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,
9 C- F( c* }/ b: q+ }% t: Y; d# Z, W 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.$ o8 x1 h( ~* A2 `! g G7 [7 u
Loads are processed by each operator for the following time:
3 ^/ N/ { A4 G" G0 j) s Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.) ~+ f$ b1 O! a5 q
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.
( Y* J- Q: K4 q0 k% d0 T Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: ?) U# c, t4 ^8 J
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.7 {9 W" }: ~# s& o. V
9 G3 T. F) _" C, I) ]问题:( d, _5 U( o9 V3 x- l% ?
After running the model for 10,000 days, what was the average number of loads in each process?
