In this paper, we mainly study extensions of partial order and finitely totally order for partially ordered semirings, and obtain some new results. 本文主要研究了偏序半环的偏序扩张和有限全序扩张，并得到了一些新的结果。
A new aggregating method was presented for ranking alternatives based on partial order preference of groups about each criterion, and decision maker without determining weights. 针对决策者给出方案集在每个属性下的偏序偏好，且决策者没有确定权重的多属性群决策问题提出了一种新的集结排列方法。
