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,0 x" o+ a) c, w5 |& K2 M
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.
2 \8 b L7 P: w; P( |7 A Loads are processed by each operator for the following time:
: _( F& b& m+ J Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- }* w: z) n6 N0 G 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.- M) d0 r% f' l8 k/ k' v% s# a! ?- v! k9 q
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.

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