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,
0 u9 n( {) {+ y 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.5 z3 @- o* O1 [, x/ x; b
Loads are processed by each operator for the following time:
9 w9 Z# [2 p- _: a. z Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' v7 P. e+ h; Q7 s( Z0 b
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.
7 p, w* s7 Q0 k' z: z+ X Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
f! F9 K: |; ]7 |% N8 e; E2 NSend 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.
0 S: l. l. Q( O* C9 J c* v
0 N& r' u9 j, q4 w3 ^问题:
% w, J1 L$ P X3 @: K0 \! cAfter running the model for 10,000 days, what was the average number of loads in each process?2 r# V# I! _, z: y
2 i& a4 W7 r( Y# }" M: U6 \& x
不胜感激! |
