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,
/ u& E% I0 Y8 |4 @! y$ k 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.4 T0 e4 j5 V6 V7 i( i
Loads are processed by each operator for the following time:! A" e( }1 S# }, b' H9 H
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.+ [( d; u0 q9 S/ D) D7 s8 G$ m
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.
& p! M( z9 a$ L/ D Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
( }# H) d/ A$ ]6 z4 gSend 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.; w& {1 H" g, ~" O" L
" l0 E! g7 O }) [4 X问题:
! E" c p" s( T/ t& V! bAfter running the model for 10,000 days, what was the average number of loads in each process?" B/ m% o2 k! K- l. F
