ABSTRACT
In an earlier paper by the authors, an existing Air and Space Operations
Center (AOC) process model (i.e., Petri net) and new global and mission
models for the environment in which the AOC operates (i.e., System Dynamics)
were linked (federated). The focus of this paper is the development
of an operatorenvironment model (i.e., Agent-Based Model). An existing
systems framework for attention allocation of operators within the AOC
has been implemented in AnyLogic® software that supports multiple
modeling paradigms. Subject matter experts have helped define operator
interruptions (defined as shifts in activity), involving: 1) the agent's
past experience with the source (i.e., person) of the information; 2)
the information type (e.g., change priorities or distractions); 3) the
communication modality (e.g., Chat, Email, telephone, or in-person);
and 4) whether attention allocation attractors (e.g., information filters,
alerts, or summary displays) are present. The results for linking (federating)
the Petri net and System
Dynamics models are summarized, and new results for the Agent-Based
Model are presented based on a pilot-down scenario. It has been observed
that many AOC operators can become distracted by a pilotdown critical
event, even if the operator is not able to directly assist in the rescue.
Furthermore, this distraction has been hypothesized to have a detrimental
effect on the activities the non-involved operators are currently handling.
Linking the Agent-Based Model to the Petri net model is our next step
towards a multi-scale, hybrid model of the AOC.
