The results implementing Weak Ordinal Relations (WOR) have change for transfering to similar DEA (C 2W)structures, vs.
主要探讨数据包络分析模型中加权系数序关系对ＤＥＡ评价的有效性敏感分析，并给予了Ｃ２Ｗ模型的推导证明，结果表示弱序性不能够保证，对于强序关系进行推广构造决策者偏好结构，发现它具有直观简易的特点，与Ｃ２ＷＨ模型相比，更易于构造偏好结构和权序关系，易于实现决策支持系统，具有实用价
This paper proves that a weakly-sequential space X with a σ-weakly hereditarily closure-preserving sn-network has a σ-compact finite sn-network.
文中证明了一个具有σ-弱遗传闭包保持sn-网的弱序列空间具有-σ紧有限sn-网。
In this paper, we define the concept of weak order-Lipschitz condition, and study the existence of fixed point of some concave (convex) operators without continuity and compactness conditions in Banach spaces.
引入弱序Lipschitz条件,研究了Banach空间中不具有任何紧性或连续性条件的一类凹(凸)算子不动点的存在性, 得到了新的不动点定理,是某些已有结果的本质改进和推广。
Provides the conditions for the monotonicity of a sort of Banach lattice space norm and its local uniform monotonicity and further proves that the space is the sufficient and necessary condition for the completion of the weak sequence.
给出了一类 Banach格空间范数的单调性及局部一致单调性的条件 ,进一步得到了该空间是弱序列完备的充要条件。
