[ 1 ] - کاربرد روش های چند معیاره در رتبه بندی تامین کنندگان قطعات (مطالعه موردی)
تحقیق در بازار خرید و انتخاب مناسب ترین تامین کننده، یکی از مهمترین فعالیت ها در سازمان های امروزی است. عدم توجه به شرایط تامین قطعات و مواد اولیه در هر سیستم و همکاری با تامین کنندگان ممکن است به افزایش هزینه های خرید و خدمات نهائی منجر گردد. رتبه بندی و انتخاب تامین کنندگان به منظور همکاری در تامین قطعات باید با توجه به چندین معیار و شاخص صورت گیرد. در مقاله حاضر جهت ارزیابی و رتبه بندی تامین...
[ 2 ] - A continuous approximation fitting to the discrete distributions using ODE
The probability density functions fitting to the discrete probability functions has always been needed, and very important. This paper is fitting the continuous curves which are probability density functions to the binomial probability functions, negative binomial geometrics, poisson and hypergeometric. The main key in these fittings is the use of the derivative concept and common differential ...
[ 3 ] - On Different Characteristics of Iranian Farmer Women in Rural Development Activities Based on Animal Husbandry
Rural women play a significant role in domestic and socio-economic life of the society so that national development is not possible without developing this important and substantial segment of our society. Given the importance of women in agriculture, this study was conducted to examine the role of Iranian women in the farm management decision-making processed concerning animal husbandry. The s...
[ 4 ] - Bayesian Sample Size Computing for Estimation of Binomial Proportions using p-tolerance with the Lowest Posterior Loss
This paper is devoted to computing the sample size of binomial distribution with Bayesian approach. The quadratic loss function is considered and three criterions are applied to obtain p-tolerance regions with the lowest posterior loss. These criterions are: average length, average coverage and worst outcome.
