本人初学auto mod,有一道题目希望大家赐教

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，
  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.
, F0 N! r# ^: j$ V% V' [6 \3 B  Loads are processed by each operator for the following time:
1 V" }# I9 q1 D! X* t3 n  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
Send 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.

begin P_A arriving
; q8 k# W6 B" M6 u; t8 _move into Q_wait /*Capacity is infinte*/
. |$ }* `/ D- D/ c! Q9 y8 T' Z# Ymove into Q_process /*Single capacity*/
; ]4 w1 c  \# h" P# a
& J8 f" f) O/ ~# C4 i5 Puse R_A for n 60,10 min /*Resource A*/
( c3 I( z5 W* E" E8 o) s0 n! ?6 ^
send to P_B
end

P_B and P_C is similar
; v8 Z, q0 _* ]# n  utriangular 30,60,90 min
u 60,30 min
' U9 }3 F" o% M

in P_C, you need to send to die.

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


Remember to turn off the animation before you run your model.
