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,+ G1 u8 ^; d3 B7 \, s( k! 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., h' R( O. y( d, K# F
Loads are processed by each operator for the following time:
& ]& o, O8 u* Z( N. [. h Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
S& n+ j: b6 @: v 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.
/ D4 l& {- k( O8 \ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% @! n3 G% k4 rSend 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., F6 C# o0 n4 K% e5 [: X
& H! X1 K- C" b! l. [9 _ ^3 w4 K
问题:
% J [7 J! P* N. I+ L; YAfter running the model for 10,000 days, what was the average number of loads in each process?" d V2 G/ m. n4 P
1 y( k% c5 C% I
不胜感激! |
