摘　　要：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=AB=(p1,p2,…,pn), that is Pj=max1in[min(αi,rij)],pj=∑ni=1αirij,Pj=∑ni=1min(αi,rij), and two Assessmental rules (1) simple assessment: If pk=max1jmpj, it is assessed to the kth grade; (2) comprehensive assessment:If ∑k-1j=1pj∑mj=kpj and ∑mj=k+1pj∑k-1j=1pj, it is assessed to the kth grade. If ∑k-1j=1pj∑mj=kpj and ∑k-2j=1pj∑mj=k-1pj, it is assessed to the (k-1)th grade. If ∑mj=k+1pj∑k-1j=1pj and ∑k-1j=1pj∑mj=kpj,it is assessed to the (k+1)th grade. If Fuzzy attaching degree rij 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 klevel. But they shouldn't be decided as Klevel if rij contains some practical meanings. At the same time, the writer puts forward some measures to avoid causing misjudgement.
