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 c# J, M( d; 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.
4 K/ n! S9 u8 p/ z$ L. H Loads are processed by each operator for the following time:
L3 W3 t8 ?, e3 K/ ]: o Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; ?5 ~2 f' r4 o7 c. R7 e" X+ g
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.
% Z0 p2 A9 C; f, k0 n- x' D+ b7 ?& l Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
D+ I. B4 p9 V, R6 j3 G4 t6 l' K- x% ASend 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.- F( E/ u5 X* l3 b. m. O6 g# s

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