对Poisson分布下电梯运行可能停站不同表示的讨论

Discussion on Different Expressions of Probable Stops in Elevator Running Under Poisson Distribution

指出Peter公式和Basset公式描述的事件都是发生在Poisson分布下,在n次试验中的较小概率事件;不同点是Poisson分布的某些具体条件有所不同。给出任意层间交通和确定层间交通的明确定义、可能停站数公式和工程解释,及相应的电梯运行周期。提出了双层轿厢电梯双层运行的层间交通公式。为进一步研究双层轿厢电梯及其组合交通系统的运行模式打下了基础。

It is pointed out that the events described by Peter formula and Basset formula are less probability events in n time tests under Poisson distribution. But some specific conditions for Poisson distribution are different. The explicit definition of any interlloor traffic and the determining interloor traffic, the formula of the number of probable stops, the engineering explanation and the corresponding elevator round trip time are given. An interloor traffic formula for double running mode of double-deck elevator is proposed. A foundation for further research on the running mode of doubledeck elevator and its combined traffic system are laied.
