vague集本质上是一种含有不确定性的模糊集，应用时需要做不确定性分析。为此，把集对分析联系数应用于黑启动vague集决策之中。首先，把用vague集表示的专家权重、指标权重与指标值都改写成联系数的形式，得出基于联系数的黑启动vague集决策模型，再对模型的计算结果作不确定性分析，考察不确定性条件下的各方案排序变化，选出最优方案。实例应用表明，文中所提方法能有效解决用vague 集表示的评价指标之间存在关联性和不确定性的黑启动多方案选优问题，思路清晰，算法简明，便于现场决策应用。
vague集本質上是一種含有不確定性的模糊集，應用時需要做不確定性分析。為此，把集對分析聯繫數應用于黑啟動vague集決策之中。首先，把用vague集錶示的專傢權重、指標權重與指標值都改寫成聯繫數的形式，得齣基于聯繫數的黑啟動vague集決策模型，再對模型的計算結果作不確定性分析，攷察不確定性條件下的各方案排序變化，選齣最優方案。實例應用錶明，文中所提方法能有效解決用vague 集錶示的評價指標之間存在關聯性和不確定性的黑啟動多方案選優問題，思路清晰，算法簡明，便于現場決策應用。

A vague set is a kind of fuzzy set that contains uncertainty.So uncertainty analysis is required in the ap-plication of it.To solve this problem,the proposed decision-making method of a black-start vague set is based on connection number analysis of set -pair.First, rewrite the expert weights, index weights and targeted values repre-sented by vague sets into the connection number form.Next, obtain the decision model of a vague set for black-start based on connection number, analyze the uncertainty of the model calculations, study the changes in the ranking of each project in conditions of uncertainty and select the optimal project.Practical application shows that the method can deal with the problem of optimizing black-start schemes of the correlation and uncertainty in the selected evalu-ation indexes effectively and clearly.It is simple in algorithm and convenient to make decision on spot.
