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,
+ p/ Z2 K7 r$ g- F" s/ \8 E9 B1 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.
0 v4 Z0 K- [ [ Loads are processed by each operator for the following time:5 \- j" k! i, M+ c+ a
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 A# a; k8 t/ E
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.% g1 A+ B5 ^# Y: r
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
. l) k0 T& k7 e# l( X7 n7 cSend 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.% Z7 K6 h8 g+ Z* e" K
1 i7 V7 E$ g! h5 q% [: k
问题:' g$ E$ y( {7 @3 [6 i* r8 m0 ~
After running the model for 10,000 days, what was the average number of loads in each process?$ B; I5 m3 D! `" ~% A+ e5 _
, C% J7 D" z5 f" n/ Q) E- t- n$ j, Q
不胜感激! |
