【摘要】：管舾件生产作为船舶舾装作业的核心,其生产计划情况,直接影响着全船建造的进度和安排。管件族制造法,在管加工过程中利用部件的相似性,将单件式的管子按照批量生产方式来组织生产,可以降低生产和管理成本,提高产量和设备利用率。由于,船舶制造属于MTO生产方式,船舶管件品种多样,加工工艺因规格和形状的不同而变化,因而实现批量加工的管舾件生产计划与控制比较困难。因此,本文在船舶管舾件加工双托盘管理的基础上,提出了管舾件批量加工生产计划与控制方法。首先,本文针对船舶管件及其加工工艺的特点,设计面向双托盘管理的生产计划与控制体系,将船舶管舾件加工生产计划化分为三个层次:安装托盘计划、制造托盘计划、加工任务计划与控制。其次,在安装托盘计划中,托盘的生产排程不仅决定了托盘的交货时间,也影响着管件族制造法的成组效率,因此,考虑安装托盘两两之间的准备时间,建立安装托盘生产排程模型。第三,在制造托盘计划中,为了实现管件族制造法,对安装托盘中的管件按照管径和连接件类型划分管件族。并对生产线加工负荷平衡问题,构建管件族加工负荷分配模型,使各条生产线的负荷限额比尽量相等。第四,在加工任务计划与控制中,为了减少加工提前期和搬运成本,针对管件族批量加工过程,应用排队理论,构建管舾件加工批量优化决策模型,适用于单台设备和并联设备加工系统。设计管件加工双环PFB控制模式,实现对生产线物料投放的控制。最后,将CD船厂安装托盘实例,应用到管件族加工负荷分配模型和管舾件加工批量优化决策模型。验证了管件批量加工生产计划与控制方法的可行性和有效性。
[Abstract]:Pipe outfitting production as the core of ship outfitting operation, its production planning directly affects the progress and arrangement of the whole ship construction. The production of single-piece pipes can be organized according to the mass production mode, which can reduce the production and management cost, improve the output and equipment utilization ratio. Because the shipbuilding belongs to the MTO mode of production, the variety of ship pipe fittings is various. Due to different specifications and shapes, it is difficult to plan and control the production of pipe outfitting and outfitting parts in batch processing. Therefore, this paper is based on the management of double pallets for ship pipe fitting and fitting parts. The production planning and control method of pipe outfitting parts is put forward. Firstly, according to the characteristics of ship pipe fittings and their processing technology, the production planning and control system oriented to the management of double pallets is designed in this paper. The ship pipe outfitting parts production planning can be divided into three levels: the installation pallet plan, the manufacturing pallet plan, the processing task plan and control. Secondly, in the installation pallet plan. The production scheduling of pallets not only determines the delivery time of pallets, but also affects the group efficiency of tube-family manufacturing methods. Therefore, the preparation time between pairings of pallets is considered. Set up the production scheduling model of installation pallet. Third, in order to realize the pipe family manufacturing method in the manufacturing pallet plan. The pipe fittings in the installation tray are divided into tubing families according to the pipe diameter and the type of fittings, and the load distribution model of the pipe family is constructed to balance the processing load of the production line. The load limit ratio of each production line is as equal as possible. 4th. In order to reduce the processing lead time and the handling cost, the queuing theory is applied to the batch processing process of the pipe family in the process planning and control of the processing task. Set up the batch optimization decision model of pipe fitting parts processing, which is suitable for single equipment and parallel equipment processing system. Design the double loop PFB control mode for pipe fittings processing, realize the control of production line material delivery. Finally. The example of CD shipyard installation tray is applied to the pipe family load distribution model and the batch optimization decision model of pipe outfitting parts. The feasibility and effectiveness of the production planning and control method for pipe fittings batch processing are verified.
