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,
5 G2 m! e, W, k1 \( ^6 w 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.
1 F/ F) E& C( J Loads are processed by each operator for the following time:
, o: K: x1 O: T: A, a Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. {; `; U" g- M( A6 m/ t, Y
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.
3 f' t4 `# o3 P B! w# y i Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ d5 E! Y# J; \, x& [; \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. k# Z) g0 h% o$ `
5 S; q5 Y8 h6 x! r3 m. Y( M
问题:- T' O! ~, x b6 @
After running the model for 10,000 days, what was the average number of loads in each process?$ K2 P Y: E8 H* G0 {
