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,+ n* t+ O' Q0 y. B8 t3 ^
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.
, i+ v# f; \- T) D$ s Loads are processed by each operator for the following time:- ^; K, R6 w Y9 J$ n# o/ G; M
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 v7 L2 q) V7 k2 L! c( K8 T) m
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.
2 M6 X) q* @, J4 N3 w+ A Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
$ Y. h* W& S! w" R& W- [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.* d: E0 |+ T) E

After running the model for 10,000 days, what was the average number of loads in each process?
