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,
! H# `) N2 R6 t6 K# E- z 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.
$ \, I* t# O# g: H5 F Loads are processed by each operator for the following time:
4 B- E; Q+ ~# L7 K# j' V" X4 ^' W Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.- L; Z+ K9 _4 E, n# W, 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.5 u- i* }4 E0 e5 C1 r" F3 ]
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 i) ]5 C! I! Z. r- B6 `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.
% q* }" a' {0 d9 P; ~6 j ^( S
