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,! |" r  _8 |9 ^" ^5 }
  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.. D' h1 O# Q' s
  Loads are processed by each operator for the following time:! Y) ^( A5 h- U8 R9 K2 r7 u
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
) w# }( l% ]! ~  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.
9 `8 b: i2 o. c% n4 k! R4 f/ c& U: L# h  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; t7 A" p& [- |* M  r
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.
1 D! L+ \4 P& X3 {) K# ^% r6 w9 f/ s
8 p  G6 l) f$ v4 f: l8 B( L% T问题:, Q$ K8 k6 {2 e& g
After running the model for 10,000 days, what was the average number of loads in each process?2 u  `& ^6 l5 l* }+ j3 y

P_B and P_C is similar

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.

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