| 摘 要： | 船舶动力设备拆装是船员适任证书考试的重要环节,为对该考试过程进行智能化评估,将船舶动力设备拆装过程抽象为以拆装任务为节点、任务之间联系为边的复杂网络。从网络整体结构特征和局部特征两个方面对网络复杂性进行分析;通过测量网络节点中心性指标对设备拆装关键任务进行识别;通过计算网络最短路径进行任务相关性分析,确定设备拆装的步骤。以船用6135柴油机吊缸拆卸过程为例,验证了模型的有效性。本文提出的方法还可为其他机械设备的拆装和维修过程提供参考。

| Abstract: | The disassembly and assembly of marine power equipments is an important link in the certificate examination of competency for seafarers. In order to evaluate the examination process intelligently, the process of disassembly and assembly of marine power equipments is abstracted into a complex network composed of nodes denoting tasks and connecting lines between tasks. The network complexity is analyzed from the overall structure characteristics and the local characteristics of the network. The key tasks are identified by measuring centrality indices of the network nodes. The task correlation is analyzed by calculating the network shortest path, and the process of equipment disassembly and assembly is determined. Taking the process of disassembly of the marine 6135 diesel engine cylinder as an example, the validity of the model is verified. The proposed method can provide reference for the disassembly, assembly and maintenance process of other mechanical equipments. |
