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
Enabling Connectivity across a Dispersed Landscape
North West Redwater (NWR) intended to build, manage and operate a new bitumen refinery. The new refinery was being built across six square kilometers and would include over 100 contracting companies participating in the construction phase of the project. NWR wanted to provide connectivity to the 100 contracting companies over a dispersed remote area in order to simplify the contractor onboarding process, decrease operating costs, and control the project schedule.

Case Study
Improve Postal Mail and Package Delivery Company Efficiency and Service
Postal mail and package delivery company wanted to replace legacy yard management system, increase inbound and outbound yard velocity, improve priority parcel delivery time and accuracy, reduce workload and overtime, reduce driver detention and measure performance and utilization of yard resources.

Case Study
UAV for Construction Sites
The Swiss power company Axpo is building a new, underground pumped storage plant – the largest in the country – in the Canton of Glarus. In the future, the plant will guarantee the future electricity supply to northeastern and central Switzerland. The plan is for the plant to pump water from Lake Limmernsee back up to Lake Muttsee – an altitude difference of 630 metres – where it can be used again to generate electricity when required. This large-scale project, which involves investment costs of around 1.7 billion euros and is expected to take the best part of five years to complete, will employ up to 500 people at various construction sites. The plant should start to deliver electricity in 2015/2016. Hundreds of thousands of cubic metres of soil and rock will have to be removed to build the tunnels and caverns for the pumped storage plant. Most of this spoil will be transported to the Muttenalp mountain by cable car and used to build the dam, which will be more than a kilometre long and rise to a maximum height of 36 metres. The rest of the material will be deposited in front of the existing Limmern dam. The company needs to survey the surrounding before implementing the project.
