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,
1 F: T* Y5 L6 k5 { 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.
; l! c: O8 F8 [* V. x Loads are processed by each operator for the following time:
0 T& H4 p' M. e, n Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 w- e0 k4 M# J0 h& 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.' g9 p2 X6 X/ d
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.% F, u; P, o+ M$ Q5 m- A' 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.
0 n/ ~8 }2 ]0 r0 Y1 T% u% n( X! n$ s& u3 ~( M! X
问题:4 T* _0 W4 x3 M* j
After running the model for 10,000 days, what was the average number of loads in each process?9 q2 |9 F9 o# R2 W) C, s, A
