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,
- E% r8 n. O. e8 ~( ?6 X/ h' r+ 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.4 a0 h5 J8 a; i/ j4 S" ~
Loads are processed by each operator for the following time:# t$ X7 y# `& ]& q( Z5 ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; I* b5 p5 F* s* s; M" Q 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+ p+ e$ V9 f! G! p
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.# w& d; [' A) |3 [
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.8 F9 e- o i* K
9 c3 B6 h( E& B) Q" y
问题:7 Q+ _; w5 u2 {
After running the model for 10,000 days, what was the average number of loads in each process?
