港口装卸机械的综合评价

The Comprehensive Appraisal of Port Handling Mechanical Equipments

根据港口装卸机械的主要技术经济指标,以某港的27台叉车为例,首先用聚类分析进行分类,然后用判别分析进行判别。利用这种方法,可以对长期以来不能综合评价的具有不同量纲、不同数量级的多项指标的港机进行评定。

According to the main technical and economic indicators of port handling mechanical e- quipments, taking the 27 units from those forklifts in a certain port as an example, firstly this paper employs the cluster analysing method to determinate the classes of the samples. Then it adopts discriminant analysing method to discern them. This method is comprehensively able to compare and appraise the loading-unloading machine's muti-indicators with different dimen- sions, which has not been done for a long time until now.
