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,
; `: ?/ G6 l ] @1 T6 f. ]5 t 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.7 b9 [% m; [' z% S" Y& P
Loads are processed by each operator for the following time:. H6 K$ j+ n% |, A! _8 e! L9 Z- R8 ?5 b
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
8 g0 Z) Q6 D+ F8 Q$ |6 H 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.- |9 R! u* N+ J; E# [+ e6 X
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& D/ X) X$ S- k( W- ?) ^2 L0 ~& QSend 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.
# _4 |6 S$ o# @1 i9 ]) W3 I5 {( y5 m# j9 L3 L5 Q1 e8 q# P* ^; n" s# C" J1 J
问题:
. w7 A, j% `6 G( {- EAfter running the model for 10,000 days, what was the average number of loads in each process?
# t. `1 C7 q ?0 k3 M0 Q/ {3 z t3 D) k2 c1 J8 h$ Z! q2 v
不胜感激! |
