Configuration design is considered effective in early stage of product design. This paper studies a configuration method based on constraints and fuzzy decision for product family. The configuration method is evolved from constraint based product configuration. It employs fuzzy optimum selection in the reasoning process, which can select similar components when customers’ requirements can not be met precisely. In the configurator, product family is represented with GBOM(Generic Bill Of Material) and ACL(Article Characteristic List). Every node of GBOM has an ACL to list all instances of a component family. Constraints are attached to every node, which involves variable definition and constraints definition. In the reasoning process, constraint satisfaction and fuzzy optimum selection interact to search optimum solution. A prototype is developted to demonstrate how to run the configurator. The paper ends with a discussion of advantages, future work of the configuration method.展开更多

And a follow-up study was also conducted on them. In the experimental s tudy, delayed allergic model mice were treated with immunosuppressor(cyclophosph amide) and LY separately to observe the effects on their immune function and inh ibition of vaginal epithelial cell proliferation. Results: In the observed group, 8 patients (5%) were cured, 32 (20%) basically cured, 48 (30%) markedly improved, 48 (30%) improved and 24 (15%) unchanged, the total effective rate being 85%, while in the control group, the corresponding numbers were 4, 8 , 14, 38, 36 and 64% respectively, with the comparison of the total effective ra te between the two groups showing significant difference( P <0.01). Adverse r eactions were not found in the study. Experimental study showed that LY could e nhance the immune function of mice and had a certain inhibitory effect on vagina l epithelial cell proliferation. Conclusion: LY could treat PM effectively and shows immune enhan cing and anti-mitosis effect in mice.展开更多
