Research ArticleOpen accessPhrase in the titleThe Efficiency Measurement of Parallel Production Systems: A Non-radial Data Envelopment Analysis ModelAli Ashrafi, Azmi Bin Jaafar, Mohd Rizam Abu Bakar, Lai Soon LeeProblem statement: Data Envelopment Analysis (DEA) is a non-parametric technique for measuring the relative efficiency of a set of production systems or Decision Making Units (DMU) that have multiple inputs and outputs. Sometimes, DMUs have a parallel structure, in which systems composed of parallel units work individually; the sum of their own inputs/outputs is the input/output of the system. For … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 9,253 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAn Optimal Control Approach to Inventory-Production Systems with Weibull Distributed DeteriorationMd. Azizul Baten, Anton Abdulbasah KamilProblem statement: We studied the inventory-production system with two-parameter Weibull distributed deterioration items. Approach: The inventory model was developed as linear optimal control problem and by the Pontryagin maximum principle, the optimal control problem was solved analytically to obtain the optimal solution of the problem. Results: It was then illustrated with the help of an example. By the principle of … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,549 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleAssessment of Poultry Production System in Rwanda, A Case Study in Nyagatare DistrictMazimpaka Eugene, Mahoro Janvier, E.N. Tuyisenge, Ojok LonzyA cross sectional study was conducted on 160 indigenous poultry farmers in Nyagatare District to assess the effect of poultry cages on increasing poultry production in smallholder low cost village poultry farmers in Nyagatare district. Data were collected through pre-tested semi-structured questionnaires, participatory rural appraisal, observations and interviews. Most of farmers kept the dwarf type of local chicken (53.5%), night … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 1 · 9 Jan 2020 · 7,742 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleLong-term Effect of Conventional and No-Tillage Production Systems on Nitrous Oxide Fluxes from Corn (Zea mays L.) Field in Southwestern QuebecAbdirashid Elmi, Bano Mehdi, Chandra Madramootoo et al.Problem statement: There is a growing trend in the adoption of conservation tillage as an alternative to conventional tillage farming system. Implications of this agricultural management shift with respect to nitrous oxide (N2O) emission, which has been a topic of intense research for the past few decades, is not yet completely understood. Approach: This study was conducted on a 2.4 … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,016 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleEfficiency and Sustainability of Alternative Protein Sources for Livestock Production in Sub-Saharan Africa: A Systematic Review and Meta-AnalysisOlusegun Oyebade Ikusika, Bulo Luvuyo, Jaja Ishmeal FestusSub-Saharan Africa (SSA) faces growing challenges in sustainable livestock production due to high costs and limited availability of conventional protein sources such as soybean meal and fishmeal. This systematic review and meta-analysis evaluated the nutritional efficiency and sustainability of locally available alternative protein sources for livestock feed in SSA. Following PRISMA guidelines, systematic searches were conducted across five databases (PubMed, … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 19 Feb 2026 · 1,844 accessesView PDFCite
Literature ReviewOpen accessEvery word in the titleSystematic Review of Single Nucleotide Polymorphisms of Cattle Beta-Lactoglobulin Gene and their Association with Milk Production TraitsThlarihani Cynthia Makamu, Thobela Louis TyasiThe application of molecular genetics technology to pinpoint certain DNA markers associated with commercially significant features is highly anticipated since it has the potential to enhance the effectiveness of breeding programs by selecting young animals early for use as future breeding stock. One of the main genes expressed in bovine milk is the Beta-Lactoglobulin Gene (βLG), and its polymorphism can … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 4 Mar 2024 · 5,811 accessesView PDFCite

Research ArticleOpen accessEvery word in the titlePedagogical Resources Indexation Based on Ontology in Intelligent Recommendation System for Contents Production in d-Learning EnvironmentBrahim Faqihi, Najima Daoudi, Imane Hilal, Rachida AjhounWe witness, today, a strong evolution of learning environments. In parallel, a problem has emerged, consisting in how to capitalize the production of resources when switching from one environment to another. The heterogeneity of the environments, the evolution of the platforms and the will to reuse the educational resources already produced pushed us to design an intelligent system based on … …Journal of Computer Science, Vol. 16, Issue 7 · 19 Aug 2020 · 6,703 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstablishing an Adaptive Production-Procurement System with Markov Chain Approach Associated with 3C TheoryChun-Ta LinProblem statement: In this study, we classify the imperfect situations that the unreliability of production and the defective products might be incurred from production process into eight independently recurrent categories. Approach: With the property of recurrence of Markov chain, the limiting probability of each imperfect production category can be calculated through the transition probabilities matrix generated from these imperfect production … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,352 accessesView PDFCite
