with the huge global and wide range of attention placed upon quality, promoting and optimize the reliability of the products during the design process has turned out to be a high priority. in this study, the researcher have adopted one of the existing models in the reliability science and propose a bi-objective model for redundancy allocation in the series-parallel systems in accordance with th...

this paper presents a new mathematical model for a redundancyallocation problem (rap) withcold-standby redundancy strategy and multiple component choices.the applications of the proposed model arecommon in electrical power, transformation,telecommunication systems,etc.manystudies have concentrated onone type of time-to-failure, butin thispaper, two components of time-to-failures which follow hy...

Series and parallel connections are usually first encountered in the study of electrical circuits. Our approach is to first examine a relevant class of partially ordered sets (posets) and then to define series-parallel networks by analogy [1]. Interesting asymptotic constants appear everywhere, similar to those associated with counting various species of trees [2]. We also talk briefly about th...

Cloud model has been used in the field of reliability evaluation successfully. It solves the problem of reliability evaluation under variable working conditions. In the past, most work was focused on the reliability evaluation of single product. For this reason, a hybrid method based on non-probabilistic cloud model and traditional probability statistics is proposed. It solves the reliability e...

In this paper, using supply chain operational reference, the reliability evaluation of available relationships in supply chain is investigated. For this purpose, in the first step, the chain under investigation is divided into several stages including first and second suppliers, initial and final customers, and the producing company. Based on the formed relationships between t...
