This paper investigates a scheduling combined manpower-vehicle routing problem with a central depot in and a set of multi-skilled manpower for serving to customers. Teams are in different range of competencies that it will affect the service time duration. Vehicles are in different moving speeds and costs and not all the vehicles are capable to move toward all the customers' sites. The objective is to minimize the total cost of servicing, routing, and lateness penalties. This paper presents a mixed integer programming model and two meta-heuristic approaches of genetic algorithm (GA) and artificial bee colony algorithm (ABC) are developed to solve the generated problems. Furthermore, Taguchi experimental design method is applied to set the proper values of parameters. The available results show the higher performance of proposed GA compared with ABC, in quality of solutions.

artificialbeecolony (ABC) algorithm, a popular swarm intelligence technique based on the intelligent foraging behavior of honey bees, is good at exploration but poor at exploitation. Grenade Explosion Method (GEM) which mimics the mechanism of a grenade explosion has high reliability and fast convergence. Two modified versions of ABC inspired by GEM, namely GABC1 and GABC2, are first proposed to enhance the classical ABC's exploitation ability. GEM is embedded in the employed bees' phase of GABC1, whereas it is embedded in the onlooker bees' phase of GABC2. The performance differences between GABC1 and GABC2 were assessed on two sets of well-known benchmark functions and compared with that of the classical ABC and several other improved ABC algorithms. The experiments show that GABC1 has similar or better performance than GABC2 in most cases, but GABC2 performs more robust and effective than GABC1 on all the functions, they significantly outperform the competitors. These results suggest that the proposed algorithms can effectively serve as alternatives for solving global optimization problems. (C) 2014 Elsevier B.V. All rights reserved.

Optimization of real estate portfolio is to select two or more different types of real estate for investment, and the previous models based on expected return-variance cannot meet the needs of the investors. Furthermore, the investors change their risk preference with the risk level. In this study, firstly, the semi-variance model of real estate investment portfolio based on risk preference coefficient was constructed. The return per unit of risk is the key factor to determine an investment decision. Secondly, artificial bee colony algorithm (ABC) was employed to solve the constructed model. Finally, a real-world case was analyzed to verify the performance of ABC. The result indicated that ABC could generate better solution than GA and it could be regarded as a useful approach for solving real estate portfolio problem.

This paper proposes a vector quantization (VQ) codebook generation method for image data compression using a combined scheme of Hotelling transform (HT), the artificialbeecolony (ABC) algorithm and the Linde-Buzo-Gray (LBG) algorithm. First, the grayscale image is divided into a set of non-overlapping image blocks. Each block is represented by an input vector, and these input vectors are then sorted by Hotelling transform. Second, the ABC algorithm is employed to select some of the sorted vectors to form an initial codebook. Third, this codebook serves as the input of the LBG algorithm to compute vector quantization codebook. The experimental results show that the proposed HT-ABC-LBG algorithm outperforms the FF-LBG algorithm in terms of the quality of the decompressed image and the computation time.

This paper proposes an innovative method for identifying the locations of multiple simultaneous acoustic emission (AE) events in plate-like structures from the view of image processing. By using a linear lead zirconium titanate (PZT) sensor array to record the AE wave signals, a reverse-time frequency-wavenumber (f-k) migration is employed to produce images displaying the locations of AE sources by back-propagating the AE waves. Lamb wave theory is included in the f-k migration to consider the dispersive property of the AE waves. Since the exact occurrence time of the AE events is usually unknown when recording the AE wave signals, a heuristic artificialbeecolony (ABC) algorithm combined with an optimal criterion using minimum Shannon entropy is used to find the image with the identified AE source locations and occurrence time that mostly approximate the actual ones. Experimental studies on an aluminum plate with AE events simulated by PZT actuators are performed to validate the applicability and effectiveness of the proposed optimal image-based AE source identification method.

The vector quantization was a powerful technique in image compression. The widely used method such as the Linde-Buzo-Gray (LBG) algorithm always generated local optimal codebook. Recently, particle swarm optimization was adapted to obtain the near-global optimal codebook of vector quantization. The alterative method called the quantum particle swarm optimization was developed to improve the results of original PSO algorithm. The honey bee mating optimization was used to develop the algorithm for vector quantization. In this paper, we proposed a new method based on the artificialbeecolony (ABC) algorithm to construct the codebook of vector quantization. The proposed method uses LBG method as the initial of ABC algorithm to develop the VQ algorithm. This method is called ABCLBG algorithm. The ABC-LBG algorithm is compared with four algorithms described above. Experimental results showed that the ABC-LBG algorithm is more reliable and the reconstructed images get higher quality compared to other methods.

In this study, 4E analysis tor feasible integrated systems for cogeneration of fresh water was investigated. Steam generation provided by a steam boiler, designed to supply the thermal heat requirements of MED-TVC and *** systems. Parametric analysis is made to determine CO2 emission rate, gain output ratio, exergy destruction rate and special heat rate for each system. By using artificial bee colony algorithm, systems were optimised for maximum exergy efficiency and minimum cost of the produced distilled water. The results showed that by selecting final optimum solutions, the distillated water cost reduced by 18.1% and 28.8% for MED-TVC and MED-TVC .FH systems respectively. Also exergy efficiency increased from 3.2% and 4.04% in the base case to 3.63% and 4.47% for MED-TVC and *** respectively in the optimum case. The system with feed water preheater, has more exergy efficiency and less CO2 emission, also the cost of distilled water reduced by 7. 86.%
