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,8 M+ S; y. E9 D& M
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 u: s, ~, J6 t
Loads are processed by each operator for the following time:* c1 c# X% c- \. x- L4 V
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ R% C0 E- n4 ^: O% T+ N1 O4 z, R 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 L u& [, s, ~3 c n% L Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; Z' g# l$ B& G9 H" l
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.! S0 f$ h) L5 N- J/ s- P
8 i- X1 ^8 B( v) D. b5 \
问题:& ]: d9 N0 i6 G* W: [6 E% @
After running the model for 10,000 days, what was the average number of loads in each process?$ J$ A. o* k) i' D- y( v
