LSST将在10年的时间里，对超过18000平方度的南部天空进行多色、多时期的观测。它将产生一个数PB的天体物理来源的图像和目录档案，从中可以进行各种高精度的统计研究。为了实现这些目标，LSST项目开发了一套建模和仿真工具，用于验证LSST系统的设计和交付组件将产生具有所需统计特性的数据产品。在本文中，我们描述了LSST模拟框架的开发和使用，包括生成针对性贸易研究的模拟目录和图像，模拟LSST的观测节奏，创建测试数据校准程序的大规模模拟，以及使用端到端图像模拟来评估系统的整体性能。
The LSST will, over a 10-year period, produce a multi-color, multi-epoch survey of more than 18000 square degrees of the southern sky. It will generate a multi-petabyte archive of images and catalogs of astrophysical sources from which a wide variety of high-precision statistical studies can be undertaken. To accomplish these goals, the LSST project has developed a suite of modeling and simulation tools for use in validating that the design and the as-delivered components of the LSST system will yield data products with the required statistical properties. In this paper we describe the development, and use of the LSST simulation framework, including the generation of simulated catalogs and images for targeted trade studies, simulations of the observing cadence of the LSST, the creation of large-scale simulations that test the procedures for data calibration, and use of end-to-end image simulations to evaluate the performance of the system as a whole.
