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,* m; s9 B" E G/ j5 \
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.
* G' V; N. c+ N" x( K+ a Loads are processed by each operator for the following time:$ W$ _6 }) o$ G0 Q; w
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.$ P) ^* `" ?/ c( @: g
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.5 e$ z7 M0 Z" ?9 u; m0 i
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
8 L1 ^/ O5 m7 X: d- O% 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.
8 {- J1 m$ t+ h* c" k1 V* n* V7 f- C3 ~0 R9 `. h
问题:3 c, o8 i! P4 R
After running the model for 10,000 days, what was the average number of loads in each process?5 o$ O/ e% B4 M. e, w# h
# x/ G7 Z. ?, h3 ^5 t: y
不胜感激! |
