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,5 x2 E: A, N1 ^: _
  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.
; q3 y$ k; w, [( y9 T  K, H1 b8 w  Loads are processed by each operator for the following time:+ j7 X9 m0 {2 N- [" T
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.0 V, w0 C8 H$ a) d! }
  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.
2 w  X9 a5 m8 x$ J3 l6 K1 `- s  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 T8 L/ I' G# D0 n& G2 `: f6 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.& C* t2 L: G: m# d/ [3 A" u* b/ A
