Model Based Systems Engineering (MBSE) is seeing increased application in planning and design of NASA's missions. This suggests the question: what will be the corresponding practice of Model Based Mission Assurance (MBMA)? Contemporaneously, NASA's Office of Safety and Mission Assurance (OSMA) is evaluating a new objectives-based approach to standards to ensure that the Safety and Mission Assurance...
This paper presents a method for early software reliability assessment with planning and measurement of achieved reliability improvement during the development process of the software. Early assessment models for software (SW) reliability improvement contain parameters which are estimated using the existing records of reliability improvements, as related to the software size and applied SW development...
Using design models instead of executable code has shown itself to be an efficient way of increasing abstraction level of software development. However, applying established code-based software engineering methods to design models can be a challenge - due to different abstraction levels, the same metrics as for code are not applicable for the design models. One of practical challenges in using metrics...
With the increasing complexity in software and electronics in safety-critical systems new challenges to lower the costs and decrease time-to-market, while preserving high assurance have emerged. During the safety assessment process, the goal is to minimize the risk and particular, the impact of probable faults on system level safety. Every potential fault must be identified and analysed in order to...
Component-based software reliability analysis typically takes the reliability of component as an invariable property of component itself, disregards the fact that it changes when the component context it interacts changes due to a different operational profile of the system. This paper introduces a subdomain-based analysis approach to characterize the component into path-based architectural reliability...
The Department of Electronic Engineering of Beijing Institute of Technology is integrating emerging interconnect technologies with other high-performance technologies to meet the demanding requirement of future, real-time signal processing applications. For next-generation, scalable, modular and adaptable signal-processing system, a universal, flexible and high-performance signal processing module...
The ability to predict the reliability of a software system early in its development, e.g., during architectural design, can help to improve the system's quality in a cost-effective manner. Existing architecture-level reliability prediction approaches focus on system-level reliability and assume that the reliabilities of individual components are known. In general, this assumption is unreasonable,...
