Hybrid Systems Dynamic, Petri Net, and Agent-Based Modeling of the Air and Space Operations Center
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 operator environment 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 agents 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 pilot down 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.
