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,
) V3 g& I$ F8 q1 Z0 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.* g" E# ?$ q; D+ A U, i; A9 P
Loads are processed by each operator for the following time:
7 V. W2 c7 i4 A/ v$ {4 y$ N$ f- L Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! x* t* B' r# N; ^$ }( v 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.
$ R' y' N, d6 ?1 M! V) n Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 z& H7 k( t) s/ pSend 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- y4 q7 }) R- M4 Y, a$ q7 C) Z% r2 `7 m7 H/ q
问题:
! s( j/ K& z8 w& D$ n; [9 DAfter running the model for 10,000 days, what was the average number of loads in each process?( s7 }- {# n1 E4 C' s
* l6 ~: [; g2 U! l, l
不胜感激! |
