Closed-form expressions for distribution of sum of exponential random variables
In many systems which are composed of components with exponentially distributed lifetimes, the system failure time can be expressed as a sum of exponentially distributed random variables. A previousExpand

Software operational profile based test case allocation using fuzzy logic
We propose a generalized approach for the allocation of test cases, in which occurrence probability of operations obtained from FSOP are combined with the criticality of the operations using fuzzy inference system (FIS). Expand

Reliability evaluation of flow networks considering multistate modelling of network elements
Abstract This paper presents a simple method for evaluating the reliability of a multistate flow network. A system is considered reliable only if it successfully transmits at least the requiredExpand

Availability and mean life time prediction of multistage degraded system with partial repairs
Abstract In some environments, components might not always fail fully, but can degrade, and there can be multiple stages of degradation. In such cases, the efficiency of the system may decrease.Expand
