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,* s0 j9 H2 f- j3 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., z* b g; \$ o6 z& ?
Loads are processed by each operator for the following time:
/ M2 [, c+ D/ n* {/ M0 _: g Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. S j& D, b4 j" t9 K" C$ _% L& c& J
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.5 h2 r1 F1 ^. `; F8 C: V0 ~$ u! K3 B
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& p6 ~) D6 i- N" h9 W+ Z+ l; 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.
