Real fire simulation training systems have gradually become an important method of emergency rescue team and improvement. However, the failure rate such is high, which threatens safety trainers. Therefore, this study takes a real scenario as research object analyzes system structure base. The base analyzed divided into three systems: smoke heat room, combustion water, oil, gas supply. Then, rel...

Uncertainties in structural parameters and in the excitation, and consequently in the response, obviously affect the structural reliability considerably. In this work, recent developments in the reliability analysis for the treatment of uncertain linear structures subjected to dynamic loading are presented. Although any reliability problem could be solved in principle by Direct Monte Carlo simu...

This paper investigates the suitability of Latin Hypercube sampling (LHS) for composite electric power system reliability analysis. Each sample generated in LHS is mapped into an equivalent system state and used for evaluating the annualized system and load point indices. DC loadflow based state evaluation model is solved for each sampled contingency state. The indices evaluated are loss of loa...

One of the most important problems discussed recently in structural engineering is the structural reliability analysis considering uncertainties. To have an efficient optimization process for designing a safe structure, firstly it is required to study the effects of uncertainties on the seismic performance of structure and then incorporate these effects on the optimization process. In this stud...

Integrated Deterministic and Probabilistic Dependability Analysis (IDPDA) is respectively required for safety properties verification and reliability & availability assessment of critical systems. This paper presents an approach towards IDPDA using Coloured Petri Nets (CPN). Contributions are related to: (a) hierarchical modelling guidelines that cover deterministic and probabilistic features o...

BACKGROUND Questionnaires are used extensively in medical and health care research and depend on validity and reliability. However, participants may differ in interest and awareness throughout long questionnaires, which can affect reliability of their answers. A method is proposed for "screening" of systematic change in random error, which could assess changed reliability of answers. METHODS ...
