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,8 o4 w- _4 l3 W4 o* R3 H5 s
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.1 V/ u: I. V0 L
Loads are processed by each operator for the following time:
' ?, u9 r# Q* {" z% \% a) r Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& b( |. K: j" k4 c1 L4 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./ n; C: ?6 F5 c5 q) G
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 S9 I; G$ u9 X* pSend 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.' q/ R k8 ?; D
