Short-Term Reliability Assessment of Generating Systems Considering Demand Response Reliability

IEEE Access, 2020
Demand response (DR), one kind of flexible resources, can decrease the operating costs of power systems and improve their reliability. However, DR is not absolutely reliable due to its inherent uncertainty, so its function of improving system reliability

Performability Assessment of Containerized Multi-Tenant IMS through Multidimensional UGF

, 2022
We advance a performability assessment of a multi- tenant containerized IP Multimedia Subsystem (cIMS), i.e.: one and the same infrastructure is shared among different providers (or tenants).

Efficient harmony search optimization for preventive-maintenance-planning for nuclear power systems

International Journal for Simulation and Multidisciplinary Design Optimization, 2014
This paper combines the universal generating function UGF with harmony search (HSO) meta-heuristic optimization method to solve a preventive maintenance (PM) problem for series-parallel system. In this work, we consider the situation where system and its

Preventive Maintenance Interval Optimization for Continuous Multistate Systems

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Preventive maintenance (PM), which is performed periodically on the system to lessen its failing probability, can effectively decrease the loss caused by the system breakdown or the performance degradation. The optimal PM interval has been well studied for both binary‐state systems (BSSs) and discrete multistate systems (MSSs). However, in reality, the

Reliability Analysis of Common Cause Failure Multistate System Based on CUGF

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
This paper addresses the problem of mixed uncertainty in the reliability analysis of multistate systems under common cause failure conditions. Combining the cloud model theory, universal generation function (UGF) method, and common cause failure theory, the universal generation function method is extended based on a probabilistic cloud model, i.e., the

Hybrid Universal Generating Function for the Reliability Assessment of Multi-State Systems under Aleatory and Epistemic Uncertainties

, 2013
International audienceIn this work, we extend the traditional universal generating function (UGF) approach for multi-state system (MSS) reliability assessment to account for both aleatory and epistemic uncertainties.

Reliability Analysis of k‐out‐of‐n Systems of Components with Potentially Brittle Behavior by Universal Generating Function and Linear Programming

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Due to initial cracks, careless construction, and extreme load conditions, components with brittle behavior may exist in a structural system. The presence of brittle behavior of components usually is accompanied by a low strength. However, existing methods for calculating the reliability of structures of components with brittle behavior are rather ...

Reliability and sensitivity analysis of consecutive k-out-of-r-from-n:F systems using trapezoidal neutrosophic numbers and UGF approach [PDF]

Neutrosophic Sets and Systems
Reliability analysis under uncertain, imprecise, and time-dependent conditions remains a critical challenge in system engineering, especially for complex configurations such as linear consecutive (LC) k-out of-r-from-n:F systems.
