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,
* G5 \0 E) b0 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.
* z" N% N, r9 O3 g/ S. Z9 L Loads are processed by each operator for the following time:, U, C" k3 _7 V. c! x
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* I" H! r: {7 G3 j) \ 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.
# C. \) t" ?) T7 q; B Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 Z9 Q4 g7 U5 \ `5 ]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.
! l: J6 A. ~3 i5 S
6 ~7 I$ ? m3 Y问题:% i, G& `0 ^2 n3 r# e, o! ~( i
After running the model for 10,000 days, what was the average number of loads in each process?' b$ m4 e- K+ h- Q4 {% ]+ ]
