过程控制与优化
概述
过程控制和优化 (PCO) 是在不违反过程约束的情况下调整过程以维持或优化一组指定参数的学科。 PCO 市场受到对节能生产流程、安全和安保问题的需求不断增长以及能够可靠预测流程偏差的物联网系统开发的推动。从根本上说,可以调整三个参数以影响最佳性能。 - 设备优化:第一步是通过检查运行数据以识别设备瓶颈来验证现有设备是否被充分利用。 - 操作程序:操作程序可能因人而异或因班次而异。工厂的自动化可以提供很大帮助。但是,如果操作员控制并手动运行工厂,自动化将无济于事。 - 控制优化:在典型的加工厂,例如化工厂或炼油厂,有数百甚至数千个控制回路。每个控制回路负责控制过程的一部分,例如保持温度、液位或流量。如果控制回路没有正确设计和调整,则过程会低于其最佳值。该过程的操作成本将更高,并且设备会过早磨损。为了使每个控制回路以最佳方式运行,识别传感器、阀门和调整问题很重要。已充分证明超过 35% 的控制回路通常存在问题。持续监控和优化整个工厂的过程有时称为绩效监督。

Case Study
HEINEKEN Uses the Cloud to Reach 10.5 Million Consumers
For 2012 campaign, the Bond promotion, it planned to launch the campaign at the same time everywhere on the planet. That created unprecedented challenges for HEINEKEN—nowhere more so than in its technology operation. The primary digital content for the campaign was a 100-megabyte movie that had to play flawlessly for millions of viewers worldwide. After all, Bond never fails. No one was going to tolerate a technology failure that might bruise his brand.Previously, HEINEKEN had supported digital media at its outsourced datacenter. But that datacenter lacked the computing resources HEINEKEN needed, and building them—especially to support peak traffic that would total millions of simultaneous hits—would have been both time-consuming and expensive. Nor would it have provided the geographic reach that HEINEKEN needed to minimize latency worldwide.

Aruba Cuts the Core with Microsoft Lync
Aruba's IT team purchased a telephony system which is going end-of-life and this would become a bottleneck to growth. While they began investigating modern PBX systems, they were also considering put their own Wi-Fi infrastructure to work by adopting a Unified Communications and Collaboration solution.
