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:
5 ~5 I( o  N% E& B1 Y8 W9 [& V, O  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 s% W9 d/ }% l1 ^! i5 ?$ D  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.
9 m% A* y9 {- e- W/ v1 u$ L  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
move into Q_wait /*Capacity is infinte*/
3 h7 P' [* ?( W5 k6 `! imove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/

send to P_B
end

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.
