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,
" q6 |; b; R, y9 ^6 h3 b 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.
! o# W3 ?) q: q# L( E1 b. i Loads are processed by each operator for the following time:
* c" N7 j5 R4 S Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! R7 b; s7 B( K# l3 u 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.) P1 F3 ~. C1 B) W% |3 O
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.# ~4 e: F- y7 x/ k, F6 j$ s
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.
" u+ ~, x |" x: V/ m( `8 N1 r* }: R" h8 S6 Z" ~/ x Z
问题:* E g5 N9 p* h" q/ x9 c
After running the model for 10,000 days, what was the average number of loads in each process?
8 T3 e' y3 l$ ~! U$ r% b& k( h% J6 S* K+ U$ o% n! G
不胜感激! |
