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,
( A, Y, r a# {& [5 |, e 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, R: ]6 u) T; d. M" R- v7 F Loads are processed by each operator for the following time:) Y$ H8 |( C& v( ^" E
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 X1 N" }# d0 t 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.
4 O7 e/ N! @1 O5 Y" h& U Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: v3 Q# [! @. [" _$ K3 w8 ^4 E% R; 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.0 {- d0 E1 w. |: D
- C+ O. m* v5 C- W
问题:5 Y1 v5 p' q! R: \- O
After running the model for 10,000 days, what was the average number of loads in each process?$ m" [) M' [9 L7 e
/ S: u# L! J% n+ O
不胜感激! |
