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,, [: Y& i$ z1 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.
j( B8 ?! m# G0 m4 U Loads are processed by each operator for the following time:6 F0 v% ^ _0 n1 R
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
" K7 ?* f, _- ?9 f/ W" k8 k/ T 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.
+ K6 ]" E; F/ d! N- j5 L Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
( g# @* j# G) _* ySend 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 ~) D+ j4 y9 F% G+ x/ k' f! h& e& a" i7 U2 Z) S. w$ ?# x& S8 g+ k
问题:9 I S# c2 f0 W7 p
After running the model for 10,000 days, what was the average number of loads in each process?
