面向船体分段生产调度的知识导航系统设计

Design of ship-block production scheduling oriented knowledge navigation system

为了解决船体生产调度任务决策过程中容易迷失方向,效率低下的状况,紧密结合生产调度的领域特性,研究了知识地图以及生产调度相关原理,确立了基于知识地图的船体分段生产调度知识导航体系结构,并分析了其实现的关键技术为面向船体分段生产调度的本体、语义节点的构建集成技术、基于本体的语义关联和知识地图实现技术等,将知识导航系统应用于船体生产调度领域。最后,针对某船厂曲面车间的船体分段调度派工过程,构建了知识导航原型系统实例来进行说明。

A knowledge map based knowledge navigation system model is established by combining the domain characteristics of production scheduling to counter the schedulers＇ low-efficiency on account of confusion during production scheduling process. Key technology points,i, e. knowledge ontology building, semantic node integration, ontology based semantic relevance and the map implementation technique are analyzed. The knowledge navigation system is applied to ship-block production scheduling decision-making process. The method and technologies are verified in the ship-block scheduling process of a workshop in a shipbuilding factory.
