this article proposes composition of fuzzy sets theory with discrete-event simulation and puts it into application in order to model uncertain activity duration in simulating a real-world system. the purpose of this paper is to assess the usefulness of fuzzy simulation for modeling uncertain activity duration, especially when insufficient or no sample data is available. in this research, fuzzy ...

under the smart grid environments, demand response resources (drrs) as power system resources can effectively participate in and improve performance of electric systems. congestion management is one of the technical challenges in which drrs can play a significant role. previously, congestion management is applied without considering the power system uncertainties. therefore, a stochastic conges...

Probabilistic frequent itemset mining, which discovers frequent itemsets from uncertain data, has attracted much attention due to inherent uncertainty in the real world. Many algorithms have been proposed to tackle this problem, but their performance is not satisfactory because handling uncertainty incurs high processing cost. To accelerate such computation, we utilize GPUs (Graphics Processing...

There has been an increased growth in a number of applications that naturally generate large volumes of uncertain data. By the advent of such applications, the support of advanced analysis queries such as the skyline and its variant operators for big uncertain data has become important. In this paper, we propose the effective parallel algorithms using MapReduce to process the probabilistic skyl...

This paper investigates the statistical properties of voltage unbalance factor in a three-phase system due to an asymmetrical load with uncertain parameters. The parameters are treated as random variables Gaussian distribution. Random asymmetry results values factor. probability density function, cumulative distribution mean value and variance derived closed form numerically validated. obtained...

Demand response programmes reduce peak-load consumption and could increase off-peak demand as a load-shifting effect often exists. In this research we use three-stage game to assess the effectiveness of dynamic pricing regarding its economic consequences. We consider retailer's strategic supplies on forward or real time markets, when is uncertain with consumer disutility incurred from load-shed...

BACKGROUND Patterns of influenza molecular viral shedding following influenza infection have been well established; predictors of viral shedding however remain uncertain. OBJECTIVES We sought to determine factors associated with peak molecular viral load, duration of shedding, and viral area under the curve (AUC) in children and adult Hutterite colony members with laboratory-confirmed influen...

This paper presents the study of overload contingency in the distribution system using fuzzy multiobjective approach considering customer load pattern. A model of 25 bus distribution system having five feeders, 20 loads and 29 distribution lines is simulated using Mi-Power software. Customer load pattern of the distribution system is designed using MATLAB. Taking the advantage of handling uncer...
