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,9 z4 h H- y: U2 {- ^* I
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.' s+ ?$ C8 q0 v7 O0 u1 r$ F
Loads are processed by each operator for the following time:; |* f, E6 {+ H3 h; z. ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- x& f8 u8 |$ l& u, ^7 M 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 N7 E- s5 N6 n# d
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.$ k" E8 S- X( V* l
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 ^5 \$ m6 I$ E, i
) r5 L" p: l* |$ F! }
问题:9 v; I0 p/ L. B. H
After running the model for 10,000 days, what was the average number of loads in each process?
