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,
! G+ d) O# x6 r' ? 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.
7 Y% d$ o9 x) \7 u% `( w Loads are processed by each operator for the following time:
[. ?9 H/ D& @. R3 u) B Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., _* V0 \5 M s2 v. r$ H; 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.: F# n) \9 t* Q# F' _! ~$ G3 m
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& y: F5 M1 K- u9 d
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.$ K/ R- N/ b8 v/ J1 [& K0 ?
0 D0 C2 u$ g9 p: q2 T7 |
问题:
2 B$ v; |" I: \After running the model for 10,000 days, what was the average number of loads in each process?: f/ ~% G& h& x! v& T
8 L* L, _, O _不胜感激! |
