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,
1 P% M0 y% D0 \ 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.# d; ~) L* g; |+ ]
Loads are processed by each operator for the following time:: X" [5 H% w! `- E. K5 n
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
8 J4 J, q5 V3 }* Z5 [1 F" v% k 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.
8 O; V, {* R- j; f) P Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
' C2 @* e, i8 E4 e3 c' @3 [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.
, J. V8 g: a! G/ Z: h; J! @& t8 u9 ~, r* C
问题:- M* j# t8 o7 u$ g/ Y
After running the model for 10,000 days, what was the average number of loads in each process?: t k; X+ A# i! T# {+ R6 `% ~# U
# ] B& H& n' \( S不胜感激! |
