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，
0 n& _" T  k7 \2 t  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.
% {: ]4 s; k& e2 |  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.
: O# D: v$ ?" T7 |" M# R1 O1 B. s! Z  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.

问题：
- J) C% M. N% I# ~: m; L4 ?After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

$ z5 f! q$ F4 Luse R_A for n 60,10 min /*Resource A*/

; H6 y6 J9 t7 Iin 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.
