【摘要】 本文以机车计算速度为设计变量,以投入(万吨公里相关运输成本)最小,产出(机车生产率)最大为双目标函数,采用多目标优化技术在微机上求出了我国主型机车的经济计算速度,可供运营与设计部门选择机车计算速度及制订铁路主要技术政策确定速度、重量、密度关系参考。

【Abstract】 n this article, the selection of computed speed of locomotive on operating railway is modelled with the computed speed of locomotive as design variable and minimizing cost (related cod of transport per ten thousand the-kilometer) and maximizing production (locomotive producivity) as double-objective function. Based on the model, the economical computed speeds of principal types of locomotive in China are found by using the technique of multiobjective optimization and microcomputer. The calculated results can be utilized by operation and design units to select locomotive computed speed and to determine the relationship ot train’s velocity, weight and density in formulating railway principal technical policy.
