摘　　要：针对具有时空耦合特性的船舶曲面分段生产调度问题,提出以充分利用场地资源为目标的基于虚拟流水生产方式的空间调度方法,建立了曲面分段生产调度流程。通过分析曲面分段具有不规则外形轮廓、空间和时间双重占用以及虚拟流水生产方式的特点,建立了曲面分段空间调度的总体框架。提出虚拟流水生产方式与空间调度相结合的调度方法,形成了分段生产顺序与空间调度过程相互衔接的机制,解决了曲面分段空间调度过程中分段建造顺序的问题;提出碰撞检测算法与优化规则筛选相结合的曲面分段空间布局方法,解决了不规则轮廓的曲面分段空间排布问题;提出基于虚拟流水生产的人力资源分配方法,实现了资源围绕固定工位的流转生产。通过应用曲面调度实例对以上关键技术进行了验证。Aiming at the ship curve block scheduling problem with spatio-temporal coupling, the spatial scheduling method based on virtual flow style was proposed to make full use of field resources. Through analyzing the curve block features of irregular shape, spatio-temporal dual holding and virtual flow production, the general framework of curve block spatial scheduling was constructed. The scheduling method combined virtual flow style with spatial scheduling was proposed, and the mechanism by linking production order with spatial scheduling was formed, which could solve the production sequence problem. The spatial layout method for curve block was given by combining the collision test with optimal screen was given. The allocation method of human resource based on virtual flow style was obtained to realize workers transfer among dedicated work station. The instance of curve example was developed to illustrate the effectiveness of the proposed approach.
