目前我国很多项目都具有规模大、结构复杂、技术难度高、周期长、资源约束、相关单位多等特点,因此此类项目进度受到的影响因素也较多,这时项目进度管理就起着至关重要的作用,可以说项目进度管理是项目成功与否的关键,而关键链法作为项目进度管理的重要组成部分,研究基于资源约束的关键链法可以进一步丰富项目进度管理方法的理论体系,不仅具有理论开拓价值还有一定的现实指导意义. At present, many projects in our country are characterized by large scale, complex structure, high technical difficulty, long period, resource constraints and many other related units. Therefore, the progress of such projects is also affected by many factors. At this time, the project schedule management plays a The key role of the project can be said that the progress of the project management is the key to the success of the project, and the key chain as an important part of the progress of the project management, research based on the resource constraints of the key chain method can further enrich the project schedule management theory system, Not only has the theory to explore value there is a certain degree of practical guidance.
