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,
% {3 y# m; [/ h' z4 o- _ 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.4 s% m2 l! `4 E) N: [- I
Loads are processed by each operator for the following time:
- R- u7 C8 A/ @ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., I$ _" L! w: p9 n
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.6 J* k6 N( j8 D2 c
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ |0 \+ ?! w, e. B* XSend 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.) Y% M- T: s1 n# s/ H
; b& ~% u9 r8 r4 x" I; z
问题:* j$ K9 _/ G! E- x/ E
After running the model for 10,000 days, what was the average number of loads in each process?5 I; G/ Y8 G1 n
2 h% c4 p& _, H! V' N- `不胜感激! |
