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,, L3 x4 V( k* E+ _6 b( d
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.8 Y0 u ~- d5 o% _9 L
Loads are processed by each operator for the following time:
) F$ \5 |9 O1 B5 m Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.( _' i f# S! ~( h5 q6 r7 l [
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.! ^) N: j0 Z- `1 @$ F, L7 E1 q) A
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- J* n( z8 }, y4 E, X2 `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.8 S0 w' Q6 B3 n4 u6 b

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