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，
" ^. ?  Z5 b& ~) y/ N1 |7 F! A  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.
: u7 u$ t8 A( Z5 V3 A  Loads are processed by each operator for the following time:
9 _! T, s! ?$ _2 A8 H  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.
8 w3 \& }5 t) J+ ~3 {, I: I$ [  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) c" Q8 d# Y$ S2 E) bSend 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.
% Z4 k8 @- D1 a0 s
问题：
$ b- @' j: ?% XAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
. \0 P. P! c5 D, K* Y7 rmove into Q_wait /*Capacity is infinte*/
4 G8 W7 K# E, Imove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
: V# c0 D1 J8 m

end
1 o' p; U, x; A* ^- W9 b
P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min

) b: X' I3 x% f0 Z$ F" a
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.
