in quality control charts, the problem of determining the optimum process mean arises when the deviation of a quality characteristic in one direction is more harmful than in the opposite direction. the failure mode in these two directions is usually different. a great majority of researches in this area have considered asymmet-ric cost function for processes with single quality characteristics....

this paper is devoted to the study of determining optimal process mean in system production with the two markets for the sale of goods. in this paper, we developed an absorbing markov chain model in production systems where all items are inspected %100 for conformance with their specification limits. when the value of the quality characteristic of an item falls below a lower limit, the item is ...

a method based on machine vision system (mvs) is hereby employed to evaluate grape drying through an assessment of the fruit’s shrinkage and quality during the dehydration. experimental data as well as captured images are obtained at an air velocity of 1.4 m s-1 and different drying temperatures (50, 60, 70ºc). the results indicated the effect of temperature on the moisture content, shrinkage a...

multivariate process capability indices (mpci) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. process capability is an important and commonly used metric for assessing and improving the quality of a production process. when quality charac-teristics of a product are correlated then an attractive comes close to mpc...

background: using thinking-based scientific methods such as paper-based and electronic nursing processes in nursing education can lead to education of skilled and efficient experts that can affect students’ satisfaction in addition to their quality of care. the present study aimed to compare the effects of recording and implementing the nursing process based on two methods (paper-based and elec...

conclusions nursing process indicators can be used to audit nursing care. such audits can be used as quality assurance tools. results the compliance rate of nursing process indicators was 79.71 ± 0.87. mean compliance scores did not significantly differ by education level and gender. however, overall compliance scores were correlated with nurses’ age (r = 0.26, p = 0.001) and work experience (r...
