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,
% Q+ ?8 u& L; e5 P" N 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.$ W- u) _3 K- O; Z0 m
Loads are processed by each operator for the following time:
8 ^$ f+ `- C; [( w6 v; l Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! j5 S( D/ _" s/ u3 u5 c5 V 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.
/ G! z" _1 n9 r0 A Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: m4 T' B% n; l! t+ ?$ L* t% p
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.8 T1 Q* f$ K+ q+ _' p$ Y, @. E
