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,
$ w9 U/ p/ {7 @& m" \7 ] 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/ V3 _7 f+ ~* w" q7 f* `
Loads are processed by each operator for the following time:
. @+ V# w& X, w q( q1 z4 a Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 w3 q, e! H" ^ 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* R" H, ]3 K, J6 W Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 G. _9 Y+ Y3 K8 uSend 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.
7 f6 c1 ^1 D' R7 j0 z" p. s4 X# ?0 e
问题:
5 P7 T. c) T6 I* V) p; oAfter running the model for 10,000 days, what was the average number of loads in each process?
3 H, I3 z* X0 i+ Q& Q- @+ n2 V$ p9 n1 z, U/ r* {. P
不胜感激! |
