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,
: q3 `6 X3 d$ i& ^+ t E 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.
; Z! y. Q }" M) `& z* g Loads are processed by each operator for the following time:+ [9 [$ F2 M8 A% p6 n* r7 h$ D! l
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.0 H& u* N$ @- l
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 ~$ d5 k8 s* M1 g Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- u; k5 X0 F& I! @6 V( LSend 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.9 H' G8 ?- }0 K
; G+ ?% b" ]' i* s$ k M* {/ L8 D
问题:5 T8 x9 \1 F. D7 ~ r, y, M
After running the model for 10,000 days, what was the average number of loads in each process?
