This paper addresses the usefulness of Artificial Bee Colony (ABC) optimizationalgorithm for assessment of distribution system reliability. The penalty cost functions are formulated which is related to the failure rate and repair time of each distribution segment. And also, satisfy the reliability constraint such as SAIFI, SAIDI, CAIDI and AENS. The finest values of failure rate and repair time cost function are evaluated using ABC algorithm for reliability enhancement. The performance comparison between ABC and particleswarmoptimization (PSO) algorithm also has been done in this paper. In addition, for showing the effectiveness of proposed methodology the numerical results have been compared to the different intelligent techniques that are available in the published literature.

This paper mainly research on the container tuck route optimization problem with the integrated loading and unloading operation. Considered the disperse-stacking of containers in yards and the loading/unloading operations of each berth, the objective function of scheduling problem is the optimal rout of the container truck. In order to solve this problem, the hybrid swarm intelligence algorithm (PSO-ACO) is proposed, which combined the particle swarm optimization algorithm with the ant colony optimizationalgorithm. The hybrid swarm intelligence algorithm takes advantage of strong local search ability of ant colony optimizationalgorithm and the ACO's pheromone taxis, which can avoid the particle swarm optimization algorithm fall in the local optimum during the convergence. The results show that the mathematical model and hybrid algorithm have effective, reliability and stability in solving the container truck scheduling problem.

An effective fusion method for combining information from single modality system requires Multimodal biometric crypto system. Fuzzy vault has been widely used for providing security, but the disadvantage is that the biometric data are easily visible and chaff points generated randomly can be easily found, so that there is a chance for the data to be hacked by the attackers. In order to improve the security by hiding the secret key within the biometric data, a new chaff point based fuzzy vault is proposed. For the generation of the secret key in the fuzzy vault, grouped feature vectors are generated by combining the extracted shape and texture feature vectors with the new chaff point feature vectors. With the help of the locations of the extracted feature vector points, x and y co-ordinate chaff matrixes are generated. New chaff points can be made, by picking best locations from the feature vectors. The optimal locations are found out by using particleswarmoptimization (PSO) algorithm. In PSO, extracted feature locations are considered particles and from these locations, best location for generating the chaff feature point is selected based on the fitness value. The experimentation of the proposed work is done on Yale face and IIT Delhi ear databases and its performance are evaluated using the measures such as Jaccard coefficient (JC), Genuine Acceptance Rate (GAR), False Matching Rate (FMR), Dice Coefficient (DC) and False Non Matching Rate (FNMR). The results of the implementation give better recognition of person by facilitating 90% recognition result. (C) 2015 Production and hosting by Elsevier B.V. on behalf of King Saud University.

Economy, reliability and environmental friendly are primary goals when modeling modern unit commitment problems. In this study, we establish a multi-objective unit commitment model considering the above objectives. In particular, the pricing support for ultra-low emissions is addressed together with startup/shutdown, generation and environment concerns when calculating the operation cost of thermal units, which conforms the present situation of power markets, especially in China. To solve the complicated nonlinear model, a multi-objective particle swarm optimization algorithm is developed. Finally, a series of experiments were performed on a modified 26-thermal-unit test system, which demonstrates the superiority of this research.

One of the most classic algorithms for association rules mining is the Apriori algorithm. But it can't satisfy the requirement as the increasing scale of the data. It has some disadvantages such as scanning database too many times, setting support and confidence thresholds artificially. particleswarmoptimization is one of the classic heuristic algorithms and some researchers has used it to association rules mining. But the problem that it may fall into the local optimal solution prematurely affects the efficiency of the algorithm. A new improved particle swarm optimization algorithm is proposed to solve this problem by controlling the particle velocity. In order to improve the efficiency and reliability of the algorithm in the condition of guarantee the global searching capability, an adaptive acceleration coefficient control method based on distance is used.

In recent years, with the high frequency of the infectious diseases outbreak, the prediction of the infectious diseases has become more and more important, so effective prediction of the infectious diseases can safeguard social stability and promote national economic prosperity. In order to improve the predictive accuracy of infectious diseases, the weight and threshold of BP neural network was optimized by using the improved genetic algorithm based on the PSO (particle swarm optimization algorithm) while the error function is the mean square error, the mean absolute error and the mean absolute percentage error. The simulation experimental results show that the optimized BP neural network can effectively reduce the mean square error, the mean absolute error and the mean absolute percentage error, and improve the prediction accuracy.

The gray Verhulst model has the extremely widespread application in the study of minority, poor information and uncertainty question when the data show saturated state or s-shaped sequences. However the gray Verhulst model built by weakening the randomness of data sequence, lacking of self-organizing and self-learning. Some scholars study on this issue, and put forward a kind of gray Verhulst-BPNN combination forecast model. In this model, Partial-data set is used to establish Verhulst model group and BP neural network is utilized to build up the nonlinear mapping between partial-data Verhulst model group and original data in order to overcome the defects of the neural networking training with small sample of time series data. However, gray Verhulst-BPNN combination forecast model still has the problems of the local minimum and slow convergence caused by adjusting the network connection weights with error back propagation. Considering the PSO algorithm has the advantages of high accuracy and fast convergence, this paper put forward a kind of PSO-based combined forecasting gray Verhulst-BPNN model. Experiments show that the combined model has higher prediction precision and good stability.

Using particleswarmoptimization to handle complex functions with high-dimension it has the problems of low convergence speed and sensitivity to local convergence. The convergence of particleswarmalgorithm is studied, and the condition for the convergence of particleswarmalgorithm is given. Results of numerical tests show the efficiency of the results. Base on the idea of specialization and cooperation of particle swarm optimization algorithm, a multiplicate particle swarm optimization algorithm is proposed. In the new algorithm, particles use five different hybrid flight rules in accordance with section probability. This algorithm can draw on each other ' s merits and raise the level together The method uses not only local information but also global information and combines the local search with the global search to improve its convergence. The efficiency of the new algorithm is verified by the simulation results of five classical test functions and the comparison with other algorithms. The optimal section probability can get through sufficient experiments, which are done on the different section probability in the algorithms.

This paper investigates a novel inventory and distribution planning model with non-conforming items disposal (NIDPNCID) under fuzzy random environment to minimize the whole process cost. In this process, a certain fraction or a random number of produced items are defective. These non-conforming items are rejected in order to improve the consumer satisfaction. To solve the problem, a dynamic programming-based particleswarmoptimization (DP-based PSO) algorithm with fuzzy random simulation is proposed, which can be easy to implement. In more specific terms, DP-based PSO can reduce the dimensions of a particle by using the state equation, which significantly reduced the solution space.

Performing microarray expression data classification can improve the accuracy of a cancer diagnosis. The varying technique including Support Vector Machines (SVMs), Neuro-Fuzzy models (NF), K-Nearest Neighbor (KNN), Neural Network (NN), and etc. have been applied to analyze microarray expression data. In this investigation, a novel complex network classifier is proposed to do such thing. To build the complex network classifier, we tried a hybrid method based on the particle swarm optimization algorithm (PSO) and Genetic Programming (GP), of which GP aims at finding an optimal structure and PSO accomplishes the fine tuning of the parameters encoded in the proposed classifier. The experimental results conducted on Leukemia and Colon data sets are comparable to the state-of-the-art outcomes.
