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,
: |, U& w+ h8 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.
! V* g7 M: i0 ~ Loads are processed by each operator for the following time:
4 W9 ~) ?0 F. |- P* {7 V+ E Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. H8 X0 l! Z) c/ t1 { 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.2 v4 {4 H% o" t) U8 o1 G3 R" u, o
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: b4 m- A0 m+ p8 FSend 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.$ A" c% h& r' |- L3 S

After running the model for 10,000 days, what was the average number of loads in each process?' n1 Z( l3 D+ [) r( ^7 f
