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 y7 ?* W" w 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.
, i# w' z+ i0 ]1 t Loads are processed by each operator for the following time:! V! i6 p1 K3 D& P: V) Q5 R9 s
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, I! p) _2 @: k. S I: ?2 r 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.
+ w7 b' i& ]+ }/ t! ] Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 Q1 z! x/ }5 S! ySend 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.8 t( H$ ^9 ^) u

After running the model for 10,000 days, what was the average number of loads in each process?6 Z0 o4 O+ y! B" j
