In this study, we proposed a method to find the fuzzy reliability of the network using fuzzy sum-of-disjoint product technique. We use the fuzzy graph theory techniques for addressing the reliability of a network with known minimal paths. We have also presented an efficient algorithm to find the reliability of the network.

Background: Considering the importance of preventing smoking hookah in adolescents and the lack of a standard questionnaire in this field, this study aimed to develop and validate a Persian Preventing Hookah Smoking (PHS) Questionnaire in adolescents based on the Protection Motivation Theory. Materials and Methods: After conducting focus groups discussion, reviewing the literature and scientifi...

In this issue, Gafni et al.1 provide a strong and timely case for evaluating the reliability and validity of multi-station selection centres (SCs, sometimes referred to as assessment centres). In developing this important research topic, we highlight: (i) important differences between SCs and objective structured clinical examinations (OSCEs); (ii) the importance of demonstrating the construct ...

Service reliability in a distributed queuing system can be assessed by means of the probability of successfully serving queued tasks in a heterogeneous network of nodes. Moreover, randomness in delays imposed by the communication medium adds to the uncertainties in the shared information among these faulty nodes, which complicates the dynamics of the queuing system. A novel approach based on st...

To develop a general reliability theory taking into account various sources of information and a lack of satisfactory data on which estimates of system parameters can be based, the theory of imprecise probabilities can be used. The purpose of the paper is to study structural reliability based on the imprecise probability models taking into account the ageing aspect of the lifetime distributions...

Medical Surgical Nursing is one of the major subjects in nursing. This study examined the validity and reliability of the achievement examination utilizing the Classical Test Theory and Item Response Theory. The study answered the following objectives specifically : ( a) To establish the validity and reliability of the achievement examination utilizing Classical Test Theory and Item Response Th...

Abstract To improve organisational safety and enhance security efficiency, organisations seek to establish a culture of that provides foundation for how employees should approach security. There are several frameworks models provide set requirements forming cultures; however, many organisations, the difficult meet, if not impossible. In this research, we take different perspective focus on core...

Recently, analysis and designing of the structures based on the Reliability theory have been the center of attention. Reason of this attention is the existence of the natural and random structural parameters such as the material specification, external loads, geometric dimensions etc. By means of the Reliability theory, uncertainties resulted from the statistical nature of the structural parame...

This thesis proposes a safety instrument system which is based on D-S evidence theory, including sensor, logic voting system and execution unit. While the logic voting system concludes the input circuit, processor, output circuit and the diagnosis module based on D-S evidence theory. According to the diagnosis module in multi-channel logic voting system and calculation based on D-S evidence the...

introduction: measuring tools in each study must be evaluated themselves. the goal of present study was designing, validating, and determining the reliability of some scales, which are used for measuring concepts of behavior change theory/models. materials & methods: this study was a descriptive one in which, at first literature review and need assessment were done. then designed tools were val...
