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....

In this paper, we develop an optimization model for the economic design of repetitive sampling plan in the presence of two markets. The process under consideration produces a product with a normally distributed quality characteristic with unknown mean and known variance. The quality characteristic has a lower specification limit. The quality of the product is controlled via lot-by-lot acceptanc...

The Shewhart, Bonferroni-adjustment and analysis of means (ANOM) control chart are typically applied to monitor the mean of a quality characteristic. The Shewhart and Bonferroni procedure are utilized to recognize special causes in production process, where the control limits are constructed by assuming normal distribution for known parameters (mean and standard deviation), and approximately no...

The translative intersection formula of integral geometry yields an expression for the mean Euler characteristic a stationary random closed set intersected with fixed observation window. We formulate this result in setting sets positive reach and using flag measures which yield curvature as marginals. As application, we consider excursion fields $C^{1,1}$ realizations, particular, Gaussian fiel...

in order to study the effect of grapeguard on quality, quantity and control of storage diseases of grape in cold storage a completely randomized design with 3 replicate was conducted on two cultivators of kolahdari and kajanguri in khorasan agricultural research center. the fruits after harvesting were transferred to the sheltered place. before keeping in cold storage, the temperature of fruits...

OBJECTIVE The 36-Item Short Form Health Survey (SF-36) is widely validated and popularly used in assessing the subjective quality of life (QOL) of patients and the general public. The aim of the study is to assess the psychometric properties of the 36-Item Short Form Health Survey (SF-36) in medical students in mainland of China. METHODS The reliability and validity of the 36-Item Short Form ...
