设置规划是工艺规划的中间阶段，自动化设置规划构成了计算机辅助工艺规划的关键组成部分。普遍缺乏明确定义的设置计划的最优性，这一直是将自动设置规划研究进展转化为实践中真正进步的主要障碍。设置计划的最优性是一个与不确定性相关的多属性问题，而人机交互对于阐明动态设置规划环境中的最优性结构至关重要。在本文中，提出了一种由多属性效用分析和制造误差模拟驱动的定量设置计划评估系统，以达到三个目的：（1）阐明什么是设置计划的最优性，（2）提供定量评估设置计划替代方案的系统方法，以及（3）在现有的自动设置计划系统中纳入人机界面以实现其潜在价值。
Setup planning is an intermediate phase of process planning, and automating setup planning constitutes a critical component of computer-aided process planning. The common absence of a clearly defined optimality of setup plans has been a major obstacle to converting automatic setup planning research progress into real advancement in practice. The optimality of a setup plan is a multiple attributes problem associated with uncertainties, and human interaction is vital in clarifying the optimality structure in a dynamic setup planning environment. In this paper, a quantitative setup plan evaluation system driven by multiple-attributes utility analysis coupled with manufacturing error simulation is proposed to serve three purposes: (1) to clarify what is optimality of setup plans, (2) to provide a systematic method of evaluating setup plan alternatives quantitatively, and (3) to incorporate in existing automatic setup planning systems a human interface to fulfill their potential values.
