Plug and Play Weapons

In a perfect world…It should be possible to load any of these weapons…

…onto any of these airframes……and make available a set of common core capabilities…

…even if some weapon-specific capabilities are not available

K E N N E D Y C A R T E R6 Use of MDA and UML in Developing NATO Standards

Plug and Play Weapons

In the real world…Weapons have differing capabilities and different comms interactions…

…and each aircraft has a different execution environment…

Data Tables (Objects)

A primary goal was to avoid changing existing certified modules

When adding a new weapon to an existing aircraft 1. Capture weapon-specific behaviour in data if possible, but if not possible... 2. Capture weapon-specific behaviour in separate, small modules (domains)

The ALWI process can be summarised as…

Build and test a system model, using a precise modelling formalism

Populate the code generator with the system model and platform-specific configuration, and generate the target system

Summary

From the ALWI Final Report:“The proposed methodology for standardizing platform independent services is based on the Object Management Group (OMG) Model Driven Architecture™ (MDA®) initiative.The combination of MDA common services and common ICDs promises to offer ‘plug and play’ in the long term.”The ALWI xUML architecture and MDA process are to be used as the starting point for a new NATO Study (SG125) for Unmanned Airborne Vehicles…
