Engineering quality, quality management system components, and their relationship were defined. An integrated engineering quality system was decomposed into seven factors and the quality management system was composed of eight factors. Importance weights of all factors and their relationship point were acquired by questionnaires and interviews. Then, QFD matrix was formulated and the calculating process was proposed. This model was verified on a case study. The result shows that it is useful for contractor in benchmarking themselves and invaluable for owners in the process of deciding contractor.展开更多

Based on that the quality requirements are converted into designspecifications and technical measures step by step in this model, logical relationship factors canclassify the related Hows (how to do, the quality measures) into groups, each of which should belogical to individual What (what to do, the quality goal). Sequential factors can express theimplementing sequence of Hows. A feasibility evaluation method is proposed to eliminate the inferiorgroups of Hows. This improved QFD model can provide enough information to produce a practicalquality plan.展开更多

After lots of QFD application is applied in manufacturing fields,it was proved that without considering suppliers involved,it is difficult to get precise and satisfying results in each process of QFD,particularly part deployment. The paper will address the issues of a model of optional parts selection in suppliers involved in part deployment process. Further,it has been applied to an ERP system reconstruction and updating problem as an illustration.展开更多

Pregnant rats were fed the soybean milk（5% or 100% in drinking water）from gestational day（GD） 6 to parturition or to post-natal day（PND） 56. Specifically, the rats were divided into 4 groups： the control group（drinking water）, the GD5% group（5% soybean milk during only the GD period）, the GDPND5% group（5% soybean milk during the GD and PND periods）, and the GD-PND100% group（100% soybean milk instead of water during the GD and PND periods）. During the gestational, lactational, and developmental periods, the reproductive and developmental parameters of dams and offspring were observed. Feeding soybean milk did not affect the birth and physical development of both male and female offspring. At PND57, the weights of the testes and epididymides of F1 males significantly increased by feeding a high concentration of the soybean milk（GDPND100%）. In addition, feeding of the soybean milk during both the GD and PND periods（GD-PND5% and GDPND100%） enhanced the sperm counts and motility. The results indicate that soybean milk is safe for embryos,fetuses, and offspring, and improves the post-generational development of male reproductive function.展开更多
