摘要
为了确定铁路集装箱班列的集结消耗,运用随机过程的理论,研究集装箱班列的编成箱数和集结过程中涉及到的到达箱数、到达间隔,并对到达强度进行了参数估计.研究发现,箱流的重、空状态基本上不对班列的编成箱数产生影响;箱流的到达可以用简单计数过程描述,到达间隔服从泊松分布.集结过程可以描述为典型的标值计数过程.班列的平均集结消耗与该方向班列的编成箱数和一定时期内总的到达箱数成正比,并且与到达箱数的期望值线性相关.
To calculate the accumulation cost of a BCT （block container train）, the theory of stochastic process was used to study the number containers of a BCT, as well as the number of arrival containers and arrival intervals in accumulation processes. Parameter estimation for arriving intensity was discussed. It was found that whether containers are loaded or empty has little effect on the number of BCT; the arrival of containers can be described as a simple counting process, and the arrival interval follows the Poisson distribution. Therefore, the accumulation process of a BCT can be described as a typical mark value counting process. The average accumulation cost is positively proportional to the number of container in a BCT and the sum of arrival containers in the period of time concerned, and linearly correlated to the expectation value of the number of arrival containers .
