Process control and optimization (PCO) is the discipline of adjusting a process to maintain or optimize a specified set of parameters without violating process constraints. The PCO market is being driven by rising demand for energy-efficient production processes, safety and security concerns, and the development of IoT systems that can reliably predict process deviations. Fundamentally, there are three parameters that can be adjusted to affect optimal performance.
- Equipment optimization: The first step is to verify that the existing equipment is being used to its fullest advantage by examining operating data to identify equipment bottlenecks.
- Operating procedures: Operating procedures may vary widely from person-to-person or from shift-to-shift. Automation of the plant can help significantly. But automation will be of no help if the operators take control and run the plant in manual.
- Control optimization: In a typical processing plant, such as a chemical plant or oil refinery, there are hundreds or even thousands of control loops. Each control loop is responsible for controlling one part of the process, such as maintaining a temperature, level, or flow. If the control loop is not properly designed and tuned, the process runs below its optimum. The process will be more expensive to operate, and equipment will wear out prematurely. For each control loop to run optimally, identification of sensor, valve, and tuning problems is important. It has been well documented that over 35% of control loops typically have problems. The process of continuously monitoring and optimizing the entire plant is sometimes called performance supervision.
CenturyLink wanted to accelerate design and delivery of IP-based enterprise services, drive all processes from a central catalog for improved service agility and position CenturyLink for SDN/NFV with an open, standards-based solution.
Due to the needs of its service area, the new healthcare campus doubled in size. With the vast size difference between the old and new hospital, Parkland had to address several issues — the most critical being adjustments in the day-today patient care provided by its clinical staff. The sheer size of the patient floors — nearly the length of two football fields — was a challenge. That size drove caregivers from a centralized care model to a decentralized one — creating the need to change how communication and collaboration happens.
Before implementing our safety software solution, Michael Armitage, EHS Manager noted how Siemens had a lot of business units using different systems for the recording of EHS events. There was a clear need for a more efficient system for managing EHS data which would fit both client and divisional reporting requirements. The biggest issue with each business unit using a different H&S system was that a lot of them were using old databases and in some cases, Excel spreadsheets. Risk assessments, inspections and audits, method statements and training all sat separately with little or no interaction.
