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,
- J& f$ p4 E4 {5 T- S, H 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., m; N5 o2 k8 S: V+ `
Loads are processed by each operator for the following time:
P$ W7 {) [* x; W; l% M( Q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.* O5 u }) J# B3 x: A9 Q0 c
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.
% t+ v0 b) v. @" k" Y/ l$ r Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) Y% r9 Z0 b% u$ i+ ^5 USend 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.
K& _: T. k0 Z0 Z* S0 E$ u& M& H2 \
, h' W" h% ?; E3 T6 N# u. v; y问题:
% b) x0 [+ w5 B9 V- V7 {After running the model for 10,000 days, what was the average number of loads in each process?
5 ~- G: k: I9 `! m4 C9 a% v- Y8 b, Z$ [, v6 U
不胜感激! |
