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,
3 n% X1 v$ T, j {( M 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 G0 N2 z" ?- H2 x- _9 K
Loads are processed by each operator for the following time:; \- ~5 H7 O# ?
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ b: s6 c4 k1 ~' r# y2 Z2 z3 O; Z, B
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.
l7 y& C$ U6 O. U Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 R. ` x. N1 DSend 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.& I( h9 c5 {& i% v0 A
7 F' M: {0 \" [6 N0 Q+ s问题:$ [1 Y4 W. _0 g ?& ?; n
After running the model for 10,000 days, what was the average number of loads in each process?6 Q# K; k4 p k' ]. d
