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,
3 O: J- x* L' C8 O 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.0 c! I0 q, k7 z' F% Y
Loads are processed by each operator for the following time:
7 [* ~! O& B4 w. s Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! a; J$ W- W1 R* @( t& P 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.
) c. |4 S& X, D9 S& `/ p9 N; O Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 P4 C9 I# C+ `1 ?' mSend 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.6 n* v7 H" i& L$ f
8 d( j; G6 s1 h' m
问题:3 N2 ^) W. X$ i1 O# o( j0 t
After running the model for 10,000 days, what was the average number of loads in each process?
% `3 C/ L! t. @ N2 B
$ ~4 r" ?# x4 `; S# n不胜感激! |
