讨论了Fuzzy模型P=A B=(p1,p2,…,pn)的算法规则 的三种情形。
We discuss three conditions of algorithm rule about Fuzzy model P=AB=(p1,p2,…,pn), that is Pj=max1in[min(αi,rij)],pj=∑ni=1αirij,Pj=∑ni=1min(αi,rij), and two Assessmental rules (1) simple assessment: If pk=max1jmpj, it is assessed to the kth grade; (2) comprehensive assessment:If ∑k-1j=1pj∑mj=kpj and ∑mj=k+1pj∑k-1j=1pj, it is assessed to the kth grade. If ∑k-1j=1pj∑mj=kpj and ∑k-2j=1pj∑mj=k-1pj, it is assessed to the (k-1)th grade. If ∑mj=k+1pj∑k-1j=1pj and ∑k-1j=1pj∑mj=kpj,it is assessed to the (k+1)th grade. If Fuzzy attaching degree rij contains a certain practical meaning, there are three theorems which may lead to misjudgement. Therefore, on the condition of the three theorems, both the single determination and joint determination are determined klevel. But they shouldn't be decided as Klevel if rij contains some practical meanings. At the same time, the writer puts forward some measures to avoid causing misjudgement.
