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, |* `5 q) {; N' m0 t) Y/ H8 o6 h' t! \
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.
2 `5 C M1 J) g: ]- [+ k: v Loads are processed by each operator for the following time:
' P# K' R! {. M+ ~+ s4 h Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
1 {$ u+ }- w- R* I% I 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.8 ^* J* g/ |- I9 f5 g* U8 V# @
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
