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,: X: u4 W0 y x6 R
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* p& n/ ]/ Y) N1 j0 u8 R Loads are processed by each operator for the following time:% T+ y& v( h# e$ h& |
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.% C; M" o" B, {9 M+ W3 A
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.3 u* j; y0 `7 x d+ x1 q6 z
Worker_C does the job in a uniformly distributed time between 30 and 90 mins., B8 }5 r6 ^6 A! m/ v
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.. A0 a7 M" z7 N; R, N

After running the model for 10,000 days, what was the average number of loads in each process?+ I8 e6 A& n& [$ ?" U
