Abstract: In an embodiment, a method includes loading, from a first database, a representation of an Equipped-Human Reference Architecture (EHRA) model that is based on a human-equipment-task framework. The method further includes, based on indications of polymorphic attributes of at least one of a human, a task, an equipment, and an operational environment as defined by the EHRA model, selected by a user, loading a plurality of properties associated with the received indications from a second database. The method further includes polymorphically adding the plurality of properties to the representation of the EHRA model. The method further includes providing an equipped human system (EHS) solution architecture based on the EHRA model with the plurality of properties by analyzing one or more needs of the human, the task, the equipment, and the operational environment and determining an EHS solution meeting each need. The method further includes updating the EHRA model based on EHS solution architecture.
