【摘要】：伴随着世界经济的飞速发展,市场竞争变得异常激烈。为了公司的财务收入和战略发展,众多企业家们都不断开始考虑同时兼管多个工程项目的问题,多项目管理也随着人们的关注,逐渐成为项目管理届的焦点。同一时间对多个工程项目进行组织管理,虽然各子工程项目间彼此相互独立,但是却需要对企业仅有的有限资源进行合作共享。在对多项目进行组织管理的过程中,极有可能会牵涉到多个工程项目在资金划拨、时间冲突、人才争夺以及设备不足等多种多样的资源冲突和调配共享问题。组织进行多项目管理的核心思想和重点内容就是对资源合理有效的分配,从而使项目施工总工期被缩短、投资成本被降低,最后实现公司整体利益能够得以最大化的目标。关键链技术是一门对项目进行更好管理的新技术,在管理项目时,能发挥出合理缩减工期、协调分配冲突资源,并建立有效缓冲机制来抵抗项目计划实施中的各种不确定因素。所以,在多个工程项目进度管理应用领域,开展关键链技术的研究,有着重大的理论研究和实际指导意义。本文从多工程项目实施协同管理的实际问题着手,以在多项目进度管理执行过程中,能够高效应用关键链方法为主要内容。首先,从企业整体利益角度出发,综合考虑影响多工程项目管理的复杂度和管理实施过程中的各种风险因素,构建能够衡量各项目对于企业整体利益重要性大小的综合评价指标体系,充分结合物元可拓理论的评价思想,建立适合多项目优先级的综合评价模型,有效地将影响因素的“质”和“量”结合在一起,通过构造关联函数计算影响指标的综合关联度,客观得到各个子项目对于企业整体利益的重要性级别;其次,根据关键链方法基本指导思想,结合多工程项目协同管理的实际特点,寻找出影响其进度实施的瓶颈约束资源,并对多项目整体管理计划进行关键链识别,同时依据项目重要性和工序重要性大小,挖掘多项目中瓶颈资源的使用规则,平衡协调瓶颈资源在各项目间引起的资源冲突,得到多项目管理的初步关键链;再次,充分考虑多项目管理中的工序位置和工序复杂度等影响因素,制定适合多项目关键链管理的缓冲区设置新方法,合理消除安全时间并设置缓冲区,确定多项目管理的最终关键链;最后,通过对具体工程实例实施基于多项目优先级的关键链管理计划,证明了该管理模型在多项目进度实施协同管理中的易操作性和科学性,为企业发展实施整体利益最大化管理提供一个新方法。
[Abstract]:With the rapid development of the world economy, the market competition becomes extremely fierce. For the financial revenue and strategic development of the company, many entrepreneurs are constantly beginning to consider the problem of managing multiple projects at the same time. With the attention of people, multi-project management has gradually become the focus of project management. Several engineering projects are organized and managed at the same time. Although each sub-project is independent of each other, it is necessary to cooperate and share only limited resources of the enterprise. In the process of organizing and managing multi-projects, it is very likely to involve a variety of resource conflicts and allocation and sharing problems such as fund allocation, time conflict, talent competition and lack of equipment. The core idea and key content of multi-project management is to allocate the resources reasonably and effectively, so that the total construction period of the project is shortened, the investment cost is reduced, and the goal of maximizing the overall interests of the company is finally realized. The key chain technology is a new technology for better management of the project. In the management of the project, it can play a reasonable role in reducing the duration of the project, coordinating the allocation of conflict resources, and establishing an effective buffer mechanism to resist all kinds of uncertain factors in the implementation of the project plan. Therefore, it is of great theoretical and practical significance to carry out research on key chain technology in many engineering project schedule management application fields. This paper starts with the practical problems of collaborative management of multi-project projects and takes the key chain method as the main content in the implementation of multi-project schedule management. First of all, considering the complexity of multi-project management and various risk factors in the process of implementation, we consider the complexity of multi-project management from the perspective of the overall interests of the enterprise. A comprehensive evaluation index system, which can measure the importance of each project to the overall interests of the enterprise, is constructed, and a comprehensive evaluation model suitable for the priority of multiple projects is set up, which is fully combined with the evaluation idea of matter-element extension theory. Combining the "quality" and "quantity" of the influencing factors effectively, and calculating the comprehensive correlation degree of the influence index by constructing the correlation function, the importance level of each sub-project for the overall benefit of the enterprise is obtained objectively. Secondly, according to the basic guiding ideology of the key chain method, combined with the actual characteristics of multi-project collaborative management, the bottleneck constraint resources that affect the progress of the project are found, and the key chain identification of the multi-project overall management plan is carried out. At the same time, according to the importance of the project and the importance of the process, mining the use rules of the bottleneck resource in the multi-project, balancing and coordinating the resource conflict caused by the bottleneck resource in each project, get the initial key chain of the multi-project management; Thirdly, considering the influence factors such as process location and process complexity in multi-project management, a new buffer setting method suitable for multi-project key chain management is developed to reasonably eliminate the safe time and set buffer. Determine the final key chain of multi-project management; Finally, through the implementation of the key chain management plan based on multi-project priority, it is proved that the management model is easy to operate and scientific in the implementation of collaborative management of multi-project schedule. It provides a new method for enterprise development to implement overall benefit maximization management.
