【摘要】：我国海军舰船及其相关设备制造属于项目型制造,具有质量要求高、品种多和交货周期短等特点,各设备厂商都面临着要在更短的时间内生产出更高质量标准的产品,对此类产品的生产进度管理提出了挑战。实际调研表明:60%以上的舰船及其相关设备制造存在拖期,需通过频繁的加班进行调整。导致产品的制造成本较高、质量管理和产品制造的项目进度管理难度较大,迫切需要开展海军舰船及其相关设备制造的项目进度管理方法研究,以提高准时交货率、降低制造成本。本文分析了某设备制造企业项目进度管理现状,以某船主推进监控系统装配项目为研究对象,收集、分析了该产品的装配任务分类、工时、装配资源和装配顺序。分析了装配过程中设计更改、制造资源效率低,生产进度安排不合理和缺乏信息系统支持等原因导致的项目拖期。然后,论文构建了基于关键链进度管理体系,识别某主推进监控系统装配过程中的关键链,设置缓冲区,并应用于实际生产。有效提高了资源利用率和产品准时交货率。在此基础上,分析产品项目进度管理软件的需求,设计了软件的流程、数据库和界面,开发了基于关键链法的项目进度计划管理软件,包括交货期汇总,项目进度汇总,工时表和装配进度甘特图等功能模块,支持相关部门人员的进度查询、调整和执行。实践表明:关键链法与管理软件相结合,能有效提高某船主推进监控系统装配项目的准时交货率,减少因拖期、计划调整导致的资源浪费,从而有效减低制造成本。
[Abstract]:The manufacture of naval vessels and related equipment in our country belongs to project-based manufacturing, which has the characteristics of high quality requirements, variety and short delivery period. All equipment manufacturers are faced with the need to produce products of higher quality standards in a shorter time. The management of production schedule of this kind of products is challenged. The actual investigation shows that more than 60% of ships and their related equipment manufacturing have a delay period, which need to be adjusted through frequent overtime. As a result of the high manufacturing cost of products and the difficulty of quality management and project schedule management in product manufacturing, it is urgent to study the project schedule management methods for naval ships and their related equipment in order to improve the on-time delivery rate. Reduce manufacturing costs. This paper analyzes the status quo of project schedule management in a certain equipment manufacturing enterprise, taking the assembly project of a ship owner's propulsion monitoring system as the research object, collecting and analyzing the assembly task classification, working hours, assembly resources and assembly sequence of the product. This paper analyzes the project delay caused by the design change in the assembly process, the low efficiency of manufacturing resources, the unreasonable production schedule and the lack of information system support. Then, based on the key chain schedule management system, the paper identifies the key chain in the assembly process of a certain main propulsion monitoring system, sets up a buffer zone, and applies it to practical production. The utility ratio of resources and the delivery rate of products on time are improved effectively. On this basis, the requirements of product project schedule management software are analyzed, and the software flow, database and interface are designed, and the project schedule management software based on key chain method is developed, including due date summary, project schedule summary, and so on. Function modules such as man-hour table and assembly schedule Gantt chart to support progress query, adjustment and execution of relevant department personnel. The practice shows that the combination of the key chain method and the management software can effectively improve the on-time delivery rate of the assembly project of the ship owner's propulsion monitoring system, reduce the waste of resources caused by the delay and the planned adjustment, and thus effectively reduce the manufacturing cost.
