Table 4 The probability thresholds and three?way decisions of three companies using the proposed method

$O$	$o_{1}$	$o_{2}$	$o_{3}$
$P r (C \|[o_{i}])$	0.7035	0.6535	0.3545
${\overset{?}{α}}_{i}^{o p t}$	0.5	0.75	0.6667
${\overset{?}{β}}_{i}^{o p t}$	0.4	0.2857	0.6667
决策模式	三支决策	三支决策	二支决策
决策规则	$P O S (C)$	$B N D (C)$	$N E G (C)$
