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,
+ Q$ r, x; a) m5 q. q 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.
; Q$ j. ^2 Y3 m. x Loads are processed by each operator for the following time:, w" |1 m6 \- o4 f" ]. a
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! l, r, t. i* s& ]# g. s
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.% d, r s) Z4 j& A6 t3 A
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.' H: u- H8 Z+ t1 _
Send 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.
# `$ h( v) s4 a# E& H3 v) X. h+ ^7 w* J f4 x7 C
问题:
/ f1 T7 u, p/ _After running the model for 10,000 days, what was the average number of loads in each process?
