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,* [5 c* g( P3 n# k1 x1 v, A( K7 |
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* [9 F8 g0 S! v* x
Loads are processed by each operator for the following time:
9 j! R0 h; g3 ~$ g) L+ x' C+ y Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. \2 S0 N9 r& B9 F# @6 R 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.
& l' s7 u3 n, R/ j9 p Worker_C does the job in a uniformly distributed time between 30 and 90 mins." E) t: `; l6 }; T( \
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.% s" V3 a- e8 Y! A

After running the model for 10,000 days, what was the average number of loads in each process?( s8 ]6 h2 f3 _
