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,* p$ C0 N; |5 @4 W. F& l7 u
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.
5 G2 b& T0 b) ^* J# d3 ], c Loads are processed by each operator for the following time:
3 D7 J( E' m }! O6 y Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
( S0 A; [; O# E+ b4 N 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.
( c5 t; U3 T- z8 s' i4 [ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 T1 T) \4 F* X( g/ pSend 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.' F9 K0 V' e, u2 \- n1 ~

问题:# i$ T% [0 B4 w
After running the model for 10,000 days, what was the average number of loads in each process?
