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,
& h5 K4 x5 g! F' U 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.
1 ^) ]: b9 z/ \* a8 f1 C Loads are processed by each operator for the following time:
3 b' c5 U3 z* p+ `" ?! R: R Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." c' t: x- ~+ Y" G! E. k' Z/ q
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.
( G0 \4 r9 ?3 p4 |6 W+ h Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( f& `4 c0 w; r* 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.
+ B8 h& S. q, n6 r; H& Z. V; R& ?( |. o/ b
问题:
