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,
2 ]7 x8 T6 }' q# ^, [ 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.
6 C! Q: m9 g4 Z- G3 G Loads are processed by each operator for the following time:8 F1 W6 e k# H0 |
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' _( I1 o8 _0 I9 O7 a# D, 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.! R6 d2 }$ m4 b, W2 I( ?
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 y9 B1 I0 v, N8 c3 q$ ESend 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. s, a7 ~1 T8 i% L5 j. N7 M

After running the model for 10,000 days, what was the average number of loads in each process?
