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,
+ k% X9 [6 L6 [6 ~  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.
: z3 R) y, M$ o. G2 G! f  Loads are processed by each operator for the following time:6 C/ J  \0 F/ q1 D) J5 @  K
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& Q  j) a: v* J
  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.# H0 H- i8 m" g. h" ~6 x* W: I4 T
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" |6 F0 ^& {0 H% @' W5 X$ ZSend 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.
, q$ X7 A& H3 a! @" i
6 l9 I( [8 H& C问题:& W! @; P9 r9 ?$ x$ m  M) ~
After running the model for 10,000 days, what was the average number of loads in each process?+ l4 z3 ]% `& h

不胜感激!

% b. N3 u& Y8 Min P_C, you need to send to die.

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.. Z7 [8 u. Z( m
