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 E/ _4 A1 E( p9 R! v
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.
3 ~& q) a. t% v5 p V Loads are processed by each operator for the following time:
, j& G0 h3 r8 z' u1 ^ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
" a: V- [7 X4 ~! |7 h& X0 J 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 I/ W1 O t Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 H5 s+ ]/ Z! U1 i& ~4 h0 MSend 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.
9 e# T" S% d5 L: X4 j, O3 D9 ~: l1 s2 c* ]2 ^$ _/ y4 k3 ?
问题:
4 O5 w. R- a6 hAfter running the model for 10,000 days, what was the average number of loads in each process?
