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,
+ k [( Q0 I9 z( g$ Y 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.% q; D/ A2 Q! Y K5 r: v! w
Loads are processed by each operator for the following time:
% R' G4 B4 m0 [! H/ [8 G7 x Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* h- f3 M: J4 S& q 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.7 E) r2 y( F) y4 f: P
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: m9 y4 r+ \( \
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.+ W% ]5 i$ i- G1 F
7 u& u& \4 Z' y5 J3 c
问题:- u6 r" A+ G9 L* Q
After running the model for 10,000 days, what was the average number of loads in each process?
7 m0 e- z( M2 Y. i s4 S. }. G- K' f/ N( t' n
不胜感激! |
