A Latency-driven Availability Assessment for Multi-Tenant Service Chains [PDF]
Nowadays, most telecommunication services adhere to the Service Function Chain (SFC) paradigm, where network functions are implemented via software. In particular, container virtualization is becoming a popular approach to deploy network functions and to

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

Reliability Measurement for Multistate Manufacturing Systems with Failure Interaction [PDF]
Reliability is one of the important factors for manufacturing system. Most researches assume that the failure is independent and the components only have two states, which will lead to inaccurate results.

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

Dichotomies in Ontology-Mediated Querying with the Guarded Fragment [PDF]
We study the complexity of ontology-mediated querying when ontologies are formulated in the guarded fragment of first-order logic (GF). Our general aim is to classify the data complexity on the level of ontologies where query evaluation w.r.t.

Reliability Analysis of Common Cause Failure Multistate System Based on CUGF
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
