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,
* B T0 V! U. h/ t- h1 Y3 E 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.: T/ R8 o/ `7 z( X
Loads are processed by each operator for the following time:2 ]- w" H5 P2 H! L; {# F
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 n9 @1 {8 ^4 a( l4 P8 L& Z
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.
1 k6 ^9 m8 ?. n Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
E! X" _8 P7 `) } [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., Q0 g; w) q& B% ]
4 Z1 t6 Y* W; g& R3 R2 K" f
问题:( K* |( g, @2 B7 ~, y3 N
After running the model for 10,000 days, what was the average number of loads in each process?+ ?& r5 @' Z3 Q6 h C. @( a% @- u" v
9 F+ E/ Y; t6 u) y( Q6 B不胜感激! |
