在过去的二十年里，许多CAPP（计算机辅助工艺设计）系统得到了发展。从变式工艺规划到生成式工艺规划，已经取得了很大的进展。然而，由于所涉及问题的复杂性，仍然没有真正的生成性流程规划解决方案。此外，为了使生成系统在生产中真正有用，必须解决集成问题。本文介绍了一个集成工艺规划项目（IPPS）。我们重点介绍了使用ALPS（一种用于工艺规范的语言）对设置选择和工艺计划表示进行公差分析。

THE PAST TWO DECADES HAVE WITNESSED THE DEVELOPMENT OF MANY CAPP (COMPUTER AIDED PROCESS PLANNING) SYSTEMS. FROM VARIANT PROCESS PLANNING TO GENERATIVE PROCESS PLANNING, GREAT PROGRESS HAS BEEN MADE. HOWEVER, DUE TO THE COMPLEXITY OF THE PROBLEMS INVOLVED, THERE IS STILL NO A TRUE GENERATIVE PROCESS PLANNING SOLUTION. FURTHER, TO MAKE A GENERATIVE SYSTEM TRULY USEFUL IN PRODUCTION, THE ISSUE OF INTEGRATION MUST BE ADDRESSED. IN THIS PAPER, WE INTRODUCE AN INTEGRATED PROCESS PLANNING PROJECT (IPPS). WE FOCUS ON THE USE OF TOLERANCE ANALYSIS FOR SETUP SELECTION AND PROCESS PLAN REPRESENTATION USING ALPS (A LANGUAGE FOR PROCESS SPECIFICATION).
