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,
: ?* \6 a" {9 q- t5 ~6 Z- B 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.& t6 x; F% E1 a# W/ i% I$ S. H
Loads are processed by each operator for the following time:! l. \2 `0 C4 ^$ j) p- g; l
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- }( W" F/ b( @: ~3 ^4 r+ e8 m 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.
, w5 B, \1 A$ f+ H3 F; S Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 q9 d( e+ G- M: k0 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. x* Z! `+ C" f5 _; c3 z* j, W
6 B4 T2 z M+ `: C问题:
, @( U9 Y( E$ \2 D; f: r) tAfter running the model for 10,000 days, what was the average number of loads in each process?
