Most of the studies on inventory control reported in earlier contributions deal with the optimization problems minimizing an expected cost criterion such as the long-run average cost. However, when the plant engineers design the inventory systems in practical situations, they must take account of reliability into the inventory system as well as economical aspect, where reliability can be define...

CONTEXT The Balance Error Scoring System (BESS) is commonly used by researchers and clinicians to evaluate balance.A growing number of studies are using the BESS as an outcome measure beyond the scope of its original purpose. OBJECTIVE To provide an objective systematic review of the reliability and validity of the BESS. DATA SOURCES PubMed and CINHAL were searched using Balance Error Scori...

This chapter presents design of reliable networks. The exact calculation of any general network reliability measure is NP-hard. Therefore, network designers have been reluctant to use reliability as a design criterion. However, reliability is becoming an important concern to provide continuous service quality to network customers. The chapter discusses various network reliability measures and e...

In this paper, we have considered a series-parallel system to find out optimum system reliability with an additional entropy objective function. Maximum system reliability of series-parallel system is depending on proper allocation of redundancy component in different stage. The goal of entropy based reliability redundancy allocation problem is to find optimal number of redundancy component in ...

Due to the expected increase of defects in circuits based on deep submicron technologies, reliability has become an important design criterion. Although different approaches have been developed to estimate reliability in digital circuits and some measuring concepts have been separately presented to reveal the quality of analog circuit reliability in the literature, there is a gap to estimate re...

The aim of the study is to validate the questionnaire by using confirmatory factor analysis. Besides, it also would like to examine the internal reliability. Three hypotheses were tested. The questionnaires have been answered by 294 respondents among ten schools. The minimum criterion of model was achieved. The reliability of the questionnaires was high.

ABSTRACT Objective: to verify the validity and reliability of Psychological Distress Scale for screening mental distress. Methods: a cross-sectional study with 75 elderly people. scale Self Reporting Questionnaire were used. Criterion was verified using Spearman’s correlation diagnostic accuracy measures. Cronbach’s alpha coefficient used investigate reliability. Results: total internal consist...

Objectives: The follow-up treatment or rehabilitation and monitoring of patients with drug abuse disorders require an efficient tool with a convenient and short-time implementation to measure psychological aspects of dependence. The Leeds Dependence Questionnaire (LDQ) has such features; thus, the present study aimed at evaluating the validity and reliability of its Persian version. Methods: T...
