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,
; H9 W' ?1 t& A( 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.
. O* T/ u0 d! R5 j- E+ R Loads are processed by each operator for the following time:
& L1 o% |0 j: X1 l% G; p% }' v( h [ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! l9 M! U, b0 e& M- g! i4 i5 y! `
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.& y$ F6 Y- |: k
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( v* l" Y0 H& s @1 c1 H
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.
1 h" F8 I D4 _+ J7 W' ^% @" z* I2 f4 j' p
问题:0 X* q6 {9 z: ^5 N# d9 @- Z1 _
After running the model for 10,000 days, what was the average number of loads in each process?' y1 Q. y6 r6 q3 ?' l, U0 r

不胜感激! |
