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,
1 G# z$ {6 @1 R; D- F8 m 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.2 k8 ^( W @1 c5 Q; U! D& L
Loads are processed by each operator for the following time:
1 M2 A* S4 Q$ X2 P; I+ m Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% o6 F3 P8 @( v! k( l U9 c8 f5 f 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 ]; l6 l' g0 E1 o- N+ r Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 R: }+ ]( D# P4 ^- g) LSend 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.% r! p d$ L3 v: V# Z
1 ^- f0 E- J3 u7 \' l; M问题:$ I- c4 D( ~, [+ A
After running the model for 10,000 days, what was the average number of loads in each process?
( K) r- Z* }- g& e1 H% X
" s/ a. t v) h! L3 y6 P不胜感激! |
