The invention provides an
integrated modular avionics system service capability assessment method which includes the steps of identifying and classifying resources provided by an IMA (
Integrated Modular Avionics) platform, performing independence identification and quantification on resources of the IMA (
Integrated Modular Avionics) platform, setting up an IMA (
Integrated Modular Avionics) platform resource matrix, obtaining the maximum service capability of the IMA (Integrated Modular
Avionics) platform from the IMA (Integrated Modular
Avionics) platform matrix, determining whether an IMA (Integrated Modular
Avionics)
system satisfies the service capability demands of
avionics system functions, resetting elements in a corresponding resource matrix to zero when resource failure occurs or reducing values according to the degradation of resources, repeating the determination process, and assessing the service capabilities of the IMA (Integrated Modular Avionics) platform after resource failure. The integrated modular avionic
system service capability assessment method is capable of assessing the service capabilities of the IMA (Integrated Modular Avionics) platform with resource sharing characteristics by quantifying the service capabilities of the system, thereby helping to maximize the
resource utilization of the system. Furthermore, the integrated modular avionic
system service capability assessment method helps system integrators reasonably plan the variety and quantity of
residence functions of the IMA (Integrated Modular Avionics) platform, thereby enhancing the 'failure-safety' capability of the
avionics system.
