The cumulative count of conforming (CCC) chart is effective in detecting very low fraction of nonconforming items for high yield manufacturing processes. In this study, a combination of runs rules and variable sampling interval feature is proposed to a lower sided CCC chart by inspecting the items one by one. The performance measures of the control chart are derived by using the Markov chain approach. The numerical comparisons show that the performance of the CCC chart can be improved by adding the runs rules and varying the sampling interval. 相似文献

Crude divorce rates of overseas-born Australians by birthplace are not comparable because different birthplace groups have
different age structures and marriage patterns that affect the rates. This paper decomposes the crude rates into components
due to the effects of age structrue, marriage patterns and the divorce rate of married men and women. This allows for a better
comparison of the level of divorce by birthplace. The range in the standardized divorce rates by birthplace is smaller than
that indicated by the crude rates. Nonetheless, there remains considerable variation in immigrant divorce rates in Australia. 相似文献

This article details findings from social workers in Sweden and Canada, illuminating similarities and differences in gatekeeping in child welfare and child protection. Analysis revealed different patterns of inclusion and exclusion. Swedish child welfare includes a greater readiness to intervene with more resources and measures. Gatekeeping is assessment driven and focused on family preservation. In Canada, only the most needy children are eligible for a limited range of services. Gatekeeping is structure driven and narrowly focused on protection. Analyses of evidence-based research to improve outcomes for children and families must include comparisons of how different structural orientations influence management of referrals at intake. The authors discuss the implications of these findings. 相似文献

The article discusses five types of spouse migration. Data on the country of origin of migrant spouses and their sponsoring partners suggest that the largest component of spouse migration is chain migration for marriage, with previous immigrants sponsoring partners from their former home country. Other smaller components are sponsorship of spouses by the second generation from the parents' country of origin; sponsorship of foreign spouses by Australians for intermarriage; and family reunion of spouses separated by refugee movements. Spouse migration from English‐speaking or European countries is often motivated by a preference for Australia's climate or lifestyle rather than marriage to an Australian partner, unlike spouse migration from other parts of the world where the process is more closely related to marriage. 相似文献

AbstractAn economic-statistical design of the synthetic double sampling (synDS) T2 chart is presented in this study. The cost function is minimized to obtain the optimal design parameters of the synDS T2 chart by incorporating the statistical constraints or the constraints on the average number of samples. An example is provided and a sensitivity analysis is conducted to study the effect of model parameters on the optimal solution of the design. The numerical comparison shows that the synDS T2 chart performs better than the synthetic T2 chart and the multivariate exponentially weighted moving average chart, in terms of the cost. 相似文献
