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,
3 l+ f4 `: ^$ l$ [ 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./ L/ n$ s, r+ ?
Loads are processed by each operator for the following time:
6 {; k' y, T" o: U* A Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* a. B; d* n4 j; Y7 { 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.
+ t# G' h! ^" l9 y! c' D Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- s: \/ H4 R+ `8 G7 P. Q3 ^7 r4 }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.
* y) n& H# g5 j. U: R( Q& P. C' C6 h) W) Y4 E/ \$ A
问题:5 P/ z0 e t8 \- N2 m2 r
After running the model for 10,000 days, what was the average number of loads in each process?
