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,
, t6 n) W4 |1 G$ \ 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.
O. }* a! A5 v Loads are processed by each operator for the following time:8 L1 s+ q4 p/ ]) J$ q* p
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.( N5 k% K# ^+ e9 b" r& {
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.
3 q' [8 v% w: ?/ J5 N( p7 q; { Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 @1 _9 A0 l( v# Q# s) m# Y/ Z
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.6 f6 A3 I) s/ i
+ c) n, o2 p N# x8 v, F问题:4 P) j: e, `" I1 ?/ ?0 }
After running the model for 10,000 days, what was the average number of loads in each process?- @ G% [$ v/ q5 x+ ^
