Research ArticleOpen accessIn the abstractFlow Based AlgorithmT. Karpagam, V. J. Sudhakar, N. Arunsankar, M. DhanasekaranProblem statement: Network topology design problems find application in several real life scenario. Approach: Most designs in the past either optimize for a single criterion like shortest or cost minimization or maximum flow. Results: This study discussed about solving a multi objective network topology design problem for a realistic traffic model specifically in the pipeline transportation. Here flow based algorithm … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 22 Dec 2011 · 8,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractTuning of a Proportional-Integral-Derivative Controller using Multi-Objective Non Dominated Sorting Particle Swarm Optimization Applied to pH Control in Continuous Stirred Tank ReactorC. Agees Kumar, N. Kesavan NairProblem statement: Most of the control engineering problems are characterized by several, contradicting, conflicting objectives, which have to be satisfied simultaneously. Two widely used methods for finding the optimal solution to such problems are aggregating to a single criterion and using Pareto-optimal solutions. Approach: Non-Dominated Sorting Particle Swarm Optimization algorithm (NSPSO) based approach is used in the design of multiobjective … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 6,788 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling of Multi-Level Capacitated Lot-Size Scheduling ProblemZuhaimy Ismail, Diyana Abd Mahad, Tan Siew ChingProblem statement: Lot-size is the clustering of items for transportation or manufacturing processes occurring at the same time. The issue in lot-size problem is to design production processes so that the feasible production quantities are equal to customer demand quantities and the timing of production is such that inventory positions are almost zero. Approach: In this study, we explore the … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware Implementation of a Genetic Algorithm Based Canonical Singed Digit Multiplierless Fast Fourier Transform Processor for Multiband Orthogonal Frequency Division Multiplexing Ultra Wideband ApplicationsMahmud Benhamid, Masuri B. OthmanProblem statement: Ultra Wide Band (UWB) technology has attracted many researchers' attention due to its advantages and its great potential for future applications. The physical layer standard of Multi-band Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB system is defined by ECMA International. In this standard, the data sampling rate from the analog-to-digital converter to the physical layer is up to 528 … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractParallel Performance Monitoring Service for Dynamically Composed Media Web ServicesG. Maria Kalavathy, P. SeethalakshmiProblem statement: As distributed real-time multimedia services are accessed by users from different locations, the run-time performance must be managed and monitored to get a clear view of how media web services perform within their operational environments and to perform control actions to modify and adjust the their behavior. Otherwise it will provide negative effects on the reputation of service … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 7,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometric Optimization of Three-Phalanx Prosthesis Underactuated Fingers using Particles Swarm AlgorithmSomar M. Nacy, Shaker S. Hassan, Sadeq Hussein BakhyProblem statement: One are now interested to investigate the optimum design procedure for a finger driving mechanism to have a good configuration of the finger for its utilization in hand prosthesis. A Geometric Optimization of Three-Phalanx Prosthesis Underactuated Fingers (TPPUF) based on a Particle Swarm Optimization (PSO) was presented. Approach: Firstly, a numerical evaluation of the human-like motion was obtained … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,701 accessesView PDFCite

Research ArticleOpen accessIn the abstractNon-dominated Sorting Genetic Algorithms for Heterogeneous Embedded System DesignA. K. Rath, S. N. DehuriThe design of complex embedded systems involves the simultaneous optimization of several conflicting and competing objectives. Instead of a single global optimal solution, there exist a set of Pareto optimal solutions. In this study we have used a multi-objective evolutionary optimization algorithms called non-dominated sorting genetic algorithm (NSGA), which will suit to the requirements of designing a complex heterogeneous embedded … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,693 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImproved Meta-Heuristic for Multi-Objective Integrated Procurement, Production and Distribution Problem of Supply Chain Network Under Fuzziness UncertaintiesKaoutar Douaioui, Mouhsene Fri, Charif Mabrouki, El Alami SemmaIn this study, we devoted a design under uncertainty of a supply chain network composed of multiple suppliers, multiple plants, multiple distributors and multiple customers. The proposed model is a bi- objective mixed integer linear programming which consider several constraints and optimize the total costs including the procurement, production, storage and distribution costs as well as maximize on-time deliveries.
