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,/ h! w3 Z8 ?) }7 Z( |
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 Z% g8 n1 g" }9 K+ W: V, G
Loads are processed by each operator for the following time:) k3 _% F3 F" L8 _% Z: s
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 L. i( z6 Z5 T: D, m% G
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.

After running the model for 10,000 days, what was the average number of loads in each process?
