【摘要】：随着我国电信技术的发展,用户需求日益增长,电信市场进一步开放,移动虚拟运营商于2013年进入电信市场。移动虚拟运营商的其核心竞争力不只是传统的电信资源,更重要的是业务支撑系统(Business Support System,简称BSS)的服务提供能力。因此,按期完成BSS项目建设关系到我国电信行业的发展,移动虚拟运营商的成长,而完成这个重要目标的关键之一就是项目进度管理。本文运用先进的进度管理理论与传统的进度计划方法进行对比,论述BSS项目进度管理的优化思路。本文整理了项目进度管理的理论基础,介绍一些传统的进度管理方法,包括关键路径法,计划评审技术,分析这些方法在项目运用中存在的不足,针对这些不足引出了对关键链法的描述,着重分析关键链法在资源约束解决、设置缓冲区方面的优秀思想,并对比分析了传统方法和关键链法的优缺点。随后,介绍了BSS项目内容,运用德尔菲法分析项目进度管理中存在的问题,针对这些问题关键链法有较好的解决方案,由此构建了基于关键链法移动虚拟运营商BSS项目进度计划框架,并在关键链识别方面使用启发式算法以最小总时差优先准则解决资源受限问题,在缓冲区计算方面提出了优化方案,即制定了针对不同资源的缓冲区大小计算方法。然后以实际项目为例,使用关键链法制定进度计划,通过横道图观察资源冲突情况,应用框架解决冲突,并处理因为缓冲区的插入而引起关键链的变化。最后根据蒙特卡洛仿真原理,使用Crystal Ball软件模拟关键链法和计划评审技术在不确定因素下的持续时间分布,对两种方法的仿真结果进行对比,验证本文方案在BSS项目运用中的可行性和可靠性。本文以项目管理知识为基础,论述关键链法的理论在移动虚拟运营商BSS工程项目中的应用。针对“移动虚拟运营商”这个崭新的角色,预期找到适合它的项目进度管理过程与方法,对今后其他移动虚拟运营商BSS工程项目的进度管理工作能起到指导作用。
[Abstract]:With the development of telecommunication technology in China, the demand of users is increasing day by day, and the telecom market is further open. Mobile virtual operators entered the telecom market in 2013. The core competence of mobile virtual operators is not only traditional telecommunication resources, but also the service supply ability of Business Support system (BSS). Therefore, the completion of the BSS project on time is related to the development of China's telecommunications industry and the growth of mobile virtual operators, and one of the key to achieve this important goal is project schedule management. By comparing the advanced schedule management theory with the traditional schedule planning method, this paper discusses the optimization of BSS project schedule management. This paper summarizes the theoretical basis of project schedule management, introduces some traditional schedule management methods, including critical path method, planning review technology, and analyzes the shortcomings of these methods in the application of the project. In view of these shortcomings, the description of the key chain method is introduced, and the excellent ideas of the key chain method in resource constraint solution and buffer setting are analyzed, and the advantages and disadvantages of the traditional method and the key chain method are compared and analyzed. Then, the content of BSS project is introduced, and the problems in project schedule management are analyzed by Delphi method. The key chain method has a better solution to these problems. Based on the key chain method, the BSS project schedule planning framework of mobile virtual operator is constructed, and the heuristic algorithm is used to solve the problem of resource constraint by using minimum total time difference priority criterion in key chain identification. In the aspect of buffer calculation, the optimization scheme is proposed, that is, the buffer size calculation method for different resources is developed. Then, taking the actual project as an example, the key chain method is used to make the progress plan, the resource conflict is observed by the crossbar diagram, the conflict is resolved by applying the framework, and the change of the key chain caused by the buffer insertion is dealt with. Finally, according to Monte Carlo simulation principle, using Crystal Ball software to simulate the duration distribution of critical chain method and plan review technology under uncertain factors, the simulation results of the two methods are compared. Verify the feasibility and reliability of this project in the application of BSS project. Based on the knowledge of project management, this paper discusses the application of the key chain method in the BSS project of mobile virtual operator. In view of the new role of "mobile virtual operator", it is expected to find a suitable process and method of project schedule management for other mobile virtual operators, so as to guide the progress management of other mobile virtual operators' BSS project in the future.
