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,1 u1 C, @8 _, h: ^4 S# L+ F
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. N" ~/ ^' y/ j- I& T
Loads are processed by each operator for the following time:
* m A* t! ]- [ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 k1 l. t% w' w. ?5 l4 C 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.
7 a' n- ^) g6 R% l. Z7 F- o- [1 s Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 m$ A' S! @0 F# SSend 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.6 ]$ _0 t% l+ i$ b
! [5 z. J4 k8 K% A$ n; ?8 d
问题: p& t5 V# S+ J. v
After running the model for 10,000 days, what was the average number of loads in each process?
