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,
" _* _) P1 I: W- I3 x' L% Y/ R  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.7 [; \" O# c. C
  Loads are processed by each operator for the following time:
4 a+ ]1 D% H8 H/ H3 r8 E( D  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. O2 p: R$ N2 N+ m6 A
  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.
5 ~/ k) O) a& ~( [0 U. d% D  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
! D! J* o2 R7 L2 B/ ~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.- U7 a3 H2 N' X3 G
