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.
AgendaManager
A computational aid to facilitate management of the flightdeck agenda.
agendas
The agendas of the actors. Literally, an agenda is a list of things to be done. In the context of this model, an agenda consists of a set of goals to be achieved, a set of functions to accomplish them, assignments of actors to functions, and allocations of resources to functions. Each actor maintains his/her/its own agenda, which may or may not be consistent with the agendas of other actors. Together, the individual agendas can be viewed as forming a single, composite flightdeck agenda.
derived goals
These are (sub)goals derived from other goals through planning, decision making, and problem solving functions.
function status assessments
Assessments of function status: actor performance (speed, accuracy), progress, liklihood that the goal will be achieved, etc.
manage individual agendas
Manage the agenda of each individual actor. Each actor manages his/her/its own agenda and these agendas may or may not be consistent.
mission goal
A goal is a desired system behavior and may involve attaining a desired state or maintaining a desired state. The mission goal is the high level goal to be accomplished in a commercial transport aircraft mission, that of safely, legally, and efficiently moving the aircraft and its cargo from the origin airport to the destination airport. In the course of flightdeck activities, the mission goal is decomposed into more specific subgoals.
share agenda information
Communicate information (overtly and covertly) about agendas among the actors. It is only through sharing agenda information that the individual agendas can approach consistency.
shared agenda information
Information about the actors' agendas shared between the actors. This may include queries, responses, commands, and information about goals, functions, priorities, and recognized discrepancies between different actors' agendas. It may also include negotiations on actor assignments and resource allocations.
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.
updated agendas
The agendas of the actors, updated by agenda management activities. Again, each actor maintains his/her/its own agenda, which may or may not be consistent with the agendas of other actors.
