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,# X5 a: A0 p7 Q2 C0 t9 ?. f
  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.
/ j( e' @: [: E) u  Loads are processed by each operator for the following time:  Y' f+ S  U" e" X, N
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; X& Z2 p( ]% _5 y% 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.: ^1 W2 a; M( B/ e* W- i6 I! z
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
  M% d1 `4 a$ Y7 k/ LSend 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.* r8 _7 B: z. P" q, O

in P_C, you need to send to die.9 m. ^$ Y% ^2 U5 m5 d# x

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
