费用问题是有线通信网络建设过程中的重要问题。针对通信网络费用计算过程中的拓扑结构问题和定性值量化问题,分别研究了“演进法”和“拟合法”。其中“演进法”大大减少了拓扑结构选择的计算量,使多节点连接方案计算成为可能;“拟合法”为多层定性值的量化提供了手段。把这两种方法综合到仿真计算过程中,为选择费用最小的网络连接方案提供了支持。
The cost issue is an important issue in the construction of wired communication networks. In order to solve the problem of topological structure and qualitative value quantification in the calculation of communication network cost, the “evolution method” and the “fitting method” are respectively studied. The “evolution method” greatly reduces the computational complexity of topology selection and makes the calculation of multi-node connection scheme possible. The “fitting method” provides a means for quantification of multi-level qualitative values. The two methods integrated into the simulation calculation process, to choose the least expensive network connectivity solutions provided support.
