in order to  study of environment × genotype interaction and selection of stable and high yielding and cold  tolerant chickpea lines, this study carried out  with 13 chickpea genotypes along with one local check (jam) in a rcb design with four replications during three cropping seasons (2009-2012) in agricultural research station of maragheh (dari). the genotypes were exposed to cold temperatur...

Discrete-event simulation based optimization is the process of finding the optimum design of a stochastic system when the performance measure(s) could only be estimated via simulation. Randomness in simulation outputs often challenges the correct selection of the optimum. We propose an algorithm that merges Ranking and Selection procedures with a large class of random search methods for continu...

Proper selection of material in manufacturing firms is a vital role of designer depending upon the different era of application. The material selection problem is very complex and challenging task today. Erroneous cull of material frequently leads to astronomically immense cost involution, and finally drives towards unfortunate component or product breakdown. Thus, the designer necessitates dis...

A fundamental problem in business and other applications is ranking items with respect to some notion of profit based on historical transactions. The difficulty is that the profit of one item not only comes from its own sales, but also from its influence on the sales of other items, that is, the “cross-selling effect”. In this thesis, we draw an analogy between this influence and the mutual rei...

This paper considers the problem of learning the ranking of' a set of' stochastic alternatives based upon incomplete information (i.e., a limited number of samples). We describe a system that, at each decision cycle, outputs either a complete ordering on the hypotheses or decides to gather additional information (Le., observations) at some cost. The ranking problem is a generalization of the pr...

Background and Objectives: The selection of the sustainable supplier is important for any industry. Medical centers are not an exception in this case, and selecting the best sustainable supplier is a major step towards increasing their productivity. This paper, using the Data Envelopment Analysis and then using Multi-Attributed Utility Theory as a backup approach to fix errors, attempts t...

abstract this study was conducted to evaluate the resistance of 70 genotypes of barley to powdery mildew. after preparing the samples contaminated with powdery mildew, reproduction of the spores of the fungus was conducted on susceptible cultivar afzal. the experiment was conducted with randomized block design in pot in greenhouse. seedlings were inoculated with the spores fungus in two-leaf st...

increasing global notices in environmental protection, green supply chain management (gscm) has received much attention by researchers and managers more than the past. commonly, firms have considered cost criteria to select their suppliers. despite the fact that there are various papers considering the formal criteria in supplier selection, there is a few limited numbers considering the environ...
