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 _! h4 A4 C* M2 T 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.
8 X& q7 r$ U* B Z, z% Q Loads are processed by each operator for the following time:# N3 U) S( ]$ B: M# {
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., R5 c# w4 [# V$ k
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 o6 [6 N. y# F3 N' q; y
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( C! r% [7 r) {; D
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.
. I: M( E P# r! s z( E6 |" x& f& t) O# Q6 z- k$ I$ H! A
问题:, o, @7 \/ q% G0 n0 I8 z
After running the model for 10,000 days, what was the average number of loads in each process?) \: w- L+ i- Z
2 z9 S1 I7 P. _+ @% T
不胜感激! |
