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，
, K+ B! ^% y- m6 @, K' E: r  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.
# x6 ~/ O+ ]) i2 B! A" Z# k  Loads are processed by each operator for the following time:
8 J' j0 P7 n1 k3 z  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.
% x  T* Q; h9 M9 ^& y. f7 V  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
7 u7 l- t# g( |; g! |move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
( _9 `3 b9 K# n! f" `7 E
use R_A for n 60,10 min /*Resource A*/
1 S7 B/ e6 D/ J
send to P_B

7 Z$ J( a& C, T! h& Y' m1 oP_B and P_C is similar
triangular 30,60,90 min

+ P8 E) o3 E. [/ T
: S) G3 Y$ \. x3 D2 Tin 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.
