A Reliability Model of integrated modular avionics (IMA) Software Considering with environment

Abstract

Considering of the actual runtime environment, this paper presents a software reliability model based on Itô stochastic differential equation (SDE). We first summarize runtime environmental factors and build a reliability model considering with some of these factors. Then, based on the simulation data of IMA platform runtime environment, we build several measures to evaluate software reliability and analyze sensitivity of parameters in the model. This paper is a preliminary exploration of the software reliability in actual Runtime Environment. Although there are some deficiencies, it lays a foundation for further research.
