在本文中，我们提出了一个程序来估计缺失的偏好值时，处理两两比较和异构信息。这个过程试图估计缺失的信息，在一个专家的不完全偏好关系，仅使用的偏好值提供的特定专家。我们估计缺失值的过程可以应用于不完整的模糊，乘法，区间值和语言偏好关系。显然，保持专家的一致性水平是可取的。我们利用加性一致性属性来衡量一致性的水平，并指导过程中的缺失值的估计。最后，给出了不完全偏好关系中所有缺失值的估计的成功条件。(c)2008 Wiley Periodicals，Inc.
In this paper, we present a procedure to estimate missing preference values when dealing with pairwise comparison and heterogeneous information. This procedure attempts to estimate the missing information in an expert's incomplete preference relation using only the preference values provided by that particular expert. Our procedure to estimate missing values can be applied to incomplete fuzzy, multiplicative, interval-valued, and linguistic preference relations. Clearly, it would be desirable to maintain experts' consistency levels. We make use of the additive consistency property to measure the level of consistency and to guide the procedure in the estimation of the missing values. Finally, conditions that guarantee the success of our procedure in the estimation of all the missing values of an incomplete preference relation are given. (c) 2008 Wiley Periodicals, Inc.
