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,3 D6 C" \: ?& {2 Z; a
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 k' }7 M. A2 Z% w/ ?$ ? B3 z
Loads are processed by each operator for the following time:
. t! l6 T/ q! S8 N2 @5 ^ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! K& x5 P- a* N9 b9 C3 K. V- m" \
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.& R: A5 ]4 `% j
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ C7 b! z% o7 S- Q$ USend 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.
