The investment evaluation of power grid construction projects is a necessary link for companies to carry out construction. In the traditional process, it generally based on original index scores or similar schemes comparison and decision-making. There are problems simple methods insufficient theoretical support. Fully considering various factors in process construction, set rating system with t...

in order to study genetic variation and relationship between traits, 615 accessions of local bread wheat from wheat collection of national plant gene bank of iran were evaluated. seeds of the accessions were planted in 2.5 meter long rows in an observatory design and 17 agro-morphological traits were measured. grain yield of 5 spikes, number of tillers and number of seeds per spike were of high...

One of the difficulties of Data Envelopment Analysis(DEA) is the problem of deciency discriminationamong efficient Decision Making Units(DMUs) and hence, yielding large number of DMUs as efficientones. The main purpose of this paper is to overcome this inability. One of the methods for rankingefficient DMUs is minimizing the Coefficient of Variation (CV) for inputs-outputs weights. In this pape...

The coefficient of the variation function is a useful descriptive statistic, especially when comparing variability more than two curve groups, even they have significantly different mean curves. Since ratio and standard deviation functions, its particular property that it shows acceleration explicitly function. aim study twofold: to show functional sensitive abrupt changes propose utilisation a...
