针对封闭式行星传动卷筒整体参数，建立了以体积最小、可靠度最高、传动效率最高为分目标的模糊多目标优化模型。提出了一种新的模糊判决解法。该解法采用非对称模型思想，而模糊判决集则采用加权型模型的形式。实例表明这种解法所得优化结果，更接近工程实际。
According to the overall parameters of the closed planetary drive roll, a fuzzy multi-objective optimization model is established with the smallest volume, the highest reliability and the highest transmission efficiency. A new fuzzy decision method is proposed. The solution uses the idea of asymmetric models, while the fuzzy decision sets take the form of weighted models. The example shows that the optimal result of this solution is closer to the actual project.
