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,
0 i7 r7 w( q6 D9 f; d) c# } 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.% M8 ^2 D: ?7 N: ^" B" w, y7 N: O N
Loads are processed by each operator for the following time:. b: r" W! J$ D, x: z2 g
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' O8 Q1 A9 P' W7 s* s1 W 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./ X, w1 m5 G g
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
; f* i" u6 E: ]2 I4 E1 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.
& u- g- a% w S5 O5 i) D8 ?: a3 e" N8 l! l0 o
问题:
( w9 c; N8 Z# R; F. F! y! iAfter running the model for 10,000 days, what was the average number of loads in each process?
! s% U0 `' M8 B4 c* M# e3 J) u& {3 G- E/ b: C
不胜感激! |
