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 L. i, d! z5 A' b 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.
! @! e' I1 E" o- j' f Loads are processed by each operator for the following time:
0 d! b* T* t# J% b9 [ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 Q* [; h. {/ w; X+ 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.
9 N7 [( O! @2 _0 x- @ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 E7 ?- D9 e2 ]4 sSend 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. i B! t/ @$ F) U2 G
4 d6 u" C1 C8 k: \( F
问题:, |6 p! o1 |8 A! E, @' M0 ~* u
After running the model for 10,000 days, what was the average number of loads in each process?
