刚刚开始学auto mod,这道题目搞不明白,希望大家看看 题目是这样的,
2 p/ t( U7 g( `% Y/ l# ? Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.# {- C a8 ^8 V( c6 E& {+ Q8 N" |
Loads are processed by each operator for the following time:, _( r. t% e/ M7 B' C
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% l+ I2 a0 W+ e, d( l Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.
4 ~' F3 N& N7 U, D1 D Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
' U, s- D" i) r9 x5 M9 fSend loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers.9 a3 b" H5 }7 z# B& P4 R9 n* p

问题:
