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,
* H7 b- G6 E. }' f* U 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.
% p3 F' r" J+ Q$ t- J& G* K Loads are processed by each operator for the following time:
3 P9 m( Z- }- G Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 k9 |, {. g0 A* G8 u4 ? 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.
1 L% Q9 |3 z% }, L0 R3 ? Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 [& S' e8 r q
Send 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.' Q8 l& d5 o0 F: a6 V( _" T/ W: @

After running the model for 10,000 days, what was the average number of loads in each process?4 q: h$ ]: m# T& [# s0 V# R
