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,
; d f" z; l. ]6 N4 a* i 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.% I' P. v7 O0 s E2 V
Loads are processed by each operator for the following time:! G' V# E* E$ J! R/ o8 {5 o
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.+ p6 W% H! x: z. T: Q) l
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.9 \2 n# k0 G5 G6 c4 ^, ], E
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; x$ _* [9 c$ H( {2 i) B
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.* I% x \: Q! {4 D
: Y+ Q" ]! F! [( A' V3 J/ ~+ b5 y问题:+ R% {, z3 Z) M
After running the model for 10,000 days, what was the average number of loads in each process?8 B! F+ r Z+ y3 |
