Providing command and control agility: A software product line approach

Command and Control (C2) is a broad concept that encompasses the coordination of individuals and organizations towards achieving a goal. However, dynamic and uncertain scenarios, such as military and disaster relief operations, present an inherent challenge to C2 activities. In such situations, plans often need to be changed in the face of unforeseen problems, and even coordination processes may be subject to variation. This dynamism increases the complexity of resource management and requires C2 Agility-i.e., the ability to respond to change in a timely and suitable fashion. Nonetheless, there is a lack of solutions to provide C2 Agility to cope with dynamic contexts. To address this problem, this work proposes a computational model of C2 Agility for a team of autonomous agents. This model describes how to combine reconfiguration of individual team members and of coordination approaches to adapt to context changes. The proposed approach leverages a typed-parameterized extension of a channel system to define the coordinating roles and responsibilities of team members. Each member is modeled as a dynamic software product line, with the inherent ability to reconfigure itself. To assess this model, a team of Unmanned Aerial Vehicles (UAV) performing a reconnaissance mission was simulated. The simulation showed that the proposed model was suitable for dealing with dynamic contexts. Particularly, metrics for the agile approach suggest improved system resilience in the face of induced perturbations, compared to non-agile C2. The obtained results with the proposed software-based simulations showed that the proposed model is useful in providing C2 Agility to the studied scenarios, making the behavior of the entities specified in the model capable of dealing with context changes.

Automated summary

Command and Control (C2) is a broad concept that requires agility to respond to dynamic and uncertain scenarios. This study proposes a computational model of C2 Agility that combines individual reconfiguration and coordination approaches to adapt to context changes. Simulations using a team of UAVs showed that the proposed model improved system resilience and enabled effective response to induced perturbations.
