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 Z% B4 b) W( Y; l& j* w8 B  O
  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.6 c, F2 i, w4 B+ O) c
  Loads are processed by each operator for the following time:9 n! e2 A( C3 Y% e# @2 G
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
( C! j+ y8 l* Y5 @9 t/ J  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.: n( v3 m. }8 }5 y% w  p) o6 O$ k
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 i% e+ X5 d3 o0 pSend 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.4 ?8 V; p: t$ Y7 o( [
