奥斯汀市（德克萨斯州）水和废水公用事业公司一直生产最高标准的饮用水。但随着越来越严格的法规的发展，水处理对运营商来说变得更加复杂。公用事业管理人员认识到，尽管有必要提供先进的计算机系统、仪器和传统操作培训，但仅这些要素不足以满足公用事业严格的内部优化目标。操作员还需要能够识别并迅速响应不断发展的过程问题。公用事业管理者意识到，操作人员将受益于现成的工厂特定工艺指南，并设想了一个工艺辅助系统（PAS）。 PAS以网页格式编写，旨在帮助操作员解释数据并提高他们的决策技能。它是通过深入调查操作员在常规和非常规操作期间的行为和治疗决定而开发的。PAS还将被用作培训、绩效评估和操作员问责的工具。包括5个参考文献、表、图。

The City of Austin (Texas) Water and Wastewater Utility consistently produces drinking water of the highest standards. But with the development of more and tougher regulations, water treatment has become more complex for operators. Utility managers recognized that although it is necessary to provide advanced computer systems, instrumentation, and traditional operations training, these elements alone are not sufficient to meet the utility's stringent interal optimization goals. Operators also need to be able to recognize and respond promptly to developing process problems. Utility mamagers realized that operators would benefit from readily available plant-specific process guidance and envisioned a process assistance system (PAS). Written in Web-page format, the PAS is designed to help operators interpret data and improve their decision-making skills. It was developed through in-depth investigations of operators' actions and treatment decisions during routine and nonroutine operations. The PAS will also be used as a tool for training, performance assessment, and operator accountability. Includes 5 references, table, figure.
