Conclusions -A class of redundant cascaded chains with i.i.d. modules is considered in which recovery from a failure takes place by replacing the faulty module by a spare module. The complexity of the reconfiguration process depends upon the location of spare modules in the cascade. This paper deals with the question of OPERATION AFTER THE FAILURE OF MODULE NUMBER 2 optimally placing the spare ...

Reliability allocation has an essential connection to design for reliability and is an important activity in the product design and development process. In determining the reliability of subsystems or components on the basis of goal reliability, attention must be paid to failure effect, failure information, and improvement opportunities based upon real potentials for reliability improvement. In...

service failure can put companies out of business if attention is not paid to this problem. the purposes of this study were to investigate the explanatory relationships between hotel guests’ perceptions of (a) service failure; (b) service recovery strategies in each service failure situation and behavioral intentions. this study explained the components of service recovery strategies used when ...

In this paper, the reliability allocation and index of overall cost rotary ultrasonic vibration-assisted EDM machine tool were studied. The failure rate each module can be accurately predicted by maximum entropy ordered weighted average algorithm so that corrected maintenance predicted. And effective control preventive costs achieved selecting best times under premise reliability. corrective re...

making capital and investment is the main driving forces of economic development. based on the investment sensitivity to the changes of some of macro-economic variables and risk and uncertainty, the present study evaluated the effective factors on investment in private sector in iran during 1980-2007. at first, the uncertainty variables of real informal exchange rate, nominal interest rate and ...

In this paper we introduce a new class of modules which is closely related to the class of Noetherian modules. Let $R$ be a commutative ring with identity and let $M$ be an $R$-module such that $Nil(M)$ is a divided prime submodule of $M$. $M$ is called a Nonnil-Noetherian $R$-module if every nonnil submodule of $M$ is finitely generated. We prove that many of the properties of Noetherian modul...
