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,
% V) s! k9 ^. r3 l% ?: J! 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.3 Y+ H/ k6 Y/ |
Loads are processed by each operator for the following time:
* L* t" E" v& f) @1 |& X- @* X Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
/ r/ M6 R) c% O; \ 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.
; c) I3 w- H; N* O; [3 U4 | Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- C5 x* P. @! U; Y
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.
! i$ R( n+ Z/ A0 J& u, S y* k) P3 k% \* T9 T$ F" t* ?$ O B
问题:) g7 }6 h# R+ q2 q3 Y
After running the model for 10,000 days, what was the average number of loads in each process?
