This paper studies maintained systems with nonself-announcing (" hidden") failures that
deteriorate due to both shocks and graceful degradation. Shocks occur according to a …

The recent literature showed that, in many cases, ordered binary decision diagram (OBDD)-
based algorithms are more efficient in reliability evaluation compared to other methods such …

The renewal model for cost-benefit optimization including maintenance is presented. Three
types of maintenance strategies are proposed, ie age-dependent maintenance, block …

Risk Assessment is a fundamental support for decisions related with design, construction,
operation and maintenance of industrial products, systems and infrastructures. Risks are …

The integral equation of renewal type has many applications in applied probability.
However, it is rarely solvable in closed form. In this paper, we describe a numerical method …

Weibull renewal function has attracted a lot of attention because the Weibull distribution
describes in a relatively simple analytical manner a wide range of realistic behavior and its …

The theory for setting up suitable objective functions is extended to existing structures which
can have a different distribution of the time to first failure than all other failure time …

The renewal and renewal‐intensity functions with minimal repair are explored for the
Normal, Gamma, Uniform, and Weibull underlying lifetime distributions. The Normal …

The renewal function (RF) has many applications such as reliability analysis, maintenance
policy optimization and inventory planning. The RFs of most distribution functions do not …

The renewal functions (RFs) of most distribution functions do not have closed-form
expressions while such expressions are desired for the optimization problems involved RF …
