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,
9 W) B5 i* \ 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. r( J4 p: d6 G; n$ T+ r
Loads are processed by each operator for the following time:
7 W* H# } k1 m& N Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., B* |% D- V, @
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.' r- h$ c) ]1 n Z3 t2 ?
Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ v- i9 a$ x" F7 q
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.' `9 J' B% j3 @6 z* P* M: ]. Y
$ e, R1 E# P- ~, |问题:$ Q' R1 s2 t! W' [" _1 N0 F8 d# X z
After running the model for 10,000 days, what was the average number of loads in each process?& ^8 P; j a! h* z* ^: Q2 s: q9 ?
& o1 k; O3 N( x" }, g0 {% z, R; E不胜感激! |
