; Operational Acceptance Testing ( OAT ): Also known as operational readiness testing, this refers to the checking done to a system to ensure that processes and procedures are in place to allow the system to be used and maintained.

Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS system and implement the next generation of GPS III satellites and Next Generation Operational Control System ( OCX ).

Operational definitions are also used to define system states in terms of a specific, publicly accessible process of preparation or validation testing, which is repeatable at will.

* Operational semantics, in which the meaning of a system is expressed as a sequence of actions of a ( presumably ) simpler computational model.

There are four roles within a business Management system: Business Leader, Process Owner, Operational Manager, and Process Operator.

Operational expense is all the money the system spends in order to turn inventory into throughput.

Operational semantics are classified into two categories: structural operational semantics ( or small-step semantics ) formally describe how the individual steps of a computation take place in a computer-based system.

Albus co-invented the Real-Time Control System ( RCS ), a reference model architecture that has been used over the past 25 years for a number of intelligent systems including the NBS Automated Manufacturing Research Facility ( AMRF ), the NASA telerobotic servicer, a DARPA Multiple Autonomous Undersea Vehicle project, a nuclear Submarine Operational Automation System, a Post Office General Mail facility, a Bureau of Mines automated mining system, a commercial open architecture machine tool controller, and numerous advanced robotic projects, including the Army Research Lab Demo III Experimental Unmanned Ground vehicle.

In 1997, when Boeing proposed to extend ETOPS authority for twins to beyond 180 minutes, Airbus proposed to replace ETOPS by a newer system, referred to as LROPS or Long Range Operational Performance Standards, which would affect all civil airliners, not just those with a twin-engine configuration with more than 180 minutes ETOPS.

* Operational Technology, industrial control system environment

:* Operational distribution or deployment: Where will the system be used?

:* Operational life cycle: How long will the system be in use by the user?

:* < big > The system itself does not actually do what it says it is doing .</ big > Operational Fallacy

Operational Prototyping was proposed by Alan Davis as a way to integrate throwaway and evolutionary prototyping with conventional system development.

SSM has been characterized as a learning system, part of a new paradigm for Operational Research and as a front-end for information system design.

* Safety: the IATA Operational Safety Audit is an internationally recognized and accepted evaluation system designed to assess the operational management and control systems of an airline.

In 1989, the system began its Initial Operational Test and Evaluation ( IOT & E ) series of tests.

Usage models, so Markov chains, are mainly constructed of 2 artifacts: the Finite State Machine ( FSM ) which represents all possible usage scenario of the tested system and the Operational Profiles ( OP ) which qualify the FSM to represent how the system is or will be used statistically.

Operational since 1978 and globally available since 1994, GPS is currently the world's most utilized satellite navigation system.

Operational semantics loosely corresponds to interpretation, although again the " implementation language " of the interpreter is generally a mathematical formalism.

* Operational Analysis, more generally called " Operational Research ": a branch of applied mathematics

Zarya FGB ФГБ-Функциональный Грузовой Блок, English: Functional ( or Operational ) Cargo Block ( or Module ) holds 5, 500 kg and the Zvezda Service module holds 860 kg, however, it is generally preferred to keep the main thrusters on Zarya and Zvezda in reserve, as they have finite lifespans.

Operationally, Fire Police Units and Operational Support Units are generally considered to be equivalent, and are well valued by both the operational Firefighters and the New Zealand Police.

MTTR is often part of a maintenance contract, where a system whose MTTR is 24 hours is generally more valuable than for one of 7 days if mean time between failures is equal, because its Operational Availability is higher.

* Operational rules for international emissions trading among parties to the Protocol and for the CDM and joint implementation ;

* The Rugby Football League's ( RFL ) Operational rules

: Documentation of the data requirements and structural business process rules of the Operational View.

The applicable rules are known as ETOPS ( Extended-range Twin-engine Operational Performance Standards ).

Operational systems are optimized for preservation of data integrity and speed of recording of business transactions through use of database normalization and an entity-relationship model.

* Operational database

Operational requirements are needed to be met by a database in order to effectively support an application when operational.

* Tactical and Operational Modeling: This uses the same approach as for strategic modeling, but focuses on tactical business units-expanding into tactical attribute detail and later operational attribute detail for physical database generation and installation.

The aim of the German XIX corps was to seize the fortress in order to prevent elements of a divided Narew Operational Group under General Młot-Fijałkowski from retreating southwards and joining the rest of the Polish forces.

In order to conduct an EU military crisis management operation, an Operational Headquarters ( OHQ ) is nominated by the appropriate EU Council decision.

* Unidragon Mining and Development Corporation ( Not Operational due to Cease and desist order by MGB )

* Baotong Mining Corporation ( Not Operational due to Cease and desist order by MGB )

The MTP program was established to ensure the operational continuity between the end of the successful Meteosat Operational Programme in 1995 and Meteosat Second Generation ( MSG ), which came into operation at the start of 2004 using improved satellites.

The case is then validated by a third party agency, called a Designated Operational Entity ( DOE ), to ensure the project results in real, measurable, and long-term emission reductions.

Operational processes should also be identified and addressed during this phase to ensure that all scenarios are identified.

* National Operational Model Archive and Distribution System ( NOMADS ) is a NOAA Web-services based project providing both real-time and retrospective format independent access to climate and weather model data.

As most data is now digital, this opens the way for extra functionalities to be embedded in the modern Operational Display System, such as trajectory prediction, conflict warnings, traffic flow management, arrival optimisation, etc.

* Operational data store, an intermediate data warehouse for databases

* Operational Risk Consortium is a consortium that collects and analyzes operational risk loss data for the insurance industry.
