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,
" @. B# ?9 A- _$ r 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( w: D0 ^+ E" z
Loads are processed by each operator for the following time:- U+ o: f3 R j. j6 q( T
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.# b% q1 ~/ u/ S" F* }
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.
6 K$ o/ Y0 g$ }) w9 g1 A Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& Y; K" M6 i* d; E; _# N
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.! R! N$ L- D$ D; ]5 P0 O
" b# T( V! ]; O1 F0 \( H. p6 q问题:/ N4 | I; i, T" k
After running the model for 10,000 days, what was the average number of loads in each process?
