The objective of this research is to investigate a mathematical tolerance allocation approach for design based on desired product specification and known manufacturing process variability. The allocation criteria will be compared to the tolerance analysis based on Monte Carlo statistical methods used in the VSA (Variation Simulation Analysis) commercial package. Once it is understood how the distributions are combined, a formal tolerance allocation methodology will then be completed. This approach is a more empirical approach of pre-determining allowable part tolerance as opposed to the "what-if" tests conducted on the VSA software

本研究的目的是探讨一种数学公差分配方法的基础上所需的产品规格和已知的制造工艺的可变性设计。将分配标准与基于VSA（变化模拟分析）商业包中使用的Monte Carlo统计方法的公差分析进行比较。一旦理解了分布是如何组合的，就完成了正式的公差分配方法。与VSA软件上进行的“假设”测试相反，这种方法是一种更经验的方法，用于预先确定允许的零件公差
