Research ArticleOpen accessIn the author namesIs Wright Test an Appropriate Screening Test for Diagnosis of Brucellosis?Behzad Mohsenpour, Shahla Afrasiabian, Katayoon Hajibagheri, Ebrahim GhaderiProblem statement: Diagnosis of brucellosis is generally based on culture, polymerase chain reaction and serology. The first two methods are not accessible in all parts of world and are expensive. The routine method for diagnosis of brucellosis is considering Wright test as the first screening test; if the results are Wright positive’ Wright would be the next choice otherwise 2ME … …American Journal of Infectious Diseases, Vol. 7, Issue 2 · 17 Sep 2011 · 16,762 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Fuzzy Mathematical Programming Approach to DEA ModelsA. Azadeh, S.F. Ghaderi, Z. Javaheri, M. SaberiEvaluating the performance of activities or organizations by traditional Data Envelopment Analysis (DEA) as efficiency frontier analysis models requires crisp input/output data. However, in real-world problems inputs and outputs are often imprecise. This study develops DEA models using imprecise data represented by fuzzy sets. An important outcome of assessing relative efficiencies within a group of Decision Making Units (DMUs) in … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the author namesOptimization of an Automatic Blast Furnace through Integrated Simulation ModelingAli Azadeh, S. F. GhaderiThe objective of this study was to develop an integrated simulation model of an automatic blast furnace in a full-scale steelmaking factory. The integrated simulation model introduces a set of optimizing alternatives through sensitivity analysis. The simulation model is built by considering all major and detailed operations and interacting systems of the blast furnace workshop. The workshop is composed two … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,092 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Framework for Design of Intelligent Simulation EnvironmentAli Azadeh, Farid GhaderiThis study describes a framework for design and development of intelligent simulation environment. The intelligent simulation environment prescribes an integrated rule-based approach to simulate and optimize a manufacturing system. An intelligent simulation model is a computer program capable of improving its performance by referring to production constraints, system's limitations and desired targets. It is a goal oriented, flexible and integrated … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,702 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnalyzing the Electricity Consumption Using Experimental Design TechniqueS. F. Ghaderi, M. A. Azadeh, Sh. BamdadExperimental design technique is a powerful tool that is used in uncertainty cases, when a great amount of data is available. In this paper, the effects of different factors on the determination of electricity consumption are analyzed. This analysis is based on experimental design technique. The implementation of the proposed technique is shown applying electricity consumption in Iran. …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,584 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Total Productivity PCA Model for Assessment and Improvement of Electrical Manufacturing SystemsAli Azadeh, Farid GhaderiThis study presents a framework for assessment of electrical manufacturing systems based on a total machine productivity approach and multivariate analysis. Furthermore, the total model is developed by Principle Component Analysis (PCA) and validated and verified by Numerical Taxonomy (NT) and non-parametric correlation methods, namely, Spearman correlation experiment and Kendall Tau. To achieve the objectives of this study, a comprehensive … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,270 accessesView PDFCite
