Research ArticleOpen accessEvery word in the titleEconomic Order Quantity with Linearly Time Dependent Demand Rate and ShortagesR. P. Tripathi, D. Singh, Tushita MishraThis paper presents an inventory model with linearly time dependent rate and shortages under trade credits. We show that the total cost per unit is convex function of time. Some properties have also been discussed based an optimal solution. The results are discussed with the help of numerical examples. Sensitivity analyses with a variety of numerical results showing the effect … …Journal of Mathematics and Statistics, Vol. 11, Issue 1 · 26 Jun 2015 · 7,008 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleArtificial Shortages and Strategic PricingMouataz Zreika, Partha GangopadhyayProblem statement: We consider a monopolist who manipulates the market by artificially creating shortages that result in an increase in current price that, in turn, boosts demand for the product in subsequent periods. The approach is to develop an intertemporal model of pricing strategy for a monopolist. Approach: The postulated pricing strategy creates an incentive for producers to reduce current … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 16 Feb 2012 · 7,251 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPolicy Decisions for a Price Dependent Demand Rate Inventory Model with Progressive Payments SchemeMukesh Kumar, Rajat KumarProblem statement: In this proposed research, we developed an inventory model to formulate an optimal ordering policies for supplier who offers progressive permissible delay periods to the retailer to settle his/her account. We assumed that the annual demand rate as a decreasing function of price with constant rate of deterioration and time-varying holding cost. Shortages in inventory are allowed which … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 17 Feb 2012 · 7,053 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnvironmental Issues in Jordan, Solutions and RecommendationsNidal A. Hadadin, Zeyad S. TarawnehJordan’s natural resources are limited to support population in a sustainable manner. However, its environment is exposed to a number of threats. In order to best explain Jordan’s environmental difficulties, it would be prudent to focus individually on each of these major concerns: water shortages, agriculture/land and air pollution. This study focuses on the environmental problems in Jordan and has … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 10,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrend Analysis of Precipitation, Groundwater Level and Flow Rate Data by using Mann-Kendall and Sen's Slope Estimator Statistical Tests in the Petorca CommunerHéctor L. Venegas-Quiñones, Mark Thomasson, Pablo A. Garcia-ChevesichThis article analyses one of the most complex socio-environmental conflicts in Chile: The Petorca water crisis. Petorca has been experiencing a shortage of water for several years. The cause of these variations has not yet been completely analyzed and the problem has remained unchanged. This paper evaluates hydrology variables to identify, quantify and demonstrate the cause of water shortages in … …American Journal of Environmental Sciences, Vol. 15, Issue 6 · 10 Jan 2020 · 8,427 accessesView PDFCite
Case ReportOpen accessIn the abstractEvaluation of Seasonal Autoregressive Integrated Moving Average Models for River Flow ForecastingKassahun Birhanu Tadesse, Megersa Olumana Dinka, Tena Alamirew, Semu Ayalew MogesReservoir operation policies cannot be functional in instant decision making without forecasting the future reservoir inflows. For forecasting inflows into reservoirs with only hydrological data is available like Koga irrigation dam, multivariate forecasting models cannot be used to generate accurate river flow information. As a result, an evaluation of univariate Seasonal Autoregressive Integrated Moving Average (SARIMA) models was done for … …American Journal of Environmental Sciences, Vol. 13, Issue 5 · 28 Sep 2017 · 7,891 accessesView PDFCite

Research ArticleOpen accessIn the abstractAgro-Process Intensification through Synthetic Rhizosphere Media for Nitrogen Fixation and Yield Enhancement in PlantsG. Akay, D. R. BurkeProblem statement: In order to combat global warming and the emerging Food, Energy and Water shortages (FEWs), several approaches have been adopted, including genetic engineering and farming practices. Biomass based energy technology will further stress food and water resources and hence novel holistic approaches to FEWs should be designed. Approach: A novel technique (Agro-Process Intensification, A-PI) which simultaneously addresses FEWs … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 15 Mar 2012 · 8,603 accessesView PDFCite
