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,
) t) L* N- I8 \1 n7 Y& h* S2 n 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.+ r$ I d. R1 ~ m
Loads are processed by each operator for the following time:, ?8 I! v$ h A
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, d& D' Z: `# C; Y% E 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.$ Q! t- R% F" p, ^- z* l" S& q6 U
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 k' O! J# E* I% u8 i. m* ~# @
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.9 d# ]4 O% D6 _" S& i1 Z9 h
1 L+ d. k8 S+ ^* i问题:: u2 f) b) Z$ V, k
After running the model for 10,000 days, what was the average number of loads in each process?
