In this paper, one of the most important criterion in public services quality named availability is evaluated by using artificial neural network (ANN). In addition, the availability values are predicted for future periods by using exponential weighted moving average (EWMA) scheme and some time series models (TSM) including autoregressive (AR), moving average (MA) and autoregressive moving avera...

to determine the coverage rate, timeliness and quality of ante-natal care in rural areas under the coverage of health houses in west azerbaijan province, 30 health houses (hh) were randomly selected out of 731 hh in the province. in each hh, using the method of lot quality assurance sampling (lqas) 28 women having recently born babies was selected. data were collected using check-list for facil...

The mixed control chart is proposed to improve detection performance with fewer process shifts. In this study, we the modified exponentially weighted moving average - (MMEM), a new for observing changes in mean. Average run length, standard deviation of and median length can be used examine effectiveness detecting Shewhart, Moving (MA), Modified Exponentially Weighted (MEWMA), Mixed (MMME) char...
