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 P i" F* d( m6 M* L3 o% ~& r 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.
* s* W' v* }( d Loads are processed by each operator for the following time:
5 w2 G% B9 O, ~) A9 G) V ^ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 ^4 A+ [& f$ `* J* _ 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.
. e* H) S- j4 E% Q; g9 W# _ Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ \( I* z1 D5 i
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./ U$ Z/ q3 L* l5 ^

After running the model for 10,000 days, what was the average number of loads in each process?. \. A, A$ [% S; u
