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,; n$ o( t( E0 u8 ~& H* @" w
  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.
/ I- y, J" c0 x* J3 T  Loads are processed by each operator for the following time:. ~1 q6 Q5 K( l8 ~1 ?& N
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.) @8 X: T. r- p1 c% c
  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./ \+ T6 j2 P9 r
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins." A# g# e9 x) f( 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., w' q; K4 t" e0 ?
, Z; P* y2 Q' d" g* c
问题:0 q# |% Z8 p3 A' r/ X. Y; U: m
After running the model for 10,000 days, what was the average number of loads in each process?/ F) ?7 t/ q  z+ V; P

不胜感激!

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days./ a. b# e3 h- ]3 B( z
