== APC Business and Professionals ==

Those responsible for the design, implementation, and maintenance of APC applications are often referred to as APC Engineers or Control Application Engineers. Usually, their education is dependent upon the field of specialization. For example, in the process industries, many APC Engineers have a chemical engineering background, combining process control and chemical processing expertise.

Most large operating facilities, such as oil refineries, employ a number of control system specialists and professionals, ranging from field instrumentation, regulatory control system (DCS and PLC), advanced process control, and control system network and security. Depending on facility size and circumstances, these personnel may have responsibilities across multiple areas, or be dedicated to each area. There are also manyMany process control service companies that can be hired for support and services in each area.

== Artificial Intelligence and Process Control ==

The use of Artificialartificial Intelligenceintelligence, Machinemachine Learninglearning, and Deepdeep Learninglearning techniques in Processprocess Controlcontrol is also considered as an advanced process control approach in which intelligence is used to further optimize operational parameters further.

OperationsFor decades, operations and Logicslogic in process control systems in oil and gas and for decadeshave arebeen based only on physics equations that dictatesdictate parameters along with operators’ interactions based on experience and operating manuals. Artificial Intelligenceintelligence and Machinemachine Learninglearning algorithms can look into the dynamic operational conditions, analyseanalyze them, and suggest optimized parameters that can either directly tune logic parameters or give suggestionsuggestions to operators. Interventions by such intelligent models leadslead to optimization in cost, production, and safety.<ref>{{Cite news |date=2016-04-06 |title=Oil and Gas, AI, and the Promise of a Better Tomorrow |language=en-US |work=[[SparkCognition]] Inc. |url=https://www.sparkcognition.com/oil-gas-ai-promise-better-tomorrow/ }}</ref>

== Terminology ==

*APC: Advanced process control, including feedforward, decoupling, inferentialsinferential, and custom algorithms; usually implies DCS-based.

*ARC: Advanced regulatory control, including adaptive gain, override, logic, fuzzy logic, sequence control, device control, and custom algorithms; usually implies DCS-based.

*Base-Layer: Includes DCS, SIS, field devices, and other DCS subsystems, such as analyzers, equipment health systems, and PLCs.

*BPCS: Basic process control system (see "base-layer")

*DCS: Distributed control system, often synonymous with BPCS

*MPO: Manufacturing planning and optimization

*MPC: Multivariable [[Modelmodel predictive control]]

*SIS: [[Safety instrumented system]]

*SME: Subject matter expert
