【摘要】：近年来我国船舶制造业取得了长足进步，但造船管理水平低一直以来制约其进一步发展，而敏捷造船又对我国船舶制造业的管理水平提出了更高的要求，因此，，如何提高船舶敏捷制造项目管理水平就显得尤为重要。进度管理是船舶制造项目管理中最重要的内容之一，本文针对我国船舶敏捷制造项目进度管理落后的现状，分析传统项目进度管理方法在船舶敏捷制造项目管理中的不足，提出利用系统动力学来研究船舶敏捷制造项目进度管理。通过介绍系统动力学的基本原理与船舶敏捷制造项目的特点，得出利用系统动力学研究我国船舶敏捷制造项目进度管理的可行性与优越性。详细分析了现代船舶敏捷制造项目的进度管理过程，界定了影响船舶制造进度的主要因素，利用系统动力学分析了各因素之间的相互影响关系及其组成的多条反馈回路，得到了船舶敏捷制造项目进度管理系统的因果回路图，在此基础上进一步挖掘系统变量，确定各变量之间的数量关系，最终建立了我国船舶敏捷制造项目进度管理的系统动力学模型。为了提高模型的实用性，满足船舶制造过程中制造任务之间的前后逻辑关系及各种资源约束，本文借鉴关键链的思想，提出了一种船舶生产任务排序的启发式算法，并通过相关变量将其融入到系统动力学模型中，通过算例分析，证明关键链思想的引入可以使模型更符合实际。最后，论文基于一个实际的船舶制造项目，利用Vensim仿真软件对所建立的系统动力学模型进行了相关模拟仿真。首先通过与关键路径法的对比，证明模型在船舶敏捷制造项目进度计划的制定方面更准确，然后通过各种进度控制策略的仿真实验，证明模型可以向船舶敏捷制造项目进度管理者提供各种有效的进度控制策略信息，帮助其快速而准确地制定合理而有效的进度控制措施，实现对船舶敏捷制造项目进度的动态控制，这对我国船舶敏捷制造项目进度管理水平的提升有一定帮助。
[Abstract]:In recent years, China's shipbuilding industry has made great progress, but the low level of shipbuilding management has been restricting its further development, and agile shipbuilding has put forward higher requirements for the management level of our shipbuilding industry. How to improve the management level of ship agile manufacturing project is particularly important. Schedule management is one of the most important contents in ship manufacturing project management. This paper analyzes the shortcomings of traditional project schedule management methods in ship agile manufacturing project management, and proposes to use system dynamics to study ship agile manufacturing project schedule management. This paper introduces the basic principles of system dynamics and the characteristics of ship agile manufacturing project. The feasibility and superiority of using system dynamics to study the schedule management of ship agile manufacturing project in China are obtained. The progress management process of modern ship agile manufacturing project is analyzed in detail, and the main factors influencing the progress of ship manufacturing are defined. Based on the system dynamics analysis of the interaction between various factors and the composition of multiple feedback loops, the causality loop diagram of the ship agile manufacturing project schedule management system is obtained, and the system variables are further excavated. Finally, the system dynamics model of schedule management of ship agile manufacturing project in China is established. In order to improve the practicability of the model and to satisfy the logical relationship between manufacturing tasks and various resource constraints in the shipbuilding process, a heuristic algorithm for scheduling ship production tasks is proposed in this paper, using the idea of key chain for reference. The model is integrated into the system dynamics model by the related variables, and it is proved by the example analysis that the introduction of the key chain can make the model more practical. Finally, based on an actual ship manufacturing project, the system dynamics model is simulated by using Vensim software. Firstly, it is compared with the critical path method. It is proved that the model is more accurate in making the schedule of the ship agile manufacturing project, and then the simulation experiment of various schedule control strategies is carried out. It is proved that the model can provide all kinds of effective schedule control strategy information to ship agile manufacturing project schedule managers and help them to formulate reasonable and effective schedule control measures quickly and accurately. The dynamic control of the progress of ship agile manufacturing project is realized, which is helpful to improve the management level of ship agile manufacturing project in our country.
