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.
  Loads are processed by each operator for the following time:
  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.
4 N8 y' A; q4 _- u; z  J  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, Z# {6 ?+ ~8 S/ b' {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.
: a: j9 e  `) i* ~8 O2 X) Q% U: U
问题：
( J" ?, P- l7 `! W- s4 ^% a; d7 MAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving

move into Q_process /*Single capacity*/

send to P_B
end

P_B and P_C is similar

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