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,
! c3 s, W2 j: D/ V4 M _0 U 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.& g( f V5 z6 T$ E& a
Loads are processed by each operator for the following time:
% W; K& v) _7 R$ i2 k1 T Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
) T% E# f+ z. ] 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.
/ j/ h0 A' I7 \: ]4 a# W8 _ Worker_C does the job in a uniformly distributed time between 30 and 90 mins. b5 b1 r% S- i: b/ h3 F" B
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./ t; w1 d4 H9 E3 `5 o+ c& K5 r
% Y0 a) b& d" ]1 o9 B2 f
问题:" t- F& X: i! k9 C' e" P7 A5 [; k
After running the model for 10,000 days, what was the average number of loads in each process?% |' Z! `) R, l" J
