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,' b5 J- F4 c: D1 j
  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.
2 u4 G3 K3 \# C( n, e1 Y( w  Loads are processed by each operator for the following time:
, Z& n0 e; @9 o/ L/ |9 r3 ?8 ^( j  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 F, G( z9 b( c$ u3 J# K+ i  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.
; Y) h) y/ X( V  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
4 D6 G1 [! X3 r$ a4 tSend 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.0 ~* g# {( K$ h% V6 a2 A0 V( ?

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
