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,
$ n- w: t8 F+ C. G 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 r- U& e" r$ ^# F Loads are processed by each operator for the following time:
" L+ s4 v3 F; y% s& a Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. [2 o- E, `, h, }
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.
% o( [7 I' C& K( u Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
! I- l! t/ }- @4 b( vSend 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 T9 G; @- ?- X0 _1 U+ G" T( _& L0 `. P% @# W) @4 }$ ^& j V
问题:( K/ R' \/ d" x$ o
After running the model for 10,000 days, what was the average number of loads in each process?
