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，
, S5 z  n* T7 P$ Y5 L3 T# ~: Q  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:
7 r, W- Z" }( G; R& x3 f: b  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- \2 X' W6 t3 u" `" ?" N  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.

& ~2 T' y/ M# \$ C( W7 N/ Q问题：
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*/
6 F7 ?; U& Y3 N" V0 [2 |: J8 z; Zmove into Q_process /*Single capacity*/
# W6 h7 J) G- H9 ]# j  K
1 v/ ^3 e( L2 G% yuse R_A for n 60,10 min /*Resource A*/

send to P_B
. j8 ]% J+ P5 u9 n& R4 nend

P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min


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.

; \8 `: \+ Q6 k: ZRemember to turn off the animation before you run your model.
