Network Centric Product Support

Network Centric Product Support (NCPS) is an early application of an Internet of Things (IoT) computer architecture developed to leverage new information technologies and global networks to assist in managing maintenance, support and supply chain of complex products made up of one or more complex systems, such as in a mobile aircraft fleet or fixed location assets such as in building systems. This is accomplished by establishing digital threads connecting the physical deployed subsystem with its design Digital Twins virtual model by embedding intelligence through networked micro-web servers that also function as a computer workstation within each subsystem component (i.e. Engine control unit on an aircraft) or other controller and enabling 2-way communications using existing Internet technologies and communications networks - thus allowing for the extension of a product lifecycle management (PLM) system into a mobile, deployed product at the subsystem level in real time. NCPS can be considered to be the support flip side of Network-centric warfare, as this approach goes beyond traditional logistics and aftermarket support functions by taking a complex adaptive system management approach and integrating field maintenance and logistics in a unified factory and field environment. Its evolution began out of insights gained by CDR Dave Loda (USNR) from Network Centric Warfare-based fleet battle experimentation at the US Naval Warfare Development Command (NWDC) in the late 1990s, who later lead commercial research efforts of NCPS in aviation at United Technologies Corporation. Interaction with the MIT Auto-ID Labs, EPCglobal, the Air Transport Association of America ATA Spec 100/iSpec 2200 and other consortium pioneering the emerging machine to machine Internet of Things (IoT) architecture contributed to the evolution of NCPS.

Simply put, this architecture extends the existing World Wide Web infrastructure of networked web servers down into the product at its subsystem's controller level using a Systems Engineering "system of systems" nested approach. Its core is an embedded dual function webserver/computer workstation connected to the product controller's test ports (as used in retrofit applications, or integrated directly into the controller for new products), hence providing access to operational cycles, sensor and other information in a clustered, internet addressable node that allows for local or remote access, and the ability to host remotely reconfigurable software that can collect and process data from its mated subsystem controller onboard and pull in other computing resources throughout the network. It can then establish a localized wireless World Wide Web in and around the product that can be securely connected to by a mechanic with any web browser-equipped handheld independent of the greater World Wide Web, as well as seamlessly integrate into global networks when external wireless communications is available - thus creating data Digital Twins at the factory, connecting deployed product usage in the Product lifecycle with constantly updated digital threads. This allows for an integrated approach which enables both offline and online updates to occur. Legacy systems usually require a human to physically connect a laptop to the system controller or a telematic solution to manually collect data and carry it back to a location where it can be later transferred to the factory or to restricted webserver-based download sites for offboard analysis.
