【摘要】：随着城市化和钢结构建筑的推广，催生了全国各地钢结构制造企业的快速发展，钢结构制造企业的良好发展对国民经济建设具有重要的现实和历史意义。钢结构制造企业是典型的面向订单设计型企业，其生产为项目型制造，具有订单随机性、客户高度定制、生产一次性、制造周期长、产品体量大类型复杂、多项目同时运作、生产环境不确定因素多等特点。企业传统的管理方式尤其计划管理方式，如单项目管理、关键路径法、计划评审技术，已不能满足企业的现实需求，常常出现资源冲突、计划协调和执行差、人为影响、交货期延迟等情况。因此，本文基于对钢结构制造企业特点和需求的理解，研究并提出了钢结构制造企业的关键链多项目计划管理体系、生产计划与进度控制方法，具有一定的理论与实践意义。首先，本文在总结国内外已有关键链理论研究的基础上，介绍了钢结构制造企业生产与产品特点、资源特点以及多项目管理特点，分析了多项目管理现状及问题，，指出了关键链解决这些问题的优势，探讨了钢结构企业推行关键链多项目管理的必要性。其次，在研究推式和拉式计划相结合，关键链思想与最后计划者体系相结合的基础上，建立了关键链多项目计划管理体系。并设计了关键链多项目管理组织结构及流程，以满足和配合关键链多项目计划管理体系的要求。再次，重点从生产计划制定、进度控制两方面研究了钢结构制造企业生产计划与控制管理。论文提出了基于关键链的生产计划制定与优化过程，包括项目优先权评定、产品流程建立、关键链调度项目、鼓资源配置与协调、关键材料和门的设置；在生产进度控制方面，构建了关键链缓冲进度控制机制。最后，将研究结果应用到一家钢结构制造企业中，就本文所提出的方法进行了实证分析。具体分析了公司多项目管理存在的问题，以此为导向，改善了公司组织结构，并以实例说明了关键链多项目生产与控制方法的应用过程。
[Abstract]:Along with the urbanization and the promotion of steel structure building, the rapid development of steel structure manufacturing enterprises in all parts of the country has been spawned. The good development of steel structure manufacturing enterprises has important realistic and historical significance for the national economic construction. Steel structure manufacturing enterprise is a typical order-oriented design enterprise, its production is project-based manufacturing, with order randomness, customer highly customized, one-off production, long manufacturing cycle, product volume large type complex, multi-project operation at the same time. There are many uncertain factors in the production environment. The traditional management methods of enterprises, such as single project management, critical path method and plan review technology, can not meet the actual needs of enterprises, and there are often resource conflicts, poor plan coordination and execution, and artificial influence. Delay in delivery, etc. Therefore, based on the understanding of the characteristics and requirements of steel structure manufacturing enterprises, this paper studies and puts forward the key chain multi-project planning management system, production planning and schedule control methods of steel structure manufacturing enterprises, which has certain theoretical and practical significance. First of all, on the basis of summarizing the research of key chain theory at home and abroad, this paper introduces the production and product characteristics, resource characteristics and multi-project management characteristics of steel structure manufacturing enterprises, and analyzes the current situation and problems of multi-project management. This paper points out the advantages of key chain to solve these problems, and probes into the necessity of carrying out multi-project management of key chain in steel structure enterprises. Secondly, based on the research on the combination of push and pull planning, the key chain idea and the final planner system, a key chain multi-project planning management system is established. The organization structure and process of key chain multi-project management are designed to meet and cooperate with the requirements of key chain multi-project planning management system. Thirdly, the production planning and control management of steel structure manufacturing enterprises are studied in terms of production planning and schedule control. The paper puts forward the production planning and optimization process based on key chain, including project priority evaluation, product flow establishment, key chain scheduling project, drum resource allocation and coordination, key material and door setting, production schedule control. The key chain buffer schedule control mechanism is constructed. Finally, the research results are applied to a steel structure manufacturing enterprise, and the method proposed in this paper is analyzed empirically. This paper analyzes the problems existing in the multi-project management of the company, improves the organizational structure of the company, and illustrates the application process of the key chain multi-project production and control method with an example.
