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 o9 M* U. F' _% K* l8 s1 h 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.
; e/ q1 ~+ ?* V) \6 J, L Loads are processed by each operator for the following time:% p7 D9 J \) `7 [
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 I% ]& [% V/ E2 N' ]+ V" S2 _ w
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.* z- \/ E: t+ y/ n7 r
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: ?8 H+ a" ?# I: ] X" N) Z/ ^
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.; ^4 u; z5 S/ |$ H) z

After running the model for 10,000 days, what was the average number of loads in each process?# V" F; ]- T. K4 R6 l
