Modeling and Analysis of Software System Reliability
نویسندگان
چکیده
Software is an integral part of many products, ranging from durable goods such as household appliances to large and complex commercial and industrial systems. With the increasing dependency on software in our daily lives, the size and complexity of software systems has grown dramatically. This trend is of great interest to the software industry, calling for more practical analysis and prediction techniques of the reliability of software systems. Various modelling techniques for the analysis of software reliability at different development stages have appeared in the recent literature. This chapter describes the analysis of software failure data with commonly used non-homogeneous Poisson process (NHPP) models to track the reliability growth trend during the testing phase. This chapter deals with the use of available information from earlier releases of a project for early reliability prediction. A detailed case study is presented to illustrate the approach.

Reliability analysis of repairable systems using system dynamics modeling and simulation
Repairable standby system’s study and analysis is an important topic in reliability. Analytical techniques become very complicated and unrealistic especially for modern complex systems. There have been attempts in the literature to evolve more realistic techniques using simulation approach for reliability analysis of systems. This paper proposes a hybrid approach called as Markov system ...
متن کاملMathematical modeling and fuzzy availability analysis for serial processes in the crystallization system of a sugar plant
The binary states, i.e., success or failed state assumptions used in conventional reliability are inappropriate for reliability analysis of complex industrial systems due to lack of sufficient probabilistic information. For large complex systems, the uncertainty of each individual parameter enhances the uncertainty of the system reliability. In this paper, the concept of fuzzy reliability...

This paper deals with the Markov modeling and reliability analysis of urea synthesis system of a fertilizer plant. This system was modeled using Markov birth–death process with the assumption that the failure and repair rates of each subsystem follow exponential distribution. The first-order Chapman–Kolmogorov differential equations are developed with the use of mnemonic rule and these equation...

متن کاملA Bayesian Networks Approach to Reliability Analysis of a Launch Vehicle Liquid Propellant Engine
This paper presents an extension of Bayesian networks (BN) applied to reliability analysis of an open gas generator cycle Liquid propellant engine (OGLE) of launch vehicles. There are several methods for system reliability analysis such as RBD, FTA, FMEA, Markov Chains, and etc. But for complex systems such as LV, they are not all efficiently applicable due to failure dependencies between compo...
متن کاملReliability analysis of a robotic system using hybridized technique
In this manuscript, the reliability of a robotic system has been analyzed using the available data (containing vagueness, uncertainty, etc). Quantification of involved uncertainties is done through data fuzzification using triangular fuzzy numbers with known spreads as suggested by system experts. With fuzzified data, if the existing fuzzy lambda–tau (FLT) technique is employed, then the comput...
