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,, q9 Z d0 m6 J# z* d* p1 o
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.
, Z2 Y* `# J' L G Loads are processed by each operator for the following time:5 y* K( d/ q, L O- D3 _
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 l n) H8 g$ z/ s: W$ |% `3 S
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.
7 y2 ]9 n; N6 ?4 K/ { Worker_C does the job in a uniformly distributed time between 30 and 90 mins. e: e a0 g, f+ p7 Q
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 H" }; z" i: V' J) L0 W: m
1 d% n; ?* X$ r2 O- F3 X) x# f
问题:) y0 Y; e' ?! h$ k
After running the model for 10,000 days, what was the average number of loads in each process?0 B2 q8 ]" E5 }
