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,
I; L$ l7 K! ~% v2 m 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 E9 g% P# ^ n) P8 _$ Q; i2 S Loads are processed by each operator for the following time:# {6 f- p& V8 C
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 ]3 w! p% D$ m1 f- u 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.( O# r4 n( l D" Y6 n8 Q% X" T
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.0 h7 S" O* f- M# b2 m/ z$ P7 R
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.; R# y9 f0 x) w* f: ?4 T4 A
. O, v2 R. S2 d; {# ]- K
问题:& g- ^$ v" Y$ I# V3 j* C
After running the model for 10,000 days, what was the average number of loads in each process?4 g p3 Q7 y5 b- {. q: ~
