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，
& j; T; L; q% C% W& L7 w  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.
9 }/ L' l, I& {( ?; B  Loads are processed by each operator for the following time:
' |3 k: ~$ B1 q2 |  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
; R$ }% h4 e' |* h1 |; uSend 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.

7 k# e: a! E% Y7 y问题：
' P( G- M- U; hAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving

send to P_B
end

P_B and P_C is similar

; E, K: q( f5 x/ bu 60,30 min


in P_C, you need to send to die.

) u2 y# e; e# g9 O# P4 q: q" SThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
