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,
8 N8 E i! N1 s7 @' X# ] 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.
$ j+ g9 E) u$ F" d0 }5 J" G q6 o. [ Loads are processed by each operator for the following time:
5 V( b$ l' f# Y+ w2 O$ V$ {' U# X Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.% w$ Y0 i* W. e; n' l% p
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.
# @; w2 H3 z! z( q Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 Q5 D: V' h2 m E$ v! P. W: C
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- {$ L. v. c( `; I- \' F! w) s; _

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