Optimization of the Functional Structure of Airborne Hardware Complexes 000_12.pdf

The article shows that it is unnecessary to distribute functions on the basis of their belongings to one of the air vehicle (AV) level in order to take advantages of the integrated modular avionics (IMA) architecture in constructing the airborne hardware complexes (AHC). The method of construction and optimization of the functional structure of AV AHC on the basis of constructing a product functions tree is considered. The basic principles of constructing function groups optimized for implementation on a hardware platform with the desired characteristics are formulated. The authors developed a notion of indirect function realization and described its main advantages and disadvantages. Also, a product functions tree describing algorithm was proposed and outlined. The recursive action algorithm was given by the example of forming one group of functions. The method for improving the load on a hardware unit with its lack of load after the process of forming a group of functions was proposed.
