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,
4 P$ r% K7 A7 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.% z7 C2 F% _! D9 z6 g
Loads are processed by each operator for the following time:
9 f. d9 j/ k1 f: m# ] Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 I$ q* r; Z) x- {* y, U' H- | 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 L# `$ s) ?2 ?6 R! U6 I" T; v% o
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 p9 O6 n; A! _5 M; P; i2 ISend 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.! T, w; X- J% a) E/ A4 t9 G
# y$ o; ` G9 z
问题:
. t, B; o$ L7 g- P3 [9 A/ ^2 [" e# GAfter running the model for 10,000 days, what was the average number of loads in each process?% D2 M% O. A0 V, r. A6 y
6 E% S6 j+ R' ^- U6 B不胜感激! |
