IDEF0 Glossary

act
Perform the actions necessary to achieve the goal. These may include control manipulations, utterances, etc.
action directives
Decisions that can be acted on directly. actor factors
Factors (properties, attributes, characteristics) that affect actor behavior. For human actors, these include - knowledge (declarative, procedural) - inherent capabilities and limitations - memory - motivation - workload - level of alertness - fatigue - level of authority - etc. For machine actors, these include - knowledge (declarative and procedural) - functional capabilities and design limitations - operational state (operational, inoperative) - etc.
actor roles & responsibilities
The roles and responsibilities for the respective actors in performing this function.
AgendaManager
A computational aid to facilitate management of the flightdeck agenda.
agendas: actor assignments
The assignments of actors to this function.
agendas: goal
The goal to be achieved.
agendas: resource allocations
The allocation of resources to this function.
aircraft control information
Control information from the flightdeck to the aircraft and its subsystems.
aircraft information
Information about the state of the aircraft and its subsystems, such as altitude, fuel flow, etc.
alternative scenarios
Different courses of future events, including alternative courses of actor action, that could influence the future situation.
assess function
Assess the status of this function: how well it is being performed, what the future prospects look like, and the likelihood that the goal will be achieved.
coordinate actors
Coordinate the activities of the actors assigned to perform the function. Decide what roles and responsibilities each actor will have in performing the function.
decide/plan
Decide on what actions to perform immediately to achieve the goal, or plan what to do in the future. Planning may yield subgoals derived from the goal. These will be added to the actors' agendas.
derived goals
These are (sub)goals derived from other goals through planning, decision making, and problem solving functions.
environment information
Information from and about the environment to the flightdeck, including ATC queries and clearances.
environmental factors
Factors in the aircraft and flightdeck environments that affect flightdeck activities, including weather conditions, turbulence, illumination, temperature, etc.
flightdeck information
Information that passes from the flightdeck to the environment, including responses and acknowledgements to ATC, etc.
function status assessments
Assessments of function status: actor performance (speed, accuracy), progress, liklihood that the goal will be achieved, etc.
maintain situation models
Update and exercise each actor's situation model. Each actor has an internal representation of the current state of the world and at least human actors can project their models into the future. Maintenance of these models is driven by the need for performing specific functions.
observable actor actions
Actor actions that can be sensed by other actors.
situation models
The actors' situation models. A situation model is an internal representation of the past, present, and (projected) future state of the the environment, the aircraft, and the flightdeck. Each actor maintains his/her/its own situation model, which may or may not be complete or accurate and may or may not be consistent with the models of other actors.
