Transmission expansion planning (TEP), the determination of new transmission lines to be added an existing power network, is a key element in system planning. Using classical optimization define most suitable reinforcements desirable alternative. However, extent under-study problems growing, because uncertainties introduced by renewable generation or electric vehicles (EVs) and larger sizes und...

The human has always been to find the best in all things. This Perfectionism has led to the creation of optimization methods. The goal of optimization is to determine the variables and find the best acceptable answer Due to the limitations of the problem, So that the objective function is minimum or maximum. One of the ways inaccurate optimization is meta-heuristics so that Inspired by nature, ...

The research suggests that Chinese companies do not subscribe to ‘western’ strategy theory. As they rapidly internationalise through massive Foreign Direct Investment, Chinese companies are developing new perspectives on achieving competitiveness. A comparison of the Resource-Based View of strategy (RBV) constructs from western literature with identified (indigent) Chinese business strategies f...

It is shown that the work function algorithm for the 2-evader problem has competitive ratio m ? 2 for all metric spaces with m points. This settles the k-server conjecture for metric spaces with k+2 points.

periodic vehicle routing problem focuses on establishing a plan of visits to clients over a given time horizon so as to satisfy some service level while optimizing the routes used in each time period. this paper presents a new effective heuristic algorithm based on data mining tools for periodic vehicle routing problem (pvrp). the related results of proposed algorithm are compared with the resu...

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.

in today's design, system complexity and increasing demand for safer, more efficient and less costly systems have created new challenges in science and engineering. locomotives are products which are designed according to market order and technical needs of customers. accordingly, targets of companies, especially designers and manufacturers of locomotives, have always been on the path of progre...
