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,% F4 l( a3 M& y, D* Y+ J
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.
2 x7 M" Q! @9 a+ h; [ Loads are processed by each operator for the following time:
& }4 y9 r: \: O Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ k; u+ W; U/ I( X# V 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.
& G, \" w1 B' P7 j5 K3 W9 S! q% c Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 c; G# _4 D, L( ]6 p+ a$ @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.2 W# i( o. {" _% E, u7 y1 k1 a3 U

After running the model for 10,000 days, what was the average number of loads in each process?+ A1 I: t! |- Y1 O( X
