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,
" A1 ^% `/ u3 \ 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.
& c0 R- f' \# v Loads are processed by each operator for the following time:
& |7 _2 [( V; l! @! r! L- r7 W Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
: g8 x& v- p3 G2 x: a 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.
5 f1 f. @& @" ~3 T! E. J9 l( T Worker_C does the job in a uniformly distributed time between 30 and 90 mins.5 i, o8 _' ?% @& G
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./ @7 I1 @! Y3 c7 E6 {* X

问题:# u! m8 N6 h$ u# r w
After running the model for 10,000 days, what was the average number of loads in each process?
