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,
~; X: D8 b2 B2 k 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.. M6 p0 B8 T* z* G4 b# ^
Loads are processed by each operator for the following time:8 O M7 o5 \# u9 w# k
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* `( y- M7 C/ H; i* 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. Z3 ~, |; P+ ?; h( T3 u& ?
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
$ y3 U3 c1 I D3 U7 g& @ y( ?, DSend 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.* e, Y6 W# a) k/ Z1 A0 f! m
9 M, l6 r; ^9 J0 t
问题:
& O; C$ n- M& ]+ W6 QAfter running the model for 10,000 days, what was the average number of loads in each process?
