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,& M+ a$ C( U* r0 L, Y1 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.
- j  K6 q+ @' S+ e* T$ c% p7 B  Loads are processed by each operator for the following time:, S" s. B; o4 g' Q' k1 j
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' s% q0 `8 B+ t. d" `  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.
( `& F6 o2 R* _/ S  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 _. I. p* {( [" O
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.4 `/ |0 i7 Y2 E2 h+ S7 H* `
