网络计划是以合理安排施工工序为基础进行组织施工的一种现代的科学的生产组织方法,其特点表现为生产的系统性、条理性和逻辑性,它具有清晰表达各工序之间相互依存和相互制约的关系,正确地反映计划中的关键线路和确定计划工期,以期在规定的期限内合理地使用人力、物力、财力,有计划地完成工程任务。网络图突出了主要矛盾线,可根据主要矛盾线压缩工期,并由此计算出在非主要矛盾线上可供利用的时差,以解决部分工种的平衡。在单位工程主要施工过程网络图中尚可附带时间座标、工序名称、工程量和劳动量等内容,对整个工程有一个清晰的认识,做到通观全局,抓住重点,取得主动。并可根据经济活动的现状,对施工进行规划和预测,为施工过程中不断变化着的情况因势利导地进行指挥,适时地采取措施,进行有效的控制和监督,真正起到组织生产、促进管理的作用。随着现代管理科学技术的发展,生产社会化的提高,网络计划的应用将进一步从单位工程、建筑群为对象发展到建筑企业整个管理系统上去,其经济效益将更为显著。同时尚需对企业经济活动中的数量关系进行计算、分析、比较和处理,建立健全的情报资料系统,数据要力求准确、全面和合理,这是编制和实施网络计划的前提。
The network plan is a modern, scientific production organization method based on the rational arrangement of construction processes. Its characteristics are characterized by systematism, organization, and logic of production. It has a clear expression of interdependence between processes and The relationship of mutual restraint correctly reflects the key lines in the plan and determines the duration of the plan, with a view to reasonably using manpower, material resources and financial resources within a prescribed time limit to complete the project tasks in a planned manner. The network diagram highlights the main contradiction lines, and the construction period can be compressed according to the main contradiction lines, and the time difference available for use on non-major contradictions lines can be calculated to solve the balance of some types of work. In the network diagram of the main construction process of the unit project, time coordinates, process names, quantities of work, and labor amount, etc., can also be included. This has a clear understanding of the entire project, so that we can look at the overall situation, grasp the key points, and gain initiative. According to the status quo of economic activities, planning and forecasting of construction can be carried out. Conducting the command of the changing circumstances in the construction process, taking timely measures, conducting effective control and supervision, and truly organizing production and promoting management. effect. With the development of modern management science and technology and the improvement of socialization of production, the application of network planning will further develop from the unit project and building group to the entire management system of construction companies, and its economic benefits will be more significant. At the same time, it is still necessary to calculate, analyze, compare and handle the quantitative relationships in the economic activities of enterprises, and establish a sound information and data system. The data must be accurate, comprehensive, and reasonable. This is the prerequisite for the preparation and implementation of the network plan.
