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,
0 @, q* n1 b: ?8 L/ q* ~ 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.; {4 `# F1 Y! |$ D5 K8 M
Loads are processed by each operator for the following time:8 n! I0 y) i& }& |. r% G
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: ]- z- n! Q. G
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.
. [; y$ {- ^3 V6 ~' q _3 s E# b( t Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 M( r3 I5 v; w+ ~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.
2 C/ U0 P1 v6 \( J+ `9 d$ ~+ n, o# L0 w
问题:
3 L" i4 R z1 kAfter running the model for 10,000 days, what was the average number of loads in each process?, l" p/ x0 f. P6 x, v5 t( j
/ P8 z& @6 G* h. g% }. S/ w
不胜感激! |
