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,
# K. w+ V; t G% 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.9 O/ ^3 C7 g4 ]5 e8 z: L( U' g* j
Loads are processed by each operator for the following time:1 a! ~& F, D& T: M# R) d% K8 @1 q
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.9 s5 a, {& x* E# o
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.7 ?/ z4 a, @/ [ B
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% t5 X) w# ^0 F7 P! M; f& USend 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 A6 F4 x) s+ ?9 n/ h: t
* t9 C9 G- J) Y; G( s% o/ L9 K
问题: f$ J* z4 W0 g/ Y( a
After running the model for 10,000 days, what was the average number of loads in each process?- x1 e- h# d, N2 N" J$ G
7 ?) ?; L1 \8 W6 ~& P/ J% H! }不胜感激! |
