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,6 ~; F K" L/ X5 M# g* V
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.
1 A1 H! D+ H9 m' D; \( ~( w1 V% F8 y Loads are processed by each operator for the following time:
; m& ]- x* m, M- Q6 e Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 l1 R! w( ~/ c( @
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.
% j% H8 n* W4 W Worker_C does the job in a uniformly distributed time between 30 and 90 mins.$ ^$ _, ]8 T& q
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.% p9 y9 ^9 Z! K6 Q \
0 H3 q7 F& [* `' ]2 r# p问题:, @& t; C3 w0 x$ {4 i) p
After running the model for 10,000 days, what was the average number of loads in each process?- i* w: d) M; F" m
