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,
# f6 q7 W' C( @- S( C8 L# U 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.
0 {. L! O. k- F( P Loads are processed by each operator for the following time:
R# K0 `$ ^- L% C. F9 } Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.( w5 x3 L' y3 ~
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.
- n4 z3 p6 K4 i& D$ J0 z Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 F- U$ E# I h+ k1 z% RSend 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% G7 n* L7 b* j2 R" d; g& C8 v1 Y2 ~( q
问题:
9 A) [- D, y( \, h; o5 u! V1 RAfter running the model for 10,000 days, what was the average number of loads in each process?; O! Y* {; x. B2 S4 K
