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,
* U, j7 y* |; O7 g+ r 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.
8 i* i* \7 N! K* B7 X! s6 l: v3 { Loads are processed by each operator for the following time:
! D& c& ?7 ?& ]# T3 F) K& ^ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.% D' f8 F* z2 r! K
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 p0 W/ ^8 ]- ]" P( c/ m7 f
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ E: v4 K: O% {, \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.
; {! \8 P4 H! ^4 I* C" l5 K7 K0 k2 G: o* V( R9 L: a
问题:
* z& M* t3 v3 T( d( FAfter running the model for 10,000 days, what was the average number of loads in each process?
