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,, ~ H2 k# A5 r+ U
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.
& v4 M' _. j: O2 x2 [4 K1 h Loads are processed by each operator for the following time:0 C. A- e1 X2 r2 P; v8 j( M. I& @
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' g8 s, m% x" Z- T4 G. O
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.+ k( [" N4 D" h3 B9 z
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
