Research ArticleOpen accessPhrase in the titleA Note on the Analysis of Time Cost by Difference of Transaction System in the Agricultural Wholesale Market of KoreaYoon-Doo Kim, Seok YoonProblem statement: The purpose of this study is to prove objectively that the market-wholesaler system, introduced to agricultural wholesale market in Korea for the first time, has better operational efficiency than the existing auction system. From an analytical viewpoint, we estimated the time value of two transaction systems at the agricultural wholesale market using the calculation methods of the congestion … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 23 Jan 2012 · 7,706 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA GENETIC ALGORITHM FOR A SIMULTANEOUS OPTIMISATION OF COST-RISK REDUCTION UNDER A JUST-IN-TIME ADAPTIONFaraj El Dabee, Romeo Marian, Yousef AmerJust-In-Time (JIT) as a lean manufacturing approach plays a significant role in minimising costs and performances of products and services supplied to the global marketplace. However, there are many potential risks that cause significant disruptions to all supply chain members. This study proposes a genetic approach for optimising a novel mathematical model for simultaneously minimising the total cost of a … …Journal of Computer Science, Vol. 10, Issue 12 · 26 Dec 2014 · 7,695 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA 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 accessEvery word in the titleConstrained Probabilistic Economic Order Quantity Model under Varying Order Cost and Zero Lead Time Via Geometric ProgrammingKotb Abd-El-Hamid Mahmoud Kotb, Huda Mohamed Hamid Al-ShanbariProblem statement: In this study, we provide a simple method to determine the inventory policy of probabilistic single-item Economic Order Quantity (EOQ) model, that has varying order cost and zero lead time. The model is restricted to the expected holding cost and the expected available limited storage space. Approach: The annual expected total cost is composed of three components (expected … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 3 Nov 2011 · 7,614 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePeriodic Review Probabilistic Multi-Item Inventory System with Zero Lead Time under Constraint and Varying Holding CostNaglaa Hassan El-SodanyProblem statement: This study treats the probabilistic safety stock n-items inventory system having varying holding cost and zero lead-time subject to linear constraint. Approach: The expected total cost is composed of three components: the average purchase cost; the expected order cost and the expected holding cost. Results: The policy variables for this model are the number of periods N*r and … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 29 Jan 2011 · 7,526 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePeriodic Review Probabilistic Multi-Item Inventory System with Zero Lead Time under Constraints and Varying Order CostHala A. FerganyThis study treats the probabilistic safety stock n-items inventory system having varying order cost and zero lead-time subject to two linear constraints. The expected total cost is composed of three components: the average purchase cost; the expected order cost and the expected holding cost. The policy variables in this model are the number of periods Nr* and the optimal maximum … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,634 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Linear Chouquet Integral Algorithm to Design Optimal Time-Cost Model in Large Construction ProjectsHamid Jafari Nia, Kaveh Ostad-Ali-Askari, Hamidreza BabaaliNowadays, the problem of scheduling and executing projects with the least cost and time has become one of the main concerns of project managers. In this regard, researchers have used different methods and patterns. One of these methods is to use concurrent engineering in projects. Simultaneous engineering means the creation of a project schedule for projects based on existing units … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 18 Nov 2020 · 6,689 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTime-Driven Activity-Based Costing in the Public Sector. The Case of Greek General Chemical State Laboratory under the Greek CrisisAthanasios Vazakidis, Eleftheria KyriakidouThe international globalized environment and the financial crisis have generated new demands with internals (citizens-users) and externals (creditors) pressuring the governments to control public spending and improve efficiency in the supply of public goods/services. The control of the public sector costs seems more important now, in the context of the financial and fiscal crisis of 2008. Activity Based Costing (ABC) … …Journal of Social Sciences, Vol. 16, Issue 1 · 4 Mar 2020 · 7,954 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInventory Models with Power Demand and Inventory-Induced Demand with Holding Cost FunctionsRakesh Prakash Tripathi, Sarla Pareek, Manjit KaurIn real life customers are motivated to buy more if there is more availability of product. In this study, we develop inventory model for inventory dependent demand with different holding cost function. Mathematical formulations are discussed for two situations i.e., power demand rate with inventory dependent holding cost functions and inventory-induced demand rate with time and inventory dependent holding cost … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 6 Apr 2017 · 7,544 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSecondary User Sensing Time Optimization in Sensing-Transmission Scheduling for Dynamic Spectrum Access in Cognitive RadioInderdeep Kaur Aulakh, Renu VigThe constraint of limited frequency spectrum for wireless communication is very daunting. The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a change in regulation of radio spectrum. In cognitive radio networks a secondary user network is designed for efficiently using gaps in spectrum and not causing at the same … …Journal of Computer Science, Vol. 11, Issue 8 · 5 Nov 2015 · 7,349 accessesView PDFCite
