工程建设是一项庞大的系统工程,存在投资大、周期长、高技术、高风险的特点,而业主方往往由于技术力量有限,无力对工程的进度和质量进行控制以保证工程的实施成功。因此,在工程的建设中引入网络计划技术则成为保证工程进度的一项重要措施。 The project construction is a huge systematic project, which has the characteristics of large investment, long cycle, high technology and high risk. However, due to the limited technical power, the owner often can not control the progress and quality of the project so as to ensure the successful implementation of the project. Therefore, the introduction of network planning technology in the construction of the project has become an important measure to ensure the progress of the project.
