Erlang
根据Erlang B公式进行程序设计：
（1）输入：话务量、信道数；输出：PC
（2）输入：PC、信道数；输出：最大话务量
根据Erlang C公式进行程序设计：
（1）输入：话务量、信道数；输出：PW[延迟>0]
（2）输入：PW[延迟>0]、信道数；输出：最大话务量
(According to Erlang B formula for program design: (1) Input: traffic, number of channels output: PC (2) input: PC, number of channels output: maximum traffic based on Erlang C formula for program design: (1) Input: traffic, number of channels output: PW [Delay> 0] (2) Input: PW [Delay> 0], the number of channels output: maximum traffic)
