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,
! a7 a5 {/ I$ m. W0 ^ c; @' L& S5 A 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.
~) `: y' @; w. m Loads are processed by each operator for the following time:6 [" \' D6 q6 p: B
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 E5 t+ p" m4 Z$ S! c' [
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.
! a! Q1 P' m( E& a5 B$ W- X( I Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
. j' ]. D4 d6 l5 A( v4 L: L1 D/ k* ?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.
: m* Y+ S6 B4 t U2 Q; L/ v; v
6 V7 _# @2 p: b/ `' Q问题:' B0 t0 |) r$ \7 z
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
