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,
) r# Q; j# m1 K% a 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 J8 [+ N. B( z( ?2 I: m
Loads are processed by each operator for the following time:6 y: f. [7 b3 p) l; N" G5 p( g' J( a
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 D' z. [1 c, V; [6 x* B, C( z 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.' A, e1 w* Z2 ^% M5 H0 c( }7 Z
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, {# h0 K; R+ }. jSend 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. B' m5 y" ~1 G2 Z: x5 |4 b
3 M( K, F; P" g0 P
问题:
* w/ @# N$ @" D. }( uAfter running the model for 10,000 days, what was the average number of loads in each process?
