This is an award to support research on processes and systems that produce multivariate data and are subject to changes in performance, some of which are upsetting and that may be avoided or better dealt with if they could be anticipated. The statistical method for classifying upset conditions termed "discriminate upset prediction" involves use of current measurements as predictors of future conditions rather than using them only to characterizing the current state. The discriminate upset prediction process involves finding the parameter or parameters that best characterize a future upset condition and which may therefore serve to activate responsive measures to avoid the upset. Preliminary feasibility studies involving a suspended growth biological wastewater treatment process and the operation of a waste disposal facility have been conducted. The possibility of being able to predict a future upset in a process operating normally by examining current operating records would be of great value in assuring consistent and reliable operation of facilities that affect environmental quality. Results from this research may be applied in engineering design relating to the operation of treatment processes for water and wastewater treatment, other environmental engineering applications and manufacturing, in general.

这是一个奖项，旨在支持对产生多变量数据并受性能变化影响的过程和系统的研究，其中一些令人不安，如果可以预见，可能会避免或更好地处理。用于分类扰乱状况的统计方法称为“区分扰乱预测”，涉及使用当前测量作为对未来状况的预测，而不是仅使用它们来表征当前状态。识别翻转预测过程涉及找到最能表征未来翻转状况的一个或多个参数，并且因此可用于激活响应措施以避免翻转。已经进行了初步的可行性研究，涉及悬浮生长生物废水处理工艺和废物处理设施的运作。能够通过检查当前运行记录来预测正常运行过程中未来的混乱情况的可能性，对于确保影响环境质量的设施的一致和可靠运行将具有重要价值。这项研究的结果可以应用于与水和废水处理的处理过程的操作有关的工程设计、其他环境工程应用和一般的制造。
