Artykuł prezentuje problematykę optymalizacji i niezawodności sterowania ruchem pojazdów w obrębie skrzyżowań z zastosowaniem metod klasycznych i algorytmów genetycznych z rozmytą oceną wartości chromosomu. Są to rozwiązania alternatywne do aktualnie wykorzystywanych w systemach logistyki miejskiej. Autorzy wykonując badania wskazali, że operatory genetyczne pozwalają o około 43% sprawniej sterować...
Gear reducer is one of the most widely used methods in mechanical transmission, optimization of which is of great significance in improving the bearing capacity, prolonging service life and reducing its size and quality. By Visual Basic programming mixed with MATLAB, automatic optimization design for gear reducer is realized in the paper, design efficiency and quality greatly improved. Genetic algorithm...
This paper discusses an energy constrained distributed estimation in wireless sensor network (WSN) based on frequency and time division multiple access (FTDMA). In a measurement with WSN, sensors transmit observed quantized data to a fusion center (FC) via radio communication channels, to obtain a final estimate. Such systems require a multiple access technique such as time division multiple access,...
Fault detection and diagnosis can effect system reliability and avoid expensive maintenance. In a manufacturing process, a simple fault can lead to environmental damage. In this way, one of the most commonly applied fault detection method is the parameter estimation technique. In this paper, we present an advanced algorithm for the estimation of electrical machine parameters by combining two approaches:...
This paper proposes a new method for the incorporation of the generation unit and transmission line unavailability in the solution of the unit commitment problem. The above parameters are taken into account in order to assess the required spinning reserve capacity at each hour of the dispatch period, so as to maintain an acceptable reliability level. The unit commitment problem is solved by a Genetic...
Due to the importance of power/ground network, lots of researches have been made on it. But they only focused on the minimal area of it. By discussion on the relation among Vdd, performance and power consumption, this paper proposes an optimal algorithm using GA and SLP method where area, performance and power consumption can be simultaneously evaluated. As a result, the power/ground network is designed...
The optimal design of transmission system expansion planning is an important part of the overall planning task of electric power system under competitive electricity market environments. Taking the cost-benefit analysis theory in economics as a basis, this paper analyzes the economy and reliability of the power transmission network at the beginning. Then, a mathematical model cost/benefit is proposed,...
In this work, a novel design methodology is introduced to derive artificial magnetic conductor (AMC) screens with enhanced angular and frequency behaviours. The frequency and angular phase response are combined into a single two-dimensional map to visualize, in one single graph, the properties of the analyzed screen. The attention is also focused to the development of a genetic algorithm (GA) which...
The reliability and survivability of conventional communications systems in harsh mining environments has always been a problem. The extreme conditions such as falling rock, collapsing tunnels, fires, explosions and flooding, during which communications are needed most, can also render them inoperable. An emergency underground communication system needs to be very robust with respect to these and...
A generalized sensor network design algorithm for finding the optimal placement of sensors in a linear mass flow process has been developed and implemented. The algorithm developed in this work is based on a combination of concepts drawn from graph theory and genetic algorithms. The sensor network is designed to optimize a single criterion of cost, reliability or estimation accuracy, using a minimum...
