equipment, and the available 
                         positioning area, the tool can automatically generate many 
                         possible trade-off solutions for the layout. It allows the user to 
                         set specific equipment to specific areas of positioning, and 
                         different combinations of objective functions can be used to drive 
                         the design. The features of the tool are shown in a simplified 
                         three dimensional problem.",
