Abstract

Software reliability estimation for systems operating in the field has been extensively discussed in the literature and several models have been developed. However, this approach of reliability estimation is a reactive approach, where the product has been deployed in the field and field returns are monitored for software issues. An area where there has been limited focus is on the evaluation of software reliability during the development phases of the software. The objective of this paper is to develop and present a methodology for embedded software reliability estimation before it has been deployed in the field. This approach involves assessing reliability risk at the requirements phase, and a method for mitigating and quantifying mitigation amount for reliability estimation through model-in-loop, processor-in-loop, and hardware-in-loop tests. This is a software reliability estimation through proactive risk mitigation strategies and enable guidelines for organizations on the software reliability at product launch.

新产品开发中的嵌入式系统软件可靠性评估

在文献中对现场运行的系统的软件可靠性评估进行了广泛的讨论，并开发了几种模型。然而，这种可靠性评估方法是一种被动的方法，在这种方法中，产品已经部署在现场，并且现场返回是为了监测软件问题。在软件开发阶段对软件可靠性的评估受到了有限的关注。本文的目的是开发并提出一种方法，在嵌入式软件被部署到现场之前进行可靠性评估。该方法包括在需求阶段评估可靠性风险，以及通过模型在环、处理器在环和硬件在环测试来减轻和量化可靠性评估的减轻量的方法。这是通过前瞻性风险缓解策略进行的软件可靠性评估，并在产品发布时为组织提供有关软件可靠性的指导方针。
