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,: N; X2 P& E. `% R. A
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.- `. k; S! A% A7 c- D
Loads are processed by each operator for the following time:, U7 m6 C/ W$ z* c; V
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
1 a/ y9 k; F0 j9 ^) J6 w0 ^ 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.) n& p. D8 q( c/ o% Q, b
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
$ e0 d% p) p5 P( T% B3 D0 s0 u) ZSend 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.
% Z) J# m, s+ ~1 q; g9 i( h( n3 F
问题:# C6 q- N1 k9 Q
After running the model for 10,000 days, what was the average number of loads in each process?
