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,
5 x, @( |/ ?; r+ F) f' x 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.
# a" p2 {8 M% S4 b- N, R* U Loads are processed by each operator for the following time:
8 [ Q3 k5 h8 ^ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; P5 N* ~" O" N8 Q# ?: 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.# A5 [' x& I4 |4 {& h4 k
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.$ e6 B* x1 F& A* G5 s6 e. e
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.
8 ?% ?7 t8 @& i' t6 H& G; G" P; \& Y; ` U) U% [% ~) i
问题:
4 p+ o1 S q7 J. t( n. ~After running the model for 10,000 days, what was the average number of loads in each process?
( C+ Q6 R, D6 j
