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,
8 P/ P& ^" x2 r/ Y, u' \ 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.6 H2 e! o) ^6 i7 M/ ?
Loads are processed by each operator for the following time:
! R; d& ^/ R5 V( N Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; j0 g- V( _9 [# q$ C
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.7 {: e, s* ]! V
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) t& Z% h) N+ iSend 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.; x2 w* X% n, S: K4 `1 I7 ~
" ~2 I- w/ A" v
问题:

不胜感激! |
