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,
, }8 _6 X& V/ K) L, Q; H4 R 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.
( f* J+ G' N9 T Loads are processed by each operator for the following time:/ L6 u8 ~( K9 b- f* r
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& ^* S, E; w" Q! L! o
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.
4 W$ ]" R4 ~6 k" {2 Y& M Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- }0 \. H. V) T Y' O0 V1 LSend 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.
% I7 P' Y- |2 r9 z1 Y1 |- O c5 b
问题:" X: H6 Q, M- w9 N: u# u. }; M4 u
After running the model for 10,000 days, what was the average number of loads in each process?7 G; G1 M' P2 u# q5 i/ D
