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" y9 q# b2 ~
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.8 t' ?+ [( K5 i2 c/ w2 g7 l% ^- S
Loads are processed by each operator for the following time:
v( |, ~+ l5 F; K! G( W Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' Y! @ J2 l0 s2 y$ V, Z T9 M c) A 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.0 j6 d3 U8 v" M V7 j1 y- N
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, w3 t1 z4 [0 M' Q+ USend 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.
