Mrityunjay Brahma. "An Approach to Build Software Based on Fault Tolerance Computing Using Uncertainty Factor". International Journal of Engineering Trends and Technology (IJETT). V6(6):302-306 Dec 2013. ISSN:2231-5381. www.ijettjournal.org. published by seventh sense research group
In this work, we have started with an overview on fault tolerance based system. In case of design diversity based software fault tolerance system, we observed that uncertainty remains an important factor. Keeping this factor, we have discussed about implementing Bayes’ theorem and probabilistic mathematical model to handle the uncertainty factor. We assume that, once developed, the complete model will give us better efficiency. The rest of this paper deals with other types of fault tolerance systems and their approaches. This part is a kind of literature review, which includes, fault tolerant computing schemes that rely on the single-design as well as on the multiple-design. Further, in single-design, we have discussed about recovery block, N-version programming, N self-checking programming scheme. Lastly, focusing on multiple-design, we have discussed about software engineering aspects, error detection mechanisms and fault tolerance by fault injection. The paper ends with a general conclusion.
