网络计划技术的基本原理是:应用网络图的形式来表达一项计划(工程)中各种工种工作(任务、活动、工序)的先后顺序和相互关联的逻辑关系,以科学方法求算出计算安排中的各工作时间及关键工作和关键线路,按照相应目标要求与实际可能情况改善网络计划、选择应用或指导实践的最优方案,并在付诸应用过程中进行有效控制调整与监督,从而保证最 The basic principle of network planning technology is to use the form of a network diagram to express the sequence and interrelated logic of the work (tasks, activities, processes) of various types of work in a plan (engineering), and to calculate the calculation arrangements in a scientific way. Each working time and key work and key line in the company will improve the network plan, select the application or guide the best practice in accordance with the actual target situation and the actual situation, and carry out effective control adjustment and supervision in the application process, so as to ensure most
