Approaches to Performance Evaluation of Airborne Mission Systems in the Acquisition Process
(0) Adding new functionality in a mission system as a result of upgrades or extending existing capability during spiral development has been known to cause software performance problems. Resource utilisation increases and integration becomes more complex. Problems such as processing capacity, buffer capacity or potential bottlenecks may affect mission system performance, operational usage or maintenance effort of the aircraft. The core problem is how to evaluate the performance characteristics of the software in the mission system within the limits of the information made available during acquisition. During acquisition we typically do not have access to source code, hardware and development environments. Based on a stream of reports with various levels of detail, we need to assess the status and the risks as well as investigate potential options for improvement. A number of approaches and models for performance evaluation in such circumstances have been investigated.This paper reviews various approaches and tools for performance evaluation of airborne mission system software, such as scenario-based, simulation and benchmarking. An example of the simulation approach is the “performance calculator – a discrete events model based on the Worst Case Execution Times of the applications as a characteristic of their behaviour. The model can be used for a quick evaluation of the available processing capacity and schedulability when the mission system is modified.
