【摘要】：生产计划管理是船厂生产管理的核心,它为船厂组织生产活动提供目标、指标、实施步骤和预期成果估计。现有船舶生产计划管理粗放,计划管理工具落后,计划指导下的生产过程负荷不均衡和连续性差,使得实际生产过程中存在大量的生产浪费,最终导致船舶生产效率低下,造船周期和生产成本难以控制。精益造船正是以消除船舶生产过程中的各种浪费为主要目标的生产模式。因此,以精益造船思想来指导计划制定、调整以及执行控制,即推行精益船舶生产计划管理,从计划层面消除生产过程中的各种浪费,可有效提高船厂的生产效率和经济效益。本文从现有船舶生产计划管理过程中存在的问题出发,结合精益船舶生产计划管理流程及特征,构建精益船舶生产计划优化模型,实现计划编制与调整的智能化高效化,使得计划能够体现消除浪费、均衡连续以及需求拉动等精益思想。同时,开展生产计划管理系统功能分析研究与开发。详细内容如下:1)分析船舶生产计划管理过程中存在的问题,结合精益造船理念和主要内容,构建精益船舶生产计划管理流程,并研究与分析精益船舶生产计划管理过程中的生产任务分解结构和计划特征。2)针对精益船舶生产计划管理对计划调整的功能需求,本文从精益船坞搭载计划优化、精益先行中日程计划优化、精益后行中日程计划优化及精益先行加工中日程计划优化4个方面构建精益船舶生产计划优化模型。3)针对计划优化模型变量离散和非线性问题,提出以改进的粒子群算法为核心的精益生产计划优化模型求解流程,以实际船厂生产计划优化问题为例,对比分析优化前后生产计划的性能来验证模型的高效性。结果表明,优化后生产计划可行性更好,生产负荷更均衡,资源利用率更高。4)利用UML处理复杂系统的优势,进行精益船舶生产计划系统的分析与设计。初步实现系统功能,开发系统界面,实例验证系统运行状况和流程。
[Abstract]:Production planning management is the core of the production management of the shipyard. It provides targets, indicators, implementation steps and expected results for the production activities of the shipyard. The existing ship production plan management, plan management tools behind, plan under the guidance of the production process of load imbalance and poor continuity, the existence of a large number of production waste in the actual production process, resulting in low efficiency of ship production, shipbuilding cycle and production cost is difficult to control. Lean shipbuilding is the production model which aims at eliminating all kinds of waste in the process of ship production. Therefore, guided by lean shipbuilding idea, we should guide the formulation, adjustment and implementation control of the plan, that is, to implement lean ship production plan management and eliminate all kinds of waste in the production process from the planning level, we can effectively improve the production efficiency and economic efficiency of the shipyard. This article is from the existing ship production plan management process, combined with lean ship production plan management process and characteristics, construct the production plan optimization model of lean ship, intelligent planning and adjustment of the plan can reflect the high efficiency, eliminate waste, continuous and balanced demand and lean thinking. At the same time, we carry out the research and development of the function analysis of the production planning management system. The detailed contents are as follows: 1) analysis of the existing ship production plan management process, combined with lean shipbuilding concept and main content of construction of lean ship production plan management process, and the process of research and analysis of lean production plan management in ship production task decomposition structure and plan features. 2) functional requirements for lean production planning and management of ship plan adjustment, this paper from the lean dock equipped with plan optimization, schedule optimization, in advance of lean lean leap in plan optimization and schedule ahead of schedule in the process of Lean Construction Optimization optimization lean ship production plan model 4 aspects. 3) according to the plan optimization model with discrete variables and nonlinear problems, puts forward the optimization plan for lean production process model based on improved particle swarm algorithm as the core, to the actual shipyard production plan optimization problems for example, efficiency comparative analysis of performance before and after optimization of production plan to validate the model. The results show that the optimized production plan is better, the production load is more balanced and the utilization of resources is higher. 4) the analysis and design of lean ship production planning system are carried out by using the advantages of UML to deal with complex systems. The system function is realized preliminarily, the system interface is developed, and the instance verifies the running status and process of the system.
