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,, e; Q; G4 Z. m. i+ P4 T, M
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.% p8 }, v. _/ \
Loads are processed by each operator for the following time:
5 s9 Y H6 Q# C2 ~ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." l/ v2 P8 F) s+ n' q
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.
$ @+ l# { w$ M- |$ @5 n Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: `% v7 G1 E: z' ]- bSend 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.2 O; P+ h8 b4 f: D, c0 B$ [
, `# r; V/ }/ y+ B+ m" G问题:! i4 Y9 z; W: t9 l8 |3 H
After running the model for 10,000 days, what was the average number of loads in each process?7 R1 _/ j/ J: \- \) z9 m1 O a% E
