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,
7 [. Q& `$ \( {; p1 {9 q' ]$ T$ a 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.
' `* z# G$ P8 a( E: m Loads are processed by each operator for the following time:" V" p8 b3 G6 Y
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.% D3 q8 z8 V* @4 c g
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.0 v% A# S: M6 I+ f: R S" ]
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
! H! d& E* g' w8 ?( h# U$ ESend 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 n1 S, U) |% w2 [* M
3 A) B) g7 n1 F: i问题:" k: @/ l x! W4 `0 W
After running the model for 10,000 days, what was the average number of loads in each process?% U, ]" f, j1 D
