文中探讨了利用井巷工程二级网络图求算总体一级网络图中各工程的时间参数的方法,以及如何建立具体安排初始方案的方法,然后利用表算法求可行方案与理想优化方案,进一步确定具体条件下的优化方案以及井巷工程具体安排的形式和方法,并以现场实例加以说明. In this paper, the method of calculating the time parameters of each project in the overall network diagram by using the secondary network diagram of the roadway engineering is discussed, and how to set up the initial plan of the concrete network plan is discussed. Then, the table algorithm is used to find the feasible solution and the ideal solution, Determine the specific conditions of the optimization program as well as the specific arrangements of the form and method of well engineering and field examples to illustrate.
