Research ArticleOpen accessIn the keywordsA NOVEL OPTIMIZATION MODEL FOR SIMULTANEOUS COST-RISK REDUCTION IN MULTI-SUPPLIERS JUST-IN-TIME SYSTEMSFaraj El Dabee, Romeo Marian, Yousef AmerIn today’s competitive global markets, Just-in-Time (JIT) is one of the main lean manufacturing approaches. It is used in organizations to improve performance and reduce costs and as a strategic core capability to ensure their market position. However, using JIT tightly couples various functions of the Supply Chain and increases the risk of propagating disruptions through the entire system. This … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 7,614 accessesView PDFCite
Research ArticleOpen accessIn the keywordsScheduling of Automated Guided Vehicle and Flexible Jobshop using Jumping Genes Genetic AlgorithmP. Paul Pandian, S. Saravana Sankar, S. G. Ponnambalam, M. Victor RajProblem statement: Now a day’s many researchers try Genetic algorithm based optimization to find near optimal solution for flexible job shop. It is a global search. In Our study in the GA, some changes are made to search locally and globally by adding jumping genes operation. A typical flexible job shop model is considered for this research study. For that … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 7,311 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDerivation of the Limits for Control Chart Using the Median Absolute Deviation for Monitoring Non-Normal ProcessK. S. Adekeye, P. I. AzubuikeProblem statement: The Shewhart and S control charts, in the literature, were combined to evaluate the stability of a process. These charts were based on the fundamental assumption of normality of the quality characteristics under investigation. Approach: In practice, the normality assumption was often violated by real life data, therefore, use of the Shewhart and S control charts on real … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 24 Dec 2011 · 8,440 accessesView PDFCite

Problem statement: Studying the Contact Forms in Wafer Chemical Mechanical Polishing. Approach: A series test on the abrasion behavior and the lubricating behavior was conducted and then the test results were investigated by the abrasion and lubrication theory. Results: By the test results … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 7,286 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCost Optimization of Composite I Beam Floor SystemUroš Klanšek, Stojan KravanjaThe paper presents the cost optimization of the composite I beam floor system. The composite I beam floor system is designed to be constructed up of a reinforced concrete slab and doubly-symmetrical welded steel I beams. The optimization was performed by the nonlinear programming approach, NLP. An accurate objective function of the manufacturing material, power and labour costs was developed … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,439 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Scheduling Algorithm Based on Petri Nets and Simulated AnnealingRachida Hadiby Ghoul, Abdelhamid Benjelloul, Sihem Kechida, Hicham TebbikhThis study aims at presenting a hybrid Flexible Manufacturing System "HFMS" short-term scheduling problem. Based on the art state of general scheduling algorithms, we present the meta-heuristic, we have decided to apply for a given example of HFMS. That was the study of Simulated Annealing Algorithm SA. The HFMS model based on hierarchical Petri nets, was used to represent static … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the keywordsManpower Consideration to Reduce Development Time for New Model in Automotive IndustryN. M.Z.N. Mohamed, H. Y. Sastra, S. M. Sapuan et al.A study of manpower consideration to reduce development time for new model in automotive industry is presented in this study. The approach taken are by studying the existing practice in car development and suggesting various ways for manpower improvement such as through early involvement and input from manufacturing personnel, the proper job scope structure, proper training to the new staffs … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,980 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDefect Detection on 3D Print Products and in Concrete Structures Using Image Processing and Convolution Neural NetworkSelorm Garfo, M.A. Muktadir, Sun YiThis paper explores the automated detection of surface defects on 3-D printed products and concrete structures. They are the main factors to evaluate their quality in addition to dimension and roughness. Traditional detection by human inspectors is far from satisfactory. Manual inspection is time-consuming, error-prone and often leads to loss of resources. For this purpose, image processing and deep learning-based … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 26 May 2020 · 12,619 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHoneycomb Sandwich Specimens Made of PLA and Produced Via 3D FDM Printing Process: An Experimental StudySalvatore Brischetto, Roberto TorreIn recent years, the 3D Fused Deposition Modelling (FDM) technology, usually employed for the production of nonstructural objects, has been also used by the present authors for the production of small structural elements where the applied loads are moderate. A typical application could be the production of small Unmanned Aerial Vehicles (UAVs) where stresses are not excessive. In these cases, … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 25 May 2020 · 11,915 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Development of an Ergonomic Milling Machine Control Knob using TRIZ PrinciplesPoh Kiat Ng, Kian Siong JeeTRIZ, a Russian abbreviation known as the Theory of Inventive Problem Solving, refers to a methodology for problem-solving rooted in logic and data rather than intuition. It promotes the ability to solve problems creatively. Using TRIZ tools for problem-solving such as the cause-effect-chain analysis and engineering contradiction, a new ergonomic milling machine control knob was developed for improved musculoskeletal comfort. … …American Journal of Applied Sciences, Vol. 13, Issue 4 · 28 Apr 2016 · 7,790 accessesView PDFCite
