The reliability assessment of distribution networks is one of the most important issues which the designers are challenging. In this paper, reliability assessment of a distribution network that include distributed generation is studied using Monte Carlo method. There are photovoltaics (PVs), wind turbines (WTs) and gas reciprocating engine (GREs) in this distributed generation. Normal and Weibu...

This study gives the reliability analysis of bearing capacity of large-diameter piles under osterberg test. The limit state equation of dimensionless random variables is utilized in the reliability analysis of vertical bearing capacity of large-diameter piles based on Osterberg loading tests. And the reliability index and the resistance partial coefficient under the current specifications are c...

The aim of this paper is to propose Particles Swarm Optimization (PSO) to calculate the reliability index of a given structure. First of all, the basic modeling of time independent structure reliability is presented, and is followed by the optimization prob lem formulation to assess reliability index with PS O to overcome the difficulties of classical method to do a global search. Two applicati...

It is essential to consider the acceptable threshold in the assessment of a hydrological model because of the scarcity of research in the hydrology community and errors do not necessarily cause risk. Two forecast errors, including rainfall forecast error and peak flood forecast error, have been studied based on the reliability theory. The first order second moment (FOSM) and bound methods are u...

A complex structure has many uncertain factors and how to make a more accurate analysis on the structure reliability by a method is the key in engineering calculation. Rough set theory is utilized to analyze the fuzzy, random and uncertain factors and upper and lower approximation set relation is used to calculate the value taking interval of reliability index to make reliability index analysis...

The 15D is a generic, 15-dimensional, standardised, self-administered measure of health-related quality of life (HRQOL), that can be used as a profile and single index score measure. This paper introduces alternative valuation models based on the multi-attribute utility theory for generating the single index scores, and examines their feasibility, reliability and validity by using several data ...
