合理设置地铁车站的公用电话系统 ,涉及的因素十分广泛 .根据系统工程的观点 ,以上海地铁一号线的实际运营情况为基础 ,通过采用解释结构模型、一元线性回归模型和排队论模型 ,对此进行了详细分析 ,并首次提出了解决此类问题的基本思路 .由此得出的有关上海地铁二号线的某些具体分析结果已受到上海地铁总公司的重视与采纳 ,从而在经济建设中发挥了积极作用 Based on the systematic engineering viewpoint, based on the actual operation of Shanghai Metro Line 1, through the use of the explanatory structural model, the univariate linear regression model and the queuing theory model, This is a detailed analysis, and for the first time put forward the basic idea to solve such problems.Therefore, some specific analysis results of Shanghai Metro Line 2 have been taken seriously by Shanghai Metro Corporation, so that in the economic construction Has played a positive role
