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,
$ T1 @# S% t( k' G- D; W5 u% {1 x' X0 q: O1 i 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.
0 N* j1 |6 }8 m l% Q M Loads are processed by each operator for the following time:
$ P! G, i: S2 k1 h1 V; E* p Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 X6 m( f/ z! Z2 \' ~! C2 q 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.( N* o9 w% k. H* o: i$ w, q
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.$ O# L, W. q# W. F& M1 L
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.
: K' R- ]. X% B" E: g/ W3 e& \: }' q7 V) n# y+ p5 F

After running the model for 10,000 days, what was the average number of loads in each process?0 B. y3 E" {+ w/ U- U3 q
0 U4 E. m6 X6 o1 w4 g
不胜感激! |
