【摘要】 Z公司是我国重型装备制造行业的一家知名企业,是全世界最大的港口机械重型装备制造商。但随着这些年港口集装箱起重机市场份额的不断扩大,不断吸引着诸多制造业企业进入或重返这一领域,导致行业竞争异常激烈。与这些竞争企业相比,Z公司虽然具有一定的竞争优势,但由于企业生产线长期满负荷运作,企业生产存在一定程度的重生产,轻管理的一种倾向,导致企业在生产管理的一些方面,例如公司在起重机电气调试进度管理领域,还需要进一步完善。电气调试进度是否能顺利按照计划节点完成,是整个起重机制造过程中的一个至关重要的验收节点。通过优化Z公司在起重机电气调试过程中的生产管理,从而充分发挥企业在同质化竞争中的潜在优势,已经成为Z企业能够在行业中继续保持领先的源动力。本文运用现代项目管理理论,对Z公司在岸边集装箱起重机生产过程中的调试进度计划编制和调试进度控制进行了研究。首先介绍了Z公司的行业背景以及起重机的电气调试流程。之后,分析了Z公司在电气调试计划及进度管理的现状以及存在的问题,得出公司各级管理架构有待进一步优化,项目调试范围定义不明晰,存在项目蔓延,项目调试的活动顺序排布不合理,活动分解不够细化,调试过程中活动资源分配不合理,调试进度反馈机制滞后等问题。再后,根据Z公司实际的生产特性,设计了起重机电气调试项目进度的优化方案,通过对调试活动进行进一步的WBS分解、重新优化排布各任务活动顺序,合理估算各任务活动时间,从而重新分配项目总体缓冲,并基于关键链技术编制项目调试进度计划;采用关键链缓冲区动态控制原理,具体通过采取项目实际进度和计划进度之间数据对比的方式得出结论,并及时运用项目进度压缩技术,对调试进度进行动态实时纠偏,可以在时效性和精准性两方面确保对项目调试进度的控制。然后,通过Z公司加拿大GCT码头起重机的电气调试项目计划及进度管理优化的实例进行评估,评估结果为,该优化方案对于完善起重机电气调试计划编制,提高调试资源的利用率,以及实时控制起重机电气调试进度,降低项目的调试进度延误发挥了很好的效果。最后,提出了本文的总结和展望。本论文通过对起重机电气调试项目进度管理优化的研究,不仅提高了Z公司集装箱起重机生产的绩效,又预防和降低了电气调试过程中的延误风险,保证了产品的及时交付,对于Z公司今后在电气调试领域的生产进度控制有着很好的借鉴意义。更多还原

【Abstract】 Z company is a very famous company in China’s quay crane equipment manufacturing industry.It is the largest port machinery manufacturer in the world.However,with the continuous expansion of the market share of port container crane in recent years,many manufacturing enterprises have been attracted to enter or return to this field,resulting in fierce competition in the industry.Compared with the competitive enterprise,Z company although has certain competitive advantage,but because the enterprise production line full load operation for a long time,have a certain degree of enterprise production production,a tendency of light management,lead to some of the aspects of the enterprise in production management,such as crane electrical commissioning schedule management,also has further optimization of the space.Whether the electrical debugging schedule can be successfully completed according to the planned node is a crucial acceptance node in the whole crane manufacturing process.How to optimize the production management of Z company in the process of crane electrical debugging,has become the key factor and urgent requirement for Z company to remain unbeat in the industry in the future.In this paper,the author using the modern management methods to make the research.Firstly,introduce the Z Company and the electrical commissioning process of the quayside container crane.Secondly,the paper analy Zes the present situation and existing problems of Z company in the field of electrical commissioning plan and schedule management,which concluded that the managing structure of the company need to be improved.Also exists some problems of project spread,unreasonable activity sequence arrangement of project commissioning,insufficiently detailed activity decomposition,unreasonable activity resource allocation in commissioning process,and lack of closed loop control of commissioning schedule.Thirdly,through the design of optimi Zation scheme for Z Company’s crane electrical commissioning project schedule,using a number of project schedule management tools and methods,through further WBS decomposition of commissioning activities,re-optimi Zing the sequence of tasks and activities,reasonably estimating the time of each task and setting buffer,by using the critical chain buffer dynamic control theory,we could compare the actual project processing based on the project plan,by using the project schedule compression technology,the real-time dynamic correction of the project commissioning schedule can effectively ensure the timeliness and precision of the project commissioning schedule control.Then,through Z company’s Canada GCT wharf crane project as example,be used for evaluating the optimization of the project planning and commissioning management.After the evaluation,the result is,the optimized scheme has played a very good effect in many aspects as for perfecting the crane electrical commissioning plan,improve resource utili Zation,and real-time control crane electrical commissioning progress,reduce project commissioning progress delay.In this paper,by means of researching the optimi Zation of crane’s electrical commissioning,not only improve the performance of Z company container crane production,but also prevent and reduce the delay risks in the process of commissioning,could ensure the timely delivery of products.That research has a very good reference significance for Z company in the field of electrical commissioning production progress control in the future.更多还原
