Today, because the market is scattered around world, manufacturing activities are not limited to a single location and have spread globally. As result, discussion of scheduling factory has changed from classic network as need in real world. In this regard, study considers multiple factories by taking into account job transportation time between factories. The main problem here that each would b...

Nonlinear constrained programing problem (NCPP) has been arisen in diverse range of sciences such as portfolio, economic management etc.. In this paper, a multiobjective imperialist competitive evolutionary algorithm for solving NCPP is proposed. Firstly, we transform the NCPP into a biobjective optimization problem. Secondly, in order to improve the diversity of evolution country swarm, and he...

Nowadays, demand response programs (DRPs) play an important role in price reduction and reliability improvement. In this paper, an optimal integrated model for the emergency demand response program (EDRP) and dynamic economic emission dispatch (DEED) problem has been developed. Customer’s behavior is modeled based on the price elasticity matrix (PEM) by which the level of DRP is determined for ...

The protein folding problem is a fundamental problem in computational molecular biology and biochemical physics which led us to understand the function of a given sequence.The problem is NP-hard and the standard computational approach are not suitable to obtain the enough accurate structure in the huge conformation space. Simplied models such as hydrophobicpolar (HP) model have become one of th...

In this research work, first, based on the three-dimensional elasticity theory and by means of the Generalized Differential Quadrature Method (GDQM), free vibration characteristics of functionally graded (FG) rectangular plates resting on Pasternak foundation are focused. The two-constituent functionally graded plate consists of ceramic and metal grading through the thickness. A three-parameter...

In this paper, the investment portfolio is formed based on the data mining algorithm of CHAID on the basis of the risk status criteria. In the next step, the second investment portfolio is created based on the decision rules extracted by the DEA-BCC model. The final portfolio is created through a two-objective mathematical programming model based on the Imperialist Competitive algorithm.

The installation of a corona ring on an insulator string transmission line is one the solutions to reduce electric field stress surrounding energised end string. However, installing with optimum design magnitude challenging task. Therefore, in this work, method achieve for 132 kV composite non-ceramic was proposed using two optimisation methods: Imperialist Competitive Algorithm (ICA) and Grey ...
