Abstract: In this work we present the science portal that is being developed to be used for the Dark Energy Survey (DES). It is a web-based tool that integrates several tools to access data and advanced science products, monitor the progress of the survey and data reduction, a broad range of science algorithms in a user-friendly interface. Here we focus on the capabilities of the Science Portal to host tools that generate and analyze simulations of the stellar population in the Milky Way (MW). This tool (AddStar) was employed in the recent paper by Rossetto et al. (2011) where the expected resolved stellar sample of DES was simulated. This simulation led to forecasts on how DES will be able to explore the MW structure and composition. In this work we also discuss the possible application to other large area surveys to make similar predictions. AddStar in conjunction with other scientific tools in the Science Portal can add artificial objects such as a spheroidal galaxy with a complex SFH or a globular cluster with an associated tidal tail. This set of tools creates a simulated sky with realistic conditions enabling the user to make accurate predictions for satellite galaxies discovery efficiency.
