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 A/ R9 u+ L: E; v% v 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.# F. E4 y: k1 W# K x- x* v5 |
Loads are processed by each operator for the following time:
4 g3 y9 F6 P( T+ p) J. s% N Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 d( P S8 {3 v5 ?1 @ 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.
- U# D$ X$ ~. i; M, {! P Worker_C does the job in a uniformly distributed time between 30 and 90 mins., x4 o* V0 i/ |$ G: p+ X
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., P* L" X$ s9 i& W8 c
9 K/ X. d4 A: r5 l! I& M W
问题:# {( a# D" L7 G6 g
After running the model for 10,000 days, what was the average number of loads in each process?
