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,: v6 h; a8 L; z
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.$ Y5 B! Z+ C; w
Loads are processed by each operator for the following time:
0 H! G. {4 S) W F* g Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
# x/ W2 O( ]9 H8 z 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 k, d3 ?6 X6 p M
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
' v8 H S; A) Q/ B" l1 j( lSend 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." L7 w. A; s# ~/ j
! x! L+ T. V4 }: m. H$ p问题:
/ ]: P- ~( P, U- ]- U- q5 {After running the model for 10,000 days, what was the average number of loads in each process?$ G0 M7 H# @' T/ v# n$ _/ F
