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,
7 I* @" z( a$ B0 b' T# ]. G( A1 c  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.) r1 l1 [" f, N1 P+ T$ t3 p
  Loads are processed by each operator for the following time:
5 s7 v# y# c' Q5 ~# P# ~  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
# o! i; `. F0 k  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 A' e( [- P+ S- B/ `" E  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- q: ^; M4 _6 X2 r5 F7 o
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.
