本文从工程经济的观点研究多局址模拟网向数字网的最优过渡策略,提出了在资金限制下多局址网路过渡的数学模型。采用大系统分解-协调法对模型分析求解,并进行了数值计算。
This paper studies the optimal transition strategy of multi-site analog network to digital network from the perspective of engineering economy, and proposes a mathematical model of multi-site network transition under the financial constraints. The system decomposition-coordination method is used to solve the model analysis and numerical calculation.
