An ePartner is a unit of the Mission Execution Crew Assistant (MECA) tool implementing a smart digital assistant. eParnters are, basically, event-driven agents that can behave autonomously to achieve the desired goals (deciding what to do basing on the current state) or providing a set of alternative ways to the human, allowing him/her to take the decisions. An ePartner provides system, environmental and human monitoring and diagnosis, coordination with other ePartners and high level decision support in cases of unforeseen conditions and events.
