pij is the priority value of the jth criteria belonging to the ith criteria group .
pij是第i个标准组中第j个标准的优先级的值。
A sequence ( vn , n ≥ 1 ) is called a delayed renewal sequence if and only if it is a transition probability sequence ( pij ( n ), n ≥ 1 ) of a Markov chain for some i and j. In this paper , we prove that the delayed renewal sequence semigroup has property ILID ( that is , an infinitesimal array limit is infinitely devisible ), and that the . semigroup of positive delayed renewal sequences is a Delphic semigroup .
