Research ArticleOpen accessAll words, across the recordA Rigorous Mathematical Approach for Petrophysical Properties EstimationDario VibertiProblem statement: Over the last few decades, the oil industry has shown a growing interest in the new risk analysis methodologies aimed at the evaluation of the uncertainties associated with reservoir exploitation. In particular, the effort is made to take all possible sources of uncertainties into account so that not only the strengths but also the potential weaknesses of each … …American Journal of Applied Sciences, Vol. 7, Issue 11 · 8 Nov 2010 · 7,976 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA 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 accessAll words, across the recordReservoir Oscillations with Through FlowA.A. KhanThe two-reservoir problem with through flow is a common feature in wastewater treatment plants. The start of the through flow may cause water surface oscillations in the reservoirs and velocity variations in the connecting pipe during the initial unsteady phase that may adversely affect the operation and under certain conditions may cause overtopping of the upstream reservoir. The classical solution … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,030 accessesView PDFCite
