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,
. p+ S6 j& Q4 P8 v( M7 c% m& r  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.
7 j6 N  M5 ?! c# {  Loads are processed by each operator for the following time:% I0 C' g& X$ W
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% a5 R; T  o& W/ f' Z$ Y- s  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+ H0 }$ B0 {, Q) _$ Z
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.9 x4 W* D' ?& ]; {% i
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.5 o1 ^, N2 I. E% o/ L" W

, M6 K; J8 l1 f9 G0 L; i问题:' ?  M5 m. ~3 I
After running the model for 10,000 days, what was the average number of loads in each process?

in 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.+ N, ~" |6 Z  ~/ N0 P0 R+ V
