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 P N c$ t& Y; B% L( c 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.
; y; \% O: O3 E( v0 b! A) w Loads are processed by each operator for the following time:% H6 C; i& {' m5 E/ s
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. D1 w5 Q, \6 K- N/ e6 @ 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.
4 n0 v3 h# N( z7 \ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 q5 R( Q! T5 h. c' x+ Y TSend 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.( `9 w6 D- ^# h. @/ b

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