In the current study, the qualitative status of potable well water was assessed using the groundwater quality index during a course of 4 years (2014-2017). This study was carried out with an aim to monitor the drinking water resources from 12 potable wells on the multivariate analysis basis and for determination of groundwater quality index, the following 13 physicochemical parameters including...

In this manuscript, the reliability of a robotic system has been analyzed using the available data (containing vagueness, uncertainty, etc). Quantification of involved uncertainties is done through data fuzzification using triangular fuzzy numbers with known spreads as suggested by system experts. With fuzzified data, if the existing fuzzy lambda–tau (FLT) technique is employed, then the comput...

seasonal variations of climatic parameters are significant in arid and semi-arid regions and sensitivity of each parameter may differ in different seasons. no work has been done in this regard in iran. therefore, in this study, sensitivity analysis of the asce-penman-monteith grass reference evapotranspiration (eto) equation was investigated on the basis of variation of mean air temperature (tm...

this paper presents an economic evaluation of gas to liquids (gtl) project using “south-pars” gas field of iran based on the latest actual performing gtl projects. iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of gtl products which have lower pollution and higher quality than refinery products. the results of cost-benefit analysis sho...

Most of data in a multi attribute decision making (MADM) problem are unstable and changeable, and thus sensitivity analysis can effectively contribute to making proper decisions. Here, we offer a new method for sensitivity analysis of multi-attribute decision making problems so that by changing one element of decision making matrix, we can determine changes in the results of a decision making p...

This paper is concerned with the sensitivity analysis of GI/GI/1 queueing model by “push-out” simulation technique, which is based on discrete event dynamic system using structural parameters. The study of “push-out” technique is extension of score function simulation method for sensitivity analysis and stochastic optimization.

this study aimed to measure the hospital productivity using data envelopment analysis (dea) technique and malmquist indices.this is a cross sectional study in which the panel data were used in a 4 year period from 2007 to 2010. the research was implemented in 12 teaching and non-teaching hospitals of ahvaz county. data envelopment analysis technique and the malmquist indices with an input-orien...
