In this paper, we present a new method to determine the optimal location and parameter settings of UnifiedPower Flow Controller (UPFC) for removing voltage violations and transmission lines overloading. UPFC isconsidered as the most powerful member of the FACTS devices, that it can control shunt and series power flow.This option gives to UPFC the power to control the voltage profile and transmi...
Goal Programming Approach to the Bi-Objective Competitive Flow-Capturing Location-Allocation Problem
Majority of models in location literature are based on assumptions such as point demand, absence of competitors, as well as monopoly in location, products, and services. However in real-world applications, these assumptions are not well-matched with reality. In this study, a new mixed integer nonlinear programming model based on weighted goal programming approach is proposed to maximize the c...
Geological facies interpretation is essential for reservoir studying. The method of classification and identification seismic traces is a powerful approach for geological facies classification and distinction. Use of neural networks as classifiers is increasing in different sciences like seismic. They are computer efficient and ideal for patterns identification. They can simply learn new algori...
Small and medium-sized enterprises (SMEs) are a foundation for Economic and regional development that provide the background of the equipping resources and thereby increase national income and create job opportunities in the regional and national levels. Given the critical role of these firms, industrial planners should consider the competitive advantage of different industrial activities. In t...
In this paper, a leader–follower competitive facility location problem considering the reactions of the competitors is studied. A model for locating new facilities and determining levels of quality for the facilities of the leader firm is proposed. Moreover, changes in the location and quality of existing facilities in a competitive market where a competitor offers the same goods or services ar...
In recent years, the green supply chain has become a key strategy for the competitiveness of organizations, where the reverse and closed-loop supply chains are one way to achieve it. In the current competitive environment, the closed-loop supply chain helps reduce costs by re-using recyclables and reducing environmental pollution by reducing waste and extending product life. In this study, a cl...
We study the problem of exploring a simple grid polygon using a mobile robot. The robot starts from a location which is adjacent to the boundary of the polygon, and after exploring all the squares, has to return to its starting location. The robot is equipped with memory, but has no prior knowledge of the explored terrain. The view of the terrain is restricted to the four squares directly adjac...
This paper presents a Imperialist Competitive Algorithm (ICA) to seek the optimal number and location of FACTS devices in a power system. Unified Power Flow Controller (UPFC) has great flexibility that can control the active and reactive power flow and bus voltages, simultaneously. Decoupled model of the UPFC is applied to maximize the system loadability subject to the transmission line capacit...
مکان‌یابی با درنظرگرفتن موضوع رقابت در بازار، یک تصمیم راهبردی و بلندمدت محسوب می‌شود. چنانچه انتخاب مکان، بررسی‌های لازم صورت نگیرد، حیات سازمان تحت تأثیر قرار می‌گیرد. به‌دلیل وجود پیچیدگی‌های موجود مسائل مکان‌یابی، ارائه مدل‌های محدودیت‌های متنوعی مواجه است. هدف این پژوهش، توسعه مدل رقابتی درنظرگرفتن دو محصول از سوی سه رقیب است؛ برای منظور، مسئله به‌صورت بازی مکان ـ قیمت تعریف استفاد...
