【摘要】 随着钢铁、煤炭行业经济回暖,A公司承揽重型机械制造订单数量有所回升,且工期要求紧促,由于A公司在以往生产制造过程中,多次因进度管理不善造成拖期,进度管理一直是企业项目实施过程中的难题。面对当前企业生产困境,本文针对重型机械项目提出一种基于关键链技术的进度管理模式。传统进度管理常采用甘特图和关键路径法,没有考虑资源冲突以及人的因素的影响,存在着一定的不足。本文在总结国内外现有进度管理方法和关键链理论研究的基础上,介绍了关键链技术相关概念,阐明关键链方法的内涵,研究关键链项目管理体系和流程,并且分析A公司当前项目管理中进度管理现状和存在的问题,有针对性的建立基于关键链的进度管理体系,包括项目管理计划流程建立以及进度的控制。首先,结合Project工具和活动重心定理确定项目关键链,平衡资源冲突;其后考虑项目资源紧张度,网络复杂度,项目经理风险偏好等影响因素并利用AHP法对不同因素的影响权重进行分析,从而确定项目关键链缓冲区,并利用动态缓冲控制方式,不断调整项目关键链和缓冲区的大小,从而实现对项目进度有效控制。最后本文将进度管理模型应用于A公司的重型机械项目中,验证模型的有效性及可行性。关键链技术应用在重型机械项目中解决了A公司面临的进度难题,能够提高企业的生产效率,缩短项目工期,同时也为其他重型机械企业进度管理提供一定的理论支持和应用借鉴。更多还原

【Abstract】 With the economy recovery of steel and coal industry,the number of heavy-machinery manufacture orders company A achieves is on the increase with tight work schedule.Since poor management of progress schedule during the previous manufacture process leads to the project delivery delay many times for company A,therefore,schedule control has always been a tough problem in the project implementation.This thesis puts forward the optimization for the current schedule control in company A based on critical chain technique.The traditional schedule management methods such as Gantt chart and Critical Path Method,without considering the conflict of resources and the human behavior factors,have certain deficiencies.The thesis,based on summary of the current schedule optimization and critical chain technique theory home and abroad,introduces the relevant concepts of critical chain technique,clarifies the connotation of the critical chain method,and studies the management system and process of critical chain projects.Moreover,it analyses the current management status and problems for company A,and establishes schedule control system based on critical chain,including establishing project management plan process and schedule control.First,identify project critical chain through tool Project and moving gravity theory,and balance resource conflicts.Subsequently,take several factors into consideration,such as project resource shortage,network complexity,project manager risk preference etc,make use of AHP method to analyze the weight of influence for different factors,so as to determine the buffer zone of project critical chain,and take advantage of dynamic buffer control mode to control the project schedule.Finally,apply the schedule control model into heavy-machinery projects in company A to validate the effectiveness and feasibility of the model.The application of critical chain technique in the heavy machinery project solves the schedule problem for company A,improves the production efficiency and shorten the project duration.At the same time,it also provides some theoretical support and application references for schedule management of other heavy machinery enterprises.更多还原
