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,$ `4 [* {: w+ }, ? S
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.
. U, d5 ~! o4 \, ^2 r3 b& X. [9 g ] Loads are processed by each operator for the following time:2 t v9 `2 j1 F" }! d; X/ r ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' D5 @5 ]) m& ]) u# f6 D* I
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.9 [$ r, x' D i" E$ D% \
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 j: u& }8 T. ?
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.- D1 o- b! h: T# e; V+ U

After running the model for 10,000 days, what was the average number of loads in each process?; V* g5 ~" [6 ?# H7 `' B
