基于多移动智能体的港口混杂超网络抗毁性拓扑重构方法研究

In Port Internet of Things (PIoT), due to its features of heterogeneous-super network and its performance vulnerable to deployment scenarios and practical production, poor invulnerability has already become the one of its major technical bottlenecks. Therefore, this project plans to carry on research on the key scientific issue "topology reconstruction of heterogeneous super network" on the background of PIoT. Firstly, the project attempts to propose a heterogeneous super network model for PIoT considering parallel and hierarchy coupling relationships and constraints of practical production, so as to describle the heterogeneous characteristics and the multi-dimentional super network behavior; Secondly, analyze the dynamic evolution law of the PIoT activated by cascading events, so as to reveal its failure mechanism; Thirdly, select smart production resources as control objects and design a network topology reconstruction method based on multi-mobile agents in order to enhance the network invulnerability while maintaining a high level of the production quality. This project can provide theoretical and technical supports for invulnerability optimization of super network from the perspective of system modelling and optimization. In addition, it can also provide the technical guidance for the construction and upgrade of smart port.

港口物联网因具备典型混杂超网络特征且性能易受部署环境与生产作业影响，抗毁性不足是其所面临的主要瓶颈问题。为此，本项目以港口物联网等复杂耦合网络系统为对象，围绕“混杂超网络抗毁性拓扑重构”这一共性关键科学问题开展研究。首先，项目通过子网拓扑结构提取与耦合关系分析，构建生产约束条件下具有相交-层间耦合特征的港口混杂超网络模型，用于描述港口物联网混杂特性与多尺度（个体-子网-系统）超网络行为；然后，基于级联事件激励，分析网络动态演化规律，揭示港口混杂超网络失效机理；最后，以智能生产资源为控制对象，设计基于多移动智能体的网络拓扑博弈重构算法，在确保生产服务质量的前提下，提升港口物联网抗毁性能。项目的实施及其成果从系统建模与网络优化角度，将进一步丰富超网络抗毁性优化相关理论，并为智能港口建设与升级改造提供技术支撑。

在以工业物联网与港口物联网等为代表的面向实际生产运作的物联网系统中，物联网节点作为参与生产的智能生产要素，除感知与传递信息外，还需根据其所承担的生产任务输出相应服务。在制造流程、工序和物料供给等多个因素的影响下，物联网节点所输出的服务彼此密切相关。物联网节点所扮演的双重角色（消息发送者与服务参与者）的双重角色促使上述面向实际生产的物联网系统呈现出典型的具有信息-服务耦合结构的混杂超网络特征。这种紧密的耦合关系在使系统能够更灵活、更智能地完成生产任务的同时，也会导致整个生产系统从网络角度变得更加脆弱。为此，本课题以工业物联网与港口物联网等实际生产网络系统为对象，围绕“混杂物联超网络抗毁性优化”这一共性关键科学问题开展研究，形成了包括混杂超网络建模与演化分析技术、物联网级联失效抗毁性优化技术、混杂超网络拓扑重构技术、物联网多径抗毁路由技术等在内的一系列成果，并构建原型测试系统用于验证模型与算法有效性。本课题执行期间取得了良好的进展，形成了一系列研究成果，并发表于知名国际学术期刊及会议。
