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,0 d3 B5 Z" ?3 v' u0 f
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.
C5 S" z3 V/ G' i2 o- w$ l; S Loads are processed by each operator for the following time:
! j8 j) \1 r1 s# x Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 s5 L/ l! h/ z& c; t1 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.
: j e+ L% p' ]5 q: A+ G Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 u+ X: t2 t+ b* c6 BSend 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., R; p! i+ k5 Q) s" I
1 ?" d7 s, J+ F
问题:
) N- u, i: G+ QAfter running the model for 10,000 days, what was the average number of loads in each process?
