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,
( k- W+ A+ d* F2 t% K 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.0 e1 B% s2 s7 e/ }, E
Loads are processed by each operator for the following time:
$ k9 s. H: E& j( L1 @ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." C% x) ^3 G# E2 K4 u8 E
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.; z$ m$ R N) t$ S6 k- p# _2 T
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.9 J6 t B M+ {% r: m4 i# M z: ~
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., U* k, S$ K& X. f" b) Z, I
9 j! N- f0 K8 V v* R L v: n
问题:
# t8 j" y: ~, }' V+ ^6 z3 ^9 Q5 jAfter running the model for 10,000 days, what was the average number of loads in each process?
