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,
- h# b1 x; ]; J+ ^) }  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.
  g* d1 i0 v/ F9 e/ h  Loads are processed by each operator for the following time:) w  r, B! }& B9 h
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& B' W" U+ P/ u+ 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., `/ _2 C, y) H( q
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.. K$ t0 D: e7 g' S: K
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.
3 j  r2 C! r1 A/ b/ B2 T# K, J/ J& h! c
问题:* V2 f' Y1 x+ X
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!

P_B and P_C is similar

in P_C, you need to send to die.# J, D4 C1 }# f2 J' U! @$ D

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