9309270 Runger The objective of this work is a comprehensive, optimal solution to the design of an adaptive statistical process control (SPC) algorithm. The work will develop adaptive algorithms for SPC that optimize the fundamental design parameters of an SPC algorithm. The system is adaptive in the sense that it has the capability to dynamically vary elements, such as sampling intervals and sample sizes, based on the deviations of the measured variable from its target value. One phase of the research will use a semi economic model to relate total system cost to system design parameters. This research will optimize adaptive SPC systems. Process control in manufacturing operations will be improved by these techniques. The result is the ability to identify a process which is off target much faster, without additional false alarms, and without additional samples. This translates to a more powerful process control system, which results in lower manufacturing costs and better quality. A software system which will provide guidance in designing an adaptive SPC system will provide a means of quickly transferring a significant, new technology to industry.

小行星9309270 这项工作的目标是一个全面的，最佳的解决方案，设计的自适应统计过程控制（SPC）算法。 这项工作将开发自适应算法的SPC优化的SPC算法的基本设计参数。 该系统是自适应的，因为它有能力动态地改变元素，如采样间隔和样本大小，基于测量变量与其目标值的偏差。 研究的一个阶段将使用一个半经济模型，将系统总成本与系统设计参数联系起来。 这项研究将优化自适应SPC系统。 这些技术将改善生产操作中的过程控制。 结果是能够更快地识别偏离目标的过程，而没有额外的假警报，并且没有额外的样本。 这转化为更强大的过程控制系统，从而降低制造成本并提高质量。 一个为设计自适应SPC系统提供指导的软件系统将提供一种将重要的新技术快速转移到行业的方法。
