The scenario tree based multistage stochastic programming model is popular to describe production planning problem. However, as its high-dimensional variables and large-scale solution space, the addressed model is hardly to be solved in an acceptable time. To deal with this challenge, we propose a variables clustering based differential evolution algorithm which combines two novel strategies i....

in this paper, an efficient and comprehensive hybrid intelligent technique for the optimal placement of phasor measurement units (pmus) is proposed to minimize the number of pmu installation subjected to full network observability. three main purposes of pmus output synchronous measurements are monitoring, control, and protection of power system. we have combined binary imperialistic competitio...

Multistage sampling of family data is a common design in the field of genetic epidemiology, but appropriate methodologies for analyzing data collected under this design are still lacking. We propose here a statistical approach based on the composite likelihood framework. The composite likelihood is a weighted product of individual likelihoods corresponding to the sampling strata, where the weig...

Quality is the hallmark of a competitive product. It is necessary to use inspection stations to check product quality and process performance. In this paper, we are concerned with the problem of location of inspection stations in a multistage manufacturing system. We present two stochastic search algorithms for solving this problem, one based on Simulated Annealing and the other on Genetic Algo...

there are many indices for measuring property rights (pr) security. they may be classified into two groups: subjective proxies and objective proxies. most of the proxies are subjective. one contribution of this paper is introducing a new approach for measuring government expenditures devoted to pr protection. calculating physical capital within the introduced new approach is another contributio...

Multistage interconnection networks (MINs) are popular in switching and communication applications and have been used in tele-communication and parallel computing systems for many years. Crosstalk a major problem introduced by an optical MIN, is caused by coupling two signals within a switching element. We focus on an efficient solution to avoiding crosstalk by routing traffic through an NϫN op...
