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,
/ f6 f8 H: e; y& n( B# G  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.
, r4 t% F1 D2 [  Loads are processed by each operator for the following time:
7 |! ~+ N( ?% Y/ |# m% k! k  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
( i% u5 o2 @3 O! s$ j* E$ 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.
. K8 h$ a# g. v. X  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 O7 g' V/ s$ g( R  qSend 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.
" D; {( t+ l$ J: I# ?! }/ O! [0 z& o) {/ U
问题:/ ]2 s2 m3 j5 Q* r0 \! [
After running the model for 10,000 days, what was the average number of loads in each process?
( F$ P& }% Q) y6 y

P_B and P_C is similar

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.

Remember to turn off the animation before you run your model.
